||||
This documentation provides a comprehensive analysis of how the Kiwy-Signage player (https://gitea.moto-adv.com/ske087/Kiwy-Signage.git) handles HTTPS connections and SSL certificate verification, along with implementation guides for adding self-signed certificate support.
|
||||
|
||||
**Analysis Date:** January 16, 2026
|
||||
**Player Version:** Latest from repository

||||
## Key Findings
|
||||
|
||||
### Current State
|
||||
- ✅ **HTTPS Support:** Yes, fully functional for CA-signed certificates
|
||||
- ❌ **Self-Signed Certificates:** NOT supported without code modifications
|
||||
- ❌ **Custom CA Bundles:** NOT supported without code modifications
|
||||
- ✅ **SSL Verification:** Enabled by default (uses requests library defaults)
|
||||
- ⚠️ **Hardcoded Settings:** None (relies entirely on requests library)
|
||||
|
||||
### Architecture
|
||||
- **HTTP Client:** Python `requests` library (v2.32.4)
|
||||
- **HTTPS Requests:** 6 locations in 2 main files
|
||||
- **Certificate Verification:** Implicit `verify=True` (default behavior)
|
||||
- **Configuration:** Via `config/app_config.json` (no SSL options currently)

|
||||
|
||||
## Security Considerations
|
||||
|
||||
### Current Implementation ✅
|
||||
- ✅ SSL certificate verification enabled
|
||||
- ✅ Works securely with CA-signed certificates
|
||||
- ✅ No hardcoded insecure defaults
|
||||
- ✅ Uses Python best practices
|
||||
|
||||
### Self-Signed Support (After Patches) ✅
|
||||
- ✅ Maintains security with custom CA verification
|
||||
- ✅ No downgrade to insecure `verify=False`
|
||||
- ✅ Backward compatible with production
|
||||
- ✅ Supports environment-specific configurations
|
||||
|
||||
### NOT Recommended
|
||||
- ❌ Using `verify=False` in production
|
||||
- ❌ Disabling SSL verification permanently
|
||||
- ❌ Ignoring certificate errors
|
||||
- ❌ Man-in-the-middle attack risks

|
||||
│
|
||||
▼ requests.post/get(..., timeout=30)

|
||||
|
||||
|
||||

||||
|
||||
Result: ✅ Works with self-signed cert
|
||||
```
|
||||

|
||||
|
||||
### Scenario 3: Development (Insecure - Testing Only)
|
||||
|
||||
```
|
||||
DigiServer v2 (test.local)
|
||||
(Self-signed, or cert issues)
|
||||
│
|
||||
▼
|
||||
Player (with patches + SSLConfig.disable_verification())
|
||||
│
|
||||
▼ SSLConfig.disable_verification()
|
||||
│
|
||||
└─ _verify_ssl = False
|
||||
│
|
||||
▼ requests.post/get(..., verify=False)
|
||||
│
|
||||
▼ ⚠️ Skips certificate validation
|
||||
│
|
||||
▼ SSL handshake proceeds anyway ⚠️
|
||||
│
|
||||
▼ authenticated (but insecure!)
|
||||
|
||||
⚠️ VULNERABLE TO MITM ATTACKS
|
||||
|
||||
|
||||
Result: ⚠️ Works but insecure - DEV/TEST ONLY
|
||||
Note: Add in code temporarily:
|
||||
from ssl_config import SSLConfig
|
||||
SSLConfig.disable_verification() # TEMPORARY - DEV ONLY

# Kiwy-Signage Player - HTTPS/SSL Certificate Analysis
|
||||
|
||||
## Executive Summary
|
||||
|
||||
The Kiwy-Signage player is a Python-based digital signage application built with Kivy that communicates with the DigiServer v2 backend. **The player currently has NO custom SSL certificate verification mechanism and relies entirely on Python's `requests` library default behavior.**
|
||||
|
||||
This means:
|
||||
- ✅ HTTPS connections to production servers work because they have valid CA-signed certificates
|
||||
- ❌ Self-signed certificates or custom certificate authorities will **FAIL** without code modifications
|
||||
- ❌ No `verify` parameter is passed to any requests calls (uses default `verify=True`)
|
||||
- ❌ No support for custom CA certificates or certificate bundles
|
||||
|
||||
---
|
||||
|
||||
## 1. HTTP Client Library & Dependencies
|
||||
|
||||
### Library Used
|
||||
- **requests** (version 2.32.4) - Python HTTP library with SSL verification enabled by default
|
||||
- **aiohttp** (version 3.9.1) - Not currently used for player authentication/API calls
|
||||
|
||||
### Dependency Chain
|
||||
```
|
||||
requirements.txt:
|
||||
- kivy>=2.3.0
|
||||
- ffpyplayer
|
||||
- requests==2.32.4 ← Used for ALL HTTPS requests
|
||||
- bcrypt==4.2.1
|
||||
- aiohttp==3.9.1
|
||||
- asyncio==3.4.3
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 2. Main Connection Files & Locations
|
||||
|
||||
### Core Authentication Module

|
||||
|
||||
## 3. HTTPS Connection Architecture
|
||||
|
||||
### Authentication Flow
|
||||
```
|
||||
1. Player Configuration (config/app_config.json)
|
||||
├─ server_ip: "digi-signage.moto-adv.com"
|
||||
├─ port: "443"
|
||||
├─ screen_name: "player-name"
|
||||
└─ quickconnect_key: "QUICK123"
|
||||
|
||||
2. URL Construction (src/main.py, lines 696-703)
|
||||
├─ If server_ip has http:// or https:// prefix, use as-is
|
||||
├─ Otherwise: protocol = "https" if port == "443" else "http"
|
||||
└─ server_url = f"{protocol}://{server_ip}:{port}"
|
||||
|
||||
3. Authentication Request (src/player_auth.py, lines 95-98)
|
||||
├─ POST /api/auth/player
|
||||
├─ Payload: {hostname, password, quickconnect_code}
|
||||
└─ Returns: {auth_code, player_id, player_name, playlist_id, ...}
|
||||
|
||||
4. Authenticated API Calls (src/player_auth.py, lines 159-163, etc.)
|
||||
├─ Headers: Authorization: Bearer {auth_code}
|
||||
└─ GET/POST to various /api/... endpoints
|
||||
```
|
||||
|
||||
### All HTTPS Request Points in Code
|
||||
|
||||
#### 1. **Authentication** (src/player_auth.py)
|
||||
|
||||
**Location:** [Line 95](../../tmp/Kiwy-Signage/src/player_auth.py#L95)
|
||||
```python
|
||||
response = requests.post(auth_url, json=payload, timeout=timeout)
|
||||
```
|
||||
- **URL:** `{server_url}/api/auth/player`
|
||||
- **Method:** POST
|
||||
- **Auth:** None (initial auth)
|
||||
- **SSL Verify:** DEFAULT (True, no custom handling)
|
||||
|
||||
**Location:** [Line 157](../../tmp/Kiwy-Signage/src/player_auth.py#L157)
|
||||
```python
|
||||
response = requests.post(verify_url, json=payload, timeout=timeout)
|
||||
```
|
||||
- **URL:** `{server_url}/api/auth/verify`
|
||||
- **Method:** POST
|
||||
- **Auth:** None
|
||||
- **SSL Verify:** DEFAULT (True)
|
||||

## 4. Certificate Verification Current Configuration
|
||||
|
||||
### Current SSL/Certificate Behavior
|
||||
|
||||
**Summary:** Relies entirely on Python's `requests` library defaults.
|
||||
|
||||
**Default requests behavior:**
|
||||
- `verify=True` (implicitly used when not specified)
|
||||
- Uses system CA certificate store
|
||||
- Validates certificate chain, hostname, and expiration
|
||||
- Rejects self-signed certificates with error
|
||||
|
||||
### Hardcoded Certificate Settings
|
||||
🔴 **NONE** - No hardcoded SSL certificate settings exist in the codebase.
|
||||
|
||||
### Certificate Verification Code Locations
|
||||
|
||||
**Search Results for "verify", "ssl", "cert", "certificate":**
|
||||
|
||||
Only `verify_auth()` method found (authenticates with server, not certificate verification):
|
||||
- [src/player_auth.py, Line 137](../../tmp/Kiwy-Signage/src/player_auth.py#L137) - `def verify_auth(self, timeout: int = 10)`
|
||||
- [src/player_auth.py, Line 153](../../tmp/Kiwy-Signage/src/player_auth.py#L153) - `verify_url = f"{server_url}/api/auth/verify"`
|
||||
|
||||
**No SSL/certificate configuration found in:**
|
||||
- ❌ requests library verify parameter
|
||||
- ❌ Custom CA bundle paths
|
||||
- ❌ SSL context configuration
|
||||
- ❌ Certificate pinning
|
||||
- ❌ urllib3 certificate settings
|
||||
|
||||
---
|
||||
|
||||
## 5. Self-Signed Certificate Support
|
||||
|
||||
### Current State: ❌ NOT SUPPORTED
|
||||
|
||||
When connecting to a server with a self-signed certificate:
|
||||
|
||||
```python
|
||||
# Current code (player_auth.py, Line 95):
|
||||
response = requests.post(auth_url, json=payload, timeout=timeout)
|
||||
|
||||
# Will raise:
|
||||
# requests.exceptions.SSLError:
|
||||
# ("certificate verify failed: self signed certificate (_ssl.c:...)
|
||||
```
|
||||
|
||||
### Exception Handling
|
||||
The code catches exceptions but doesn't differentiate SSL errors:
|
||||
|
||||
```python
|
||||
# player_auth.py, lines 111-127
|
||||
except requests.exceptions.ConnectionError:
|
||||
error_msg = "Cannot connect to server"
|
||||
except requests.exceptions.Timeout:
|
||||
error_msg = "Connection timeout"
|
||||
except Exception as e:
|
||||
error_msg = f"Authentication error: {str(e)}"
|
||||
# Will catch SSL errors here but label them as generic "Authentication error"
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 6. Required Changes for Self-Signed Certificate Support
|
||||
|
||||
### Option 1: Disable Certificate Verification (⚠️ INSECURE - Development Only)
|
||||
|
||||
**Not Recommended for Production**
|
||||
|
||||
Add to each `requests` call:
|
||||
```python
|
||||
verify=False # Disables SSL certificate verification
|
||||
```
|
||||
|
||||
**Example modification:**
|
||||
```python
|
||||
# OLD (player_auth.py, Line 95):
|
||||
response = requests.post(auth_url, json=payload, timeout=timeout)
|
||||
|
||||
# NEW:
|
||||
response = requests.post(auth_url, json=payload, timeout=timeout, verify=False)
|
||||
```
|
||||
|
||||
**Locations requiring modification (5 places):**
|
||||
1. [src/player_auth.py, Line 95](../../tmp/Kiwy-Signage/src/player_auth.py#L95) - authenticate() method
|
||||
2. [src/player_auth.py, Line 157](../../tmp/Kiwy-Signage/src/player_auth.py#L157) - verify_auth() method
|
||||
3. [src/player_auth.py, Line 178](../../tmp/Kiwy-Signage/src/player_auth.py#L178) - get_playlist() method
|
||||
4. [src/player_auth.py, Line 227](../../tmp/Kiwy-Signage/src/player_auth.py#L227) - send_heartbeat() method
|
||||
5. [src/player_auth.py, Line 254](../../tmp/Kiwy-Signage/src/player_auth.py#L254) - send_feedback() method
|
||||
6. [src/get_playlists_v2.py, Line 159](../../tmp/Kiwy-Signage/src/get_playlists_v2.py#L159) - download_media_files() method
|
||||
|
||||
---
|
||||
|
||||
### Option 2: Custom CA Certificate Bundle (✅ RECOMMENDED)
|
||||
|
||||
**Production-Ready Approach**
|
||||
|
||||
#### Step 1: Create certificate configuration
|
||||
```python
|
||||
# New file: src/ssl_config.py
|
||||
import os
|
||||
import requests
|
||||
|
||||
class SSLConfig:
|
||||
"""Manage SSL certificate verification for self-signed certs"""
|
||||
|
||||
@staticmethod
|
||||
def get_ca_bundle():
|
||||
"""Get path to CA certificate bundle
|
||||
|
||||
Returns:
|
||||
str: Path to CA bundle or True for default system certs
|
||||
"""
|
||||
# Priority order:
|
||||
# 1. Custom CA bundle in config directory
|
||||
# 2. CA bundle path from environment variable
|
||||
# 3. System default CA bundle (requests uses certifi)
|
||||
|
||||
custom_ca = 'config/ca_bundle.crt'
|
||||
if os.path.exists(custom_ca):
|
||||
return custom_ca
|
||||
|
||||
env_ca = os.environ.get('REQUESTS_CA_BUNDLE')
|
||||
if env_ca and os.path.exists(env_ca):
|
||||
return env_ca
|
||||
|
||||
return True # Use system/certifi default
|
||||
|
||||
@staticmethod
|
||||
def get_verify_setting():
|
||||
"""Get SSL verification setting
|
||||
|
||||
Returns:
|
||||
bool or str: Path to CA bundle or True/False
|
||||
"""
|
||||
return SSLConfig.get_ca_bundle()
|
||||
```
|
||||
|
||||
#### Step 2: Modify PlayerAuth to use custom certificates
|
||||
|
||||
```python
|
||||
# player_auth.py modifications:
|
||||
|
||||
from ssl_config import SSLConfig # Add import
|
||||
|
||||
class PlayerAuth:
|
||||
def __init__(self, config_file='player_auth.json'):
|
||||
self.config_file = config_file
|
||||
self.auth_data = self._load_auth_data()
|
||||
self.verify_ssl = SSLConfig.get_verify_setting() # Add this
|
||||
|
||||
def authenticate(self, ...):
|
||||
# Add verify parameter to requests call:
|
||||
response = requests.post(
|
||||
auth_url,
|
||||
json=payload,
|
||||
timeout=timeout,
|
||||
verify=self.verify_ssl # ADD THIS
|
||||
)
|
||||
|
||||
def verify_auth(self, ...):
|
||||
response = requests.post(
|
||||
verify_url,
|
||||
json=payload,
|
||||
timeout=timeout,
|
||||
verify=self.verify_ssl # ADD THIS
|
||||
)
|
||||
|
||||
def get_playlist(self, ...):
|
||||
response = requests.get(
|
||||
playlist_url,
|
||||
headers=headers,
|
||||
timeout=timeout,
|
||||
verify=self.verify_ssl # ADD THIS
|
||||
)
|
||||
|
||||
def send_heartbeat(self, ...):
|
||||
response = requests.post(
|
||||
heartbeat_url,
|
||||
headers=headers,
|
||||
json=payload,
|
||||
timeout=timeout,
|
||||
verify=self.verify_ssl # ADD THIS
|
||||
)
|
||||
|
||||
def send_feedback(self, ...):
|
||||
response = requests.post(
|
||||
feedback_url,
|
||||
headers=headers,
|
||||
json=payload,
|
||||
timeout=timeout,
|
||||
verify=self.verify_ssl # ADD THIS
|
||||
)
|
||||
```
|
||||
|
||||
#### Step 3: Handle media downloads
|
||||
|
||||
```python
|
||||
# get_playlists_v2.py modifications:
|
||||
|
||||
from ssl_config import SSLConfig
|
||||
|
||||
def download_media_files(playlist, media_dir):
|
||||
verify_ssl = SSLConfig.get_verify_setting() # Add this
|
||||
|
||||
for media in playlist:
|
||||
...
|
||||
response = requests.get(
|
||||
file_url,
|
||||
timeout=30,
|
||||
verify=verify_ssl # ADD THIS
|
||||
)
|
||||
...
|
||||
```
|
||||
|
||||
#### Step 4: Prepare CA certificate
|
||||
|
||||
1. **Export certificate from self-signed server:**
|
||||
```bash
|
||||
openssl s_client -connect server.local:443 -showcerts < /dev/null | \
|
||||
openssl x509 -outform PEM > ca_bundle.crt
|
||||
```
|
||||
|
||||
2. **Place in player config:**
|
||||
```bash
|
||||
cp ca_bundle.crt /path/to/Kiwy-Signage/config/ca_bundle.crt
|
||||
```
|
||||
|
||||
3. **Or set environment variable:**
|
||||
```bash
|
||||
export REQUESTS_CA_BUNDLE=/etc/ssl/certs/ca-bundle.crt
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### Option 3: Certificate Pinning (⚠️ Advanced)
|
||||
|
||||
For maximum security when using self-signed certificates:
|
||||
|
||||
```python
|
||||
import ssl
|
||||
import certifi
|
||||
import requests
|
||||
from requests.adapters import HTTPAdapter
|
||||
from urllib3.util.ssl_ import create_urllib3_context
|
||||
|
||||
class SSLPinningAdapter(HTTPAdapter):
|
||||
def init_poolmanager(self, *args, **kwargs):
|
||||
ctx = create_urllib3_context()
|
||||
ctx.check_hostname = False
|
||||
ctx.verify_mode = ssl.CERT_NONE
|
||||
# Or use specific certificate:
|
||||
# ctx.load_verify_locations('config/server_cert.pem')
|
||||
kwargs['ssl_context'] = ctx
|
||||
return super().init_poolmanager(*args, **kwargs)
|
||||
|
||||
# Usage in PlayerAuth:
|
||||
session = requests.Session()
|
||||
session.mount('https://', SSLPinningAdapter())
|
||||
response = session.post(auth_url, json=payload, timeout=timeout)
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 7. Testing Self-Signed Certificate Connections
|
||||
|
||||
### Before Modification (Current Behavior)
|
||||
|
||||
Test connection to self-signed server:
|
||||
```bash
|
||||
cd /tmp/Kiwy-Signage
|
||||
python3 -c "
|
||||
import requests
|
||||
url = 'https://your-self-signed-server:443/api/health'
|
||||
try:
|
||||
response = requests.get(url)
|
||||
print('Connection successful')
|
||||
except requests.exceptions.SSLError as e:
|
||||
print(f'SSL Error: {e}')
|
||||
"
|
||||
# Output: SSL Error: certificate verify failed
|
||||
```
|
||||
|
||||
### After Modification (With Custom CA)
|
||||
|
||||
```bash
|
||||
cd /tmp/Kiwy-Signage
|
||||
# Place ca_bundle.crt in config/
|
||||
python3 -c "
|
||||
import requests
|
||||
url = 'https://your-self-signed-server:443/api/health'
|
||||
response = requests.get(url, verify='config/ca_bundle.crt')
|
||||
print(f'Connection successful: {response.status_code}')
|
||||
"
|
||||
# Output: Connection successful: 200
|
||||
```
|
||||
|
||||

|
||||
## 9. Integration with DigiServer v2
|
||||
|
||||
### Current Communication Protocol
|
||||
|
||||
The player communicates with DigiServer v2 using:
|
||||
|
||||
1. **Initial Authentication (HTTP/HTTPS)**
|
||||
- Endpoint: `POST /api/auth/player`
|
||||
- Payload: `{hostname, password, quickconnect_code}`
|
||||
- Response: `{auth_code, player_id, player_name, ...}`
|
||||
|
||||
2. **All Subsequent Requests (HTTP/HTTPS)**
|
||||
- Header: `Authorization: Bearer {auth_code}`
|
||||
- Endpoints:
|
||||
- `GET /api/playlists/{player_id}`
|
||||
- `POST /api/players/{player_id}/heartbeat`
|
||||
- `POST /api/player-feedback`
|
||||
|
||||
3. **Media Downloads (HTTP/HTTPS)**
|
||||
- Direct URLs from playlist: `{server_url}/uploads/...`
|
||||
|
||||
### Server Configuration (config/app_config.json)
|
||||
|
||||
```json
|
||||
{
|
||||
"server_ip": "digi-signage.moto-adv.com",
|
||||
"port": "443",
|
||||
"screen_name": "tv-terasa",
|
||||
"quickconnect_key": "8887779",
|
||||
"orientation": "Landscape",
|
||||
"touch": "True",
|
||||
"max_resolution": "1920x1080",
|
||||
"edit_feature_enabled": true
|
||||
}
|
||||
```
|
||||
|
||||
### ⚠️ NOTE: No SSL/certificate options in config
|
||||
|
||||
The application accepts server_ip, port, hostname, and credentials, but:
|
||||
- ❌ No way to specify CA certificate path
|
||||
- ❌ No way to disable SSL verification
|
||||
- ❌ No way to enable certificate pinning
|
||||
|
||||
---
|
||||
|
||||
## 10. Recommended Implementation Plan
|
||||
|
||||
### For Self-Signed Certificate Support:
|
||||
|
||||
**Step 1: Add SSL Configuration Module** (5-10 min)
|
||||
- Create `src/ssl_config.py` with SSLConfig class
|
||||
- Support for custom CA bundle path
|
||||
|
||||
**Step 2: Modify PlayerAuth** (10-15 min)
|
||||
- Add `verify_ssl` parameter to `__init__`
|
||||
- Update all 5 `requests` calls to include `verify=self.verify_ssl`
|
||||
- Improve SSL error handling/reporting
|
||||
|
||||
**Step 3: Update Configuration** (5 min)
|
||||
- Extend `config/app_config.json` to include optional `ca_bundle_path`
|
||||
- Or use environment variable `REQUESTS_CA_BUNDLE`
|
||||
|
||||
**Step 4: Documentation** (5 min)
|
||||
- Add README section on SSL certificate configuration
|
||||
- Document how to export and place CA certificates
|
||||
|
||||
**Step 5: Testing** (10-15 min)
|
||||
- Test with self-signed certificate
|
||||
- Verify backward compatibility with valid CA certs
|
||||
|
||||
**Total Time Estimate:** 35-50 minutes for complete implementation

## 11. Code References
|
||||
|
||||
### All requests calls in codebase:
|
||||
|
||||
```

|
||||
Line 95: requests.post(auth_url, json=payload, timeout=timeout)
|

|
||||
## Conclusion
|
||||
|
||||
The Kiwy-Signage player is a well-structured Python application that properly uses the `requests` library for HTTPS communication. However, it currently **does not support self-signed certificates or custom certificate authorities** without code modifications.
|
||||
|
||||
To support self-signed certificates, implementing Option 2 (Custom CA Certificate Bundle) is recommended as it:
|
||||
- ✅ Maintains security for production deployments
|
||||
- ✅ Allows flexibility for self-signed/internal CAs
|
||||
- ✅ Requires minimal code changes (5-6 request calls)
|
||||
- ✅ Follows Python best practices
|
||||
- ✅ Is backward compatible with existing deployments

### Core Authentication (player_auth.py)
|
||||
|
||||
```python
|
||||
# LINE 95: Initial authentication
|

|
||||
## What Gets Sent Over HTTPS
|
||||
|
||||
### 1. Authentication Request → Server
|
||||
```json
|
||||
POST {server_url}/api/auth/player
|
||||
{
|
||||
"hostname": "player-name",
|
||||
"password": "optional-password",
|
||||
"quickconnect_code": "QUICK123"
|
||||
}
|
||||
```
|
||||
|
||||
### 2. Server Response → Player
|
||||
```json
|
||||
{
|
||||
"auth_code": "eyJhbGc...",
|
||||
"player_id": 42,
|
||||
"player_name": "TV-Terasa",
|
||||
"playlist_id": 100,
|
||||
"orientation": "Landscape"
|
||||
}
|
||||
```
|
||||
|
||||
### 3. Subsequent Requests (With Auth Token)
|
||||
```
|
||||
GET {server_url}/api/playlists/{player_id}
|
||||
Header: Authorization: Bearer {auth_code}
|
||||
```
|
||||
|
||||

|
||||
|
||||
## The Problem with Self-Signed Certificates
|
||||
|
||||
When a player tries to connect to a server with a self-signed certificate:
|
||||
|
||||
```
|
||||
SSL/TLS Handshake:
|
||||
✓ Server presents self-signed certificate
|
||||
✗ requests library validates against system CA store
|
||||
✗ Self-signed cert NOT in system CA store
|
||||
✗ Connection rejected with SSLError
|
||||
|
||||
Result: Player fails to authenticate → Player is offline
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## How to Enable Self-Signed Certificate Support
|
||||
|
||||
### Quickest Fix (Development/Testing Only)
|
||||
⚠️ **NOT RECOMMENDED FOR PRODUCTION**
|
||||
|
||||
Disable certificate verification in all requests:
|
||||
```python
|
||||
response = requests.post(url, ..., verify=False) # Dangerous!
|
||||
```
|
||||
|
||||
### Proper Fix (Production-Ready)
|
||||
|
||||
#### Step 1: Export server's certificate
|
||||
```bash
|
||||
# From the server with self-signed cert
|
||||
openssl s_client -connect server.local:443 -showcerts < /dev/null | \
|
||||
openssl x509 -outform PEM > ca_bundle.crt
|
||||
```
|
||||
|
||||
#### Step 2: Place certificate in player
|
||||
```bash
|
||||
cp ca_bundle.crt /path/to/Kiwy-Signage/config/ca_bundle.crt
|
||||
```
|
||||
|
||||
#### Step 3: Modify player code to use it
|
||||
|
||||
Create `src/ssl_config.py`:
|
||||
```python
|
||||
import os
|
||||
|
||||
class SSLConfig:
|
||||
@staticmethod
|
||||
def get_verify_setting():
|
||||
"""Get SSL verification setting"""
|
||||
custom_ca = 'config/ca_bundle.crt'
|
||||
if os.path.exists(custom_ca):
|
||||
return custom_ca
|
||||
return True # System default
|
||||
```
|
||||
|
||||
Modify `src/player_auth.py`:
|
||||
```python
|
||||
from ssl_config import SSLConfig
|
||||
|
||||
class PlayerAuth:
|
||||
def __init__(self, config_file='player_auth.json'):
|
||||
self.config_file = config_file
|
||||
self.auth_data = self._load_auth_data()
|
||||
self.verify_ssl = SSLConfig.get_verify_setting()
|
||||
|
||||
def authenticate(self, ...):
|
||||
response = requests.post(
|
||||
auth_url,
|
||||
json=payload,
|
||||
timeout=timeout,
|
||||
verify=self.verify_ssl # ← ADD THIS
|
||||
)
|
||||
|
||||
# Repeat for: verify_auth(), get_playlist(),
|
||||
# send_heartbeat(), send_feedback()
|
||||
```
|
||||
|
||||
Modify `src/get_playlists_v2.py`:
|
||||
```python
|
||||
from ssl_config import SSLConfig
|
||||
|
||||
def download_media_files(playlist, media_dir):
|
||||
verify_ssl = SSLConfig.get_verify_setting()
|
||||
for media in playlist:
|
||||
response = requests.get(
|
||||
file_url,
|
||||
timeout=30,
|
||||
verify=verify_ssl # ← ADD THIS
|
||||
)
|
||||
```
|
||||
|
||||

|
||||
|
||||
## Configuration Files
|
||||
|
||||
### Player Configuration (read by player)
|
||||
**File:** `config/app_config.json`
|
||||
```json
|
||||
{
|
||||
"server_ip": "digi-signage.moto-adv.com",
|
||||
"port": "443",
|
||||
"screen_name": "tv-terasa",
|
||||
"quickconnect_key": "8887779",
|
||||
"orientation": "Landscape",
|
||||
"touch": "True",
|
||||
"max_resolution": "1920x1080",
|
||||
"edit_feature_enabled": true
|
||||
}
|
||||
```
|
||||
|
||||
**⚠️ Note:** No SSL/certificate options available
|
||||
|
||||
### Player Auth (saved after first connection)
|
||||
**File:** `src/player_auth.json` (or configured path)
|
||||
```json
|
||||
{
|
||||
"hostname": "tv-terasa",
|
||||
"auth_code": "eyJhbGc...",
|
||||
"player_id": 42,

## SSL Error Troubleshooting
|
||||
|
||||
### Error: `certificate verify failed`
|
||||
**Cause:** Server has self-signed certificate
|
||||
**Solution:** Export and use CA bundle (see "Proper Fix" above)
|
||||
|
||||
### Error: `SSLError: [SSL: CERTIFICATE_VERIFY_FAILED]`
|
||||
**Cause:** Same as above
|
||||
**Solution:** Add `verify=ca_bundle_path` to requests calls
|
||||
|
||||
### Error: `Cannot connect to server` (generic)
|
||||
**Cause:** Could be SSL error caught by try-except
|
||||
**Solution:** Check logs, enable debug mode, test with `curl`:
|
||||
```bash
|
||||
curl -v https://server:443/api/health
|
||||
```
|
||||
|
||||
### Works with `curl -k` but fails with player
|
||||
**Cause:** Player has certificate verification, curl doesn't
|
||||
**Solution:** Use proper CA certificate instead of `-k` flag
|
||||
|
||||
---
|
||||
|
||||
## Testing
|
||||
|
||||
### Test Current Behavior
|
||||
```bash
|
||||
cd /tmp/Kiwy-Signage
|
||||
python3 -c "
|
||||
import sys
|
||||
sys.path.insert(0, 'src')
|
||||
from player_auth import PlayerAuth
|
||||
|
||||
auth = PlayerAuth()
|
||||
success, error = auth.authenticate(
|
||||
server_url='https://server.local:443',
|
||||
hostname='test-player',
|
||||
quickconnect_code='TEST123'
|
||||
)
|
||||
print(f'Result: {success}, Error: {error}')
|
||||
"
|
||||
```
|
||||
|
||||
### Test With Custom CA
|
||||
```bash
|
||||
# After implementing ssl_config.py:
|
||||
export REQUESTS_CA_BUNDLE=/path/to/ca_bundle.crt
|
||||
cd /tmp/Kiwy-Signage
|
||||
python3 src/main.py
|
||||
```
|
||||

|
||||
## Recommended Next Steps
|
||||
|
||||
1. ✅ Review this analysis
|
||||
2. ✅ Decide between:
|
||||
- Using `verify=False` (quick, insecure)
|
||||
- Implementing custom CA support (proper, secure)
|
||||
- Sticking with production certs (safest)
|
||||
3. ✅ If using custom CA:
|
||||
- Export certificate from your DigiServer
|
||||
- Place in `config/ca_bundle.crt`
|
||||
- Implement changes from "Proper Fix" section
|
||||
4. ✅ Test with both production and self-signed servers
|
||||
5. ✅ Document in player README

openssl s_client -connect localhost:443 -showcerts < /dev/null | \
|
||||
openssl x509 -outform PEM > /tmp/server_cert.crt
|
||||
|
||||
# Copy to player configuration directory
|
||||
# (transfer via SSH, USB, or other secure method)
|
||||
cp /tmp/server_cert.crt /path/to/Kiwy-Signage/config/ca_bundle.crt
|
||||
|
||||
# Verify it was copied correctly
|
||||
ls -la /path/to/Kiwy-Signage/config/ca_bundle.crt
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## PATCH 5: Alternative - Use Environment Variable
|
||||
|
||||
Instead of placing cert in config directory, you can use environment variable:
|
||||
|
||||
```bash
|
||||
#!/bin/bash
|
||||
# Before running the player:
|
||||
|
||||
export REQUESTS_CA_BUNDLE=/etc/ssl/certs/custom-ca.crt
|
||||
cd /path/to/Kiwy-Signage
|
||||
./start.sh
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Testing After Patches
|
||||
|
||||
### Test 1: Verify patches applied correctly
|
||||
|
||||
```bash
|
||||
cd /tmp/Kiwy-Signage/src
|
||||
|
||||
# Check imports added
|
||||
grep "from ssl_config import SSLConfig" player_auth.py
|
||||
grep "from ssl_config import SSLConfig" get_playlists_v2.py
|
||||
|
||||
# Check verify parameter added
|
||||
grep "verify=self.verify_ssl" player_auth.py | wc -l
|
||||
# Should output: 5
|
||||
|
||||
# Check new file exists
|
||||
test -f ssl_config.py && echo "ssl_config.py exists" || echo "MISSING"
|
||||
```
|
||||
|
||||
### Test 2: Test with self-signed server
|
||||
|
||||
```bash
|
||||
cd /tmp/Kiwy-Signage
|
||||
|
||||
# 1. Export server cert (run on server)
|
||||
openssl s_client -connect server.local:443 -showcerts < /dev/null | \
|
||||
openssl x509 -outform PEM > config/ca_bundle.crt
|
||||
|
||||
# 2. Test player connection
|
||||
python3 -c "
|
||||
import sys
|
||||
sys.path.insert(0, 'src')
|
||||
from player_auth import PlayerAuth
|
||||
from ssl_config import SSLConfig
|
||||
|
||||
# Check what certificate will be used
|
||||
cert_path = SSLConfig.get_ca_bundle()
|
||||
print(f'Using certificate: {cert_path}')
|
||||
|
||||
# Try authentication
|
||||
auth = PlayerAuth()
|
||||
success, error = auth.authenticate(
|
||||
server_url='https://server.local:443',
|
||||
hostname='test-player',
|
||||
quickconnect_code='TEST123'
|
||||
)
|
||||
print(f'Connection result: {\"SUCCESS\" if success else \"FAILED\"}')
|
||||
if error:
|
||||
print(f'Error: {error}')
|
||||
"
|
||||
```
|
||||
|
||||
### Test 3: Verify backward compatibility
|
||||
|
||||
```bash
|
||||
cd /tmp/Kiwy-Signage
|
||||
|
||||
# Test connection to production server (valid CA cert)
|
||||
python3 -c "
|
||||
import sys
|
||||
sys.path.insert(0, 'src')
|
||||
from player_auth import PlayerAuth
|
||||
|
||||
auth = PlayerAuth()
|
||||
success, error = auth.authenticate(
|
||||
server_url='https://digi-signage.moto-adv.com',
|
||||
hostname='test-player',
|
||||
quickconnect_code='TEST123'
|
||||
)
|
||||
print(f'Production server: {\"OK\" if success else \"FAILED\"}')
|
||||
"

# Player HTTPS Connection Issues - Analysis & Solutions
|
||||
|
||||
## Problem Summary
|
||||
Players can successfully connect to the DigiServer when using **HTTP on port 80**, but connections are **refused/blocked when the server is on HTTPS**.
|
||||
|
||||
---
|
||||
|
||||
## Root Causes Identified
|
||||
|
||||
### 1. **Missing CORS Headers on API Endpoints** ⚠️ CRITICAL
|
||||
**Issue:** The app imports `Flask-Cors` (requirements.txt line 31) but **never initializes it** in the application.
|
||||
|
||||
**Location:**
|
||||
- [app/extensions.py](app/extensions.py) - CORS not initialized
|
||||
- [app/app.py](app/app.py#L1-L80) - No CORS initialization in create_app()
|
||||
|
||||
**Impact:** Players making cross-origin requests (from device IP to server domain/IP) get CORS errors and connections are refused at the browser/HTTP client level.
|
||||
|
||||
**Affected Endpoints:**
|
||||
- `/api/playlists` - GET (primary endpoint for player playlist fetch)
|
||||
- `/api/auth/player` - POST (authentication)
|
||||
- `/api/auth/verify` - POST (token verification)
|
||||
- `/api/player-feedback` - POST (player status updates)
|
||||
- All endpoints prefixed with `/api/*`
|
||||
|
||||
---
|
||||
|
||||
### 2. **SSL Certificate Trust Issues** ⚠️ CRITICAL for Device-to-Server Communication
|
||||
|
||||
**Issue:** Players are likely receiving **self-signed certificates** from nginx.
|
||||
|
||||
**Location:**
|
||||
- [docker-compose.yml](docker-compose.yml#L22-L35) - Nginx container with SSL
|
||||
- [nginx.conf](nginx.conf#L54-L67) - SSL certificate paths point to self-signed certs
|
||||
- [data/nginx-ssl/](data/nginx-ssl/) - Contains `cert.pem` and `key.pem`
|
||||
|
||||
**Details:**
|
||||
```
|
||||
ssl_certificate /etc/nginx/ssl/cert.pem;
|
||||
ssl_certificate_key /etc/nginx/ssl/key.pem;
|
||||
```
|
||||
|
||||
**Impact:**
|
||||
- Players using standard HTTP clients (Python `requests`, JavaScript `fetch`, Kivy's HTTP module) will **reject self-signed certificates by default**
|
||||
- This causes connection refusal with SSL certificate verification errors
|
||||
- The player might be using hardcoded certificate verification (certificate pinning)
|
||||
|
||||
---
|
||||
|
||||
### 3. **No Certificate Validation Bypass in Player API** ⚠️ HIGH
|
||||
|
||||
**Issue:** The API endpoints don't provide a way for players to bypass SSL verification or explicitly trust the certificate.
|
||||
|
||||
**What's Missing:**
|
||||
```python
|
||||
# Players likely need:
|
||||
# - Endpoint to fetch and validate server certificate
|
||||
# - API response with certificate fingerprint
|
||||
# - Configuration to disable cert verification for self-signed setups
|
||||
# - Or: Generate proper certificates with Let's Encrypt
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### 4. **Potential HTTP/HTTPS Redirect Issues**
|
||||
|
||||
**Location:** [nginx.conf](nginx.conf#L40-L50)
|
||||
|
||||
**Issue:** HTTP requests to "/" are redirected to HTTPS:
|
||||
```nginx
|
||||
location / {
|
||||
return 301 https://$host$request_uri; # Forces HTTPS
|
||||
}
|
||||
```
|
||||
|
||||
**Impact:**
|
||||
- If player tries to connect via HTTP, it gets a 301 redirect to HTTPS
|
||||
- If the player doesn't follow redirects or isn't configured for HTTPS, it fails
|
||||
- The redirect URL depends on the `$host` variable, which might not match player's expectations
|
||||
|
||||
---
|
||||
|
||||
### 5. **ProxyFix Middleware May Lose Protocol Info**
|
||||
|
||||
**Location:** [app/app.py](app/app.py#L37)
|
||||
|
||||
**Issue:**
|
||||
```python
|
||||
app.wsgi_app = ProxyFix(app.wsgi_app, x_for=1, x_proto=1, x_host=1, x_port=1)
|
||||
```
|
||||
|
||||
**Detail:** If nginx doesn't properly set `X-Forwarded-Proto: https`, the app might generate HTTP URLs in responses instead of HTTPS.
|
||||
|
||||
**Config Check:**
|
||||
```nginx
|
||||
proxy_set_header X-Forwarded-Proto $scheme; # Should be in nginx.conf
|
||||
```
|
||||
|
||||
✓ **This is present in nginx.conf**, so ProxyFix should work correctly.
|
||||
|
||||
---
|
||||
|
||||
### 6. **Security Headers Might Block Requests**
|
||||
|
||||
**Location:** [nginx.conf](nginx.conf#L70-L74)
|
||||
|
||||
**Issue:**
|
||||
```nginx
|
||||
add_header X-Frame-Options "SAMEORIGIN" always;
|
||||
add_header Content-Security-Policy "default-src 'self' http: https: data: blob: 'unsafe-inline'" always;
|
||||
```
|
||||
|
||||
**Impact:** Overly restrictive CSP could block embedded resource loading from players.
|
||||
|
||||
---
|
||||
|
||||
### 7. **Missing Player Certificate Configuration** ⚠️ CRITICAL
|
||||
|
||||
**Issue:** Players (especially embedded devices) often have:
|
||||
- Limited certificate stores
|
||||
- Self-signed cert validation disabled by default in some frameworks
|
||||
- No built-in mechanism to trust new certificates
|
||||
|
||||
**What's Not Addressed:**
|
||||
- No endpoint to retrieve server certificate for device installation
|
||||
- No configuration for certificate thumbprint verification
|
||||
- No setup guide for device SSL configuration
|
||||
|
||||
---
|
||||
|
||||
## Solutions by Priority
|
||||
|
||||
### 🔴 **PRIORITY 1: Enable CORS for API Endpoints**
|
||||
|
||||
**Fix:** Initialize Flask-CORS in the application.
|
||||
|
||||
**File:** [app/extensions.py](app/extensions.py)
|
||||
```python
|
||||
from flask_cors import CORS
|
||||
|
||||
# Add after other extensions
|
||||
```
|
||||
|
||||
**File:** [app/app.py](app/app.py) - In `create_app()` function
|
||||
```python
|
||||
# After initializing extensions, add:
|
||||
CORS(app, resources={
|
||||
r"/api/*": {
|
||||
"origins": ["*"], # Or specific origins: ["http://...", "https://..."]
|
||||
"methods": ["GET", "POST", "OPTIONS"],
|
||||
"allow_headers": ["Content-Type", "Authorization"],
|
||||
"supports_credentials": True,
|
||||
"max_age": 3600
|
||||
}
|
||||
})
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### 🔴 **PRIORITY 2: Fix SSL Certificate Issues**
|
||||
|
||||
**Option A: Use Let's Encrypt (Recommended for production)**
|
||||
```bash
|
||||
# Generate proper certificates with certbot
|
||||
certbot certonly --standalone -d yourdomain.com --email your@email.com
|
||||
```
|
||||
|
||||
**Option B: Generate Self-Signed Certs with Longer Validity**
|
||||
```bash
|
||||
# Current certs might be expired or have trust issues
|
||||
openssl req -x509 -newkey rsa:4096 -keyout key.pem -out cert.pem -days 365 \
|
||||
-subj "/CN=digiserver/O=Organization/C=US"
|
||||
```
|
||||
|
||||
**Option C: Allow Players to Trust Self-Signed Cert**
|
||||
|
||||
Add endpoint to serve certificate:
|
||||
```python
|
||||
# In app/blueprints/api.py
|
||||
|
||||
@api_bp.route('/certificate', methods=['GET'])
|
||||
def get_server_certificate():
|
||||
"""Return server certificate for player installation."""
|
||||
try:
|
||||
with open('/etc/nginx/ssl/cert.pem', 'r') as f:
|
||||
cert_content = f.read()
|
||||
|
||||
return jsonify({
|
||||
'certificate': cert_content,
|
||||
'certificate_format': 'PEM'
|
||||
}), 200
|
||||
except Exception as e:
|
||||
return jsonify({'error': str(e)}), 500
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### 🟡 **PRIORITY 3: Update Configuration**
|
||||
|
||||
**File:** [app/config.py](app/config.py)
|
||||
|
||||
**Change:**
|
||||
```python
|
||||
# Line 28 - Currently set to False for development
|
||||
SESSION_COOKIE_SECURE = False # Set to True in production with HTTPS
|
||||
```
|
||||
|
||||
**To:**
|
||||
```python
|
||||
class ProductionConfig(Config):
|
||||
SESSION_COOKIE_SECURE = True # HTTPS only
|
||||
SESSION_COOKIE_SAMESITE = 'Lax'
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### 🟡 **PRIORITY 4: Fix nginx Configuration**
|
||||
|
||||
**Verify in [nginx.conf](nginx.conf):**
|
||||
```nginx
|
||||
# Line 86-95: Ensure these headers are present
|
||||
proxy_set_header X-Forwarded-Proto $scheme;
|
||||
proxy_set_header X-Forwarded-Host $server_name;
|
||||
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
|
||||
|
||||
# Add this for player connections:
|
||||
proxy_set_header X-Forwarded-Port 443;
|
||||
```
|
||||
|
||||
**Consider relaxing CORS headers at nginx level:**
|
||||
```nginx
|
||||
# Add to location / block in HTTPS server:
|
||||
add_header 'Access-Control-Allow-Origin' '*' always;
|
||||
add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS' always;
|
||||
add_header 'Access-Control-Allow-Headers' 'Content-Type, Authorization' always;
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### 🟡 **PRIORITY 5: Update Player Connection Code**
|
||||
|
||||
**If you control the player code, add:**
|
||||
|
||||
```python
|
||||
# Python example for player connecting to server
|
||||
import requests
|
||||
from requests.adapters import HTTPAdapter
|
||||
from requests.packages.urllib3.util.retry import Retry
|
||||
|
||||
class PlayerClient:
|
||||
def __init__(self, server_url, hostname, quickconnect_code, verify_ssl=False):
|
||||
self.server_url = server_url
|
||||
self.session = requests.Session()
|
||||
|
||||
# For self-signed certs, disable verification (NOT RECOMMENDED for production)
|
||||
self.session.verify = verify_ssl
|
||||
|
||||
# Or: Trust specific certificate
|
||||
# self.session.verify = '/path/to/server-cert.pem'
|
||||
|
||||
self.hostname = hostname
|
||||
self.quickconnect_code = quickconnect_code
|
||||
|
||||
def get_playlist(self):
|
||||
"""Fetch playlist from server."""
|
||||
try:
|
||||
response = self.session.get(
|
||||
f"{self.server_url}/api/playlists",
|
||||
params={
|
||||
'hostname': self.hostname,
|
||||
'quickconnect_code': self.quickconnect_code
|
||||
},
|
||||
headers={'Authorization': f'Bearer {self.auth_code}'}
|
||||
)
|
||||
response.raise_for_status()
|
||||
return response.json()
|
||||
except requests.exceptions.SSLError as e:
|
||||
print(f"SSL Error: {e}")
|
||||
# Retry without SSL verification if configured
|
||||
if not self.session.verify:
|
||||
raise
|
||||
# Fall back to unverified connection
|
||||
self.session.verify = False
|
||||
return self.get_playlist()
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Verification Steps
|
||||
|
||||
### Test 1: Check CORS Headers
|
||||
```bash
|
||||
# This should include Access-Control-Allow-Origin
|
||||
curl -v https://192.168.0.121/api/health -H "Origin: *"
|
||||
```
|
||||
|
||||
### Test 2: Check SSL Certificate
|
||||
```bash
|
||||
# View certificate details
|
||||
openssl s_client -connect 192.168.0.121:443 -showcerts
|
||||
|
||||
# Check expiration
|
||||
openssl x509 -in /srv/digiserver-v2/data/nginx-ssl/cert.pem -text -noout | grep -i valid
|
||||
```
|
||||
|
||||
### Test 3: Test API Endpoint
|
||||
```bash
|
||||
# Try fetching playlist (should fail with SSL error or CORS error initially)
|
||||
curl -k https://192.168.0.121/api/playlists \
|
||||
-G --data-urlencode "hostname=test" \
|
||||
--data-urlencode "quickconnect_code=test123" \
|
||||
-H "Origin: http://192.168.0.121"
|
||||
```
|
||||
|
||||
### Test 4: Player Connection Simulation
|
||||
```python
|
||||
# From player device
|
||||
import requests
|
||||
session = requests.Session()
|
||||
session.verify = False # Temp for testing
|
||||
|
||||
response = session.get(
|
||||
'https://192.168.0.121/api/playlists',
|
||||
params={'hostname': 'player1', 'quickconnect_code': 'abc123'}
|
||||
)
|
||||
print(response.json())
|
||||
```
|
||||

## Summary of Changes Needed
|
||||
|
||||
| Issue | Fix | Priority | File |
|
||||
|-------|-----|----------|------|
|
||||
| No CORS Headers | Initialize Flask-CORS | 🔴 HIGH | app/extensions.py, app/app.py |
|
||||
| Self-Signed SSL Cert | Get Let's Encrypt cert or add trust endpoint | 🔴 HIGH | data/nginx-ssl/ |
|
||||
| Certificate Validation | Add /certificate endpoint | 🟡 MEDIUM | app/blueprints/api.py |
|
||||
| SESSION_COOKIE_SECURE | Update in ProductionConfig | 🟡 MEDIUM | app/config.py |
|
||||
| X-Forwarded Headers | Verify nginx.conf | 🟡 MEDIUM | nginx.conf |
|
||||
| CSP Too Restrictive | Relax CSP for player requests | 🟢 LOW | nginx.conf |
|
||||
|
||||
---
|
||||
|
||||
## Quick Fix for Immediate Testing
|
||||
|
||||
To quickly test if CORS is the issue:
|
||||
|
||||
1. **Enable CORS temporarily:**
|
||||
```bash
|
||||
docker exec digiserver-v2 python -c "
|
||||
from app import create_app
|
||||
from flask_cors import CORS
|
||||
app = create_app('production')
|
||||
CORS(app)
|
||||
"
|
||||
```
|
||||
|
||||
2. **Test player connection:**
|
||||
```bash
|
||||
curl -k https://192.168.0.121/api/health
|
||||
```
|
||||
|
||||
3. **If works, the issue is CORS + SSL certificates**

# Implementation Summary - HTTPS Player Connection Fixes
|
||||
|
||||
## ✅ Completed Implementations
|
||||
|
||||
### 1. **CORS Support - FULLY IMPLEMENTED** ✓
|
||||
- **Status**: VERIFIED and WORKING
|
||||
- **Evidence**: CORS headers present on all API responses
|
||||
- **What was done**:
|
||||
- Added Flask-CORS import to [app/extensions.py](app/extensions.py)
|
||||
- Initialized CORS in [app/app.py](app/app.py) with configuration for `/api/*` endpoints
|
||||
- Configured CORS for all HTTP methods: GET, POST, PUT, DELETE, OPTIONS
|
||||
- Headers being returned successfully:
|
||||
```
|
||||
access-control-allow-origin: *
|
||||
access-control-allow-methods: GET, POST, PUT, DELETE, OPTIONS
|
||||
access-control-allow-headers: Content-Type, Authorization
|
||||
access-control-max-age: 3600
|
||||
```
|
||||
|
||||
### 2. **Production HTTPS Configuration** ✓
|
||||
- **Status**: IMPLEMENTED
|
||||
- **What was done**:
|
||||
- Updated [app/config.py](app/config.py) ProductionConfig:
|
||||
- Set `SESSION_COOKIE_SECURE = True` for HTTPS-only cookies
|
||||
- Set `SESSION_COOKIE_SAMESITE = 'Lax'` to allow CORS requests with credentials
|
||||
|
||||
### 3. **Nginx CORS and SSL Headers** ✓
|
||||
- **Status**: IMPLEMENTED and VERIFIED
|
||||
- **What was done**:
|
||||
- Updated [nginx.conf](nginx.conf) with:
|
||||
- CORS headers at nginx level for all responses
|
||||
- OPTIONS request handling (CORS preflight)
|
||||
- X-Forwarded-Port header forwarding
|
||||
- Proper SSL/TLS configuration (TLS 1.2 and 1.3)
|
||||
|
||||
### 4. **Certificate Endpoint** ⚠️
|
||||
- **Status**: Added (routing issue being debugged)
|
||||
- **What was done**:
|
||||
- Added `/api/certificate` GET endpoint in [app/blueprints/api.py](app/blueprints/api.py)
|
||||
- Serves server certificate in PEM format for device trust configuration
|
||||
- Includes certificate metadata parsing with optional cryptography support
|
||||
- **Note**: Route appears not to register - likely Flask-CORS or app context issue
|
||||

## 📊 Test Results
|
||||
|
||||
### ✅ CORS Headers - VERIFIED
|
||||
```bash
|
||||
$ curl -v -k https://192.168.0.121/api/playlists
|
||||
|
||||
< HTTP/2 400
|
||||
< access-control-allow-origin: *
|
||||
< access-control-allow-methods: GET, POST, PUT, DELETE, OPTIONS
|
||||
< access-control-allow-headers: Content-Type, Authorization
|
||||
< access-control-max-age: 3600
|
||||
```
|
||||
|
||||
### ✅ Health Endpoint
|
||||
```bash
|
||||
$ curl -s -k https://192.168.0.121/api/health | jq .
|
||||
{
|
||||
"status": "healthy",
|
||||
"timestamp": "2026-01-16T20:02:13.177245",
|
||||
"version": "2.0.0"
|
||||
}
|
||||
```
|
||||
|
||||
### ✅ HTTPS Working
|
||||
```bash
|
||||
$ curl -v -k https://192.168.0.121/api/health
|
||||
< HTTP/2 200
|
||||
< SSL connection using TLSv1.3 / TLS_AES_256_GCM_SHA384
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 🔍 What This Fixes
|
||||
|
||||
### **Before Implementation**
|
||||
- ❌ Players get CORS errors on HTTPS
|
||||
- ❌ Browsers/HTTP clients block cross-origin API requests
|
||||
- ❌ SSL/HTTPS security headers missing at app level
|
||||
- ❌ Sessions insecure on HTTPS
|
||||
- ❌ Proxy headers not properly forwarded
|
||||
|
||||
### **After Implementation**
|
||||
- ✅ CORS headers present on all API responses
|
||||
- ✅ Players can make cross-origin requests from any origin
|
||||
- ✅ Preflight OPTIONS requests handled
|
||||
- ✅ Cookies properly secured with HTTPS/SAMESITE flags
|
||||
- ✅ X-Forwarded-* headers forwarded for protocol detection
|
||||
- ✅ HTTPS with TLS 1.2 and 1.3 support

## 🎯 Critical Issues Resolved
|
||||
|
||||
| Issue | Status | Solution |
|
||||
|-------|--------|----------|
|
||||
| **CORS Blocking Requests** | ✅ FIXED | Flask-CORS enabled with wildcard origins |
|
||||
| **Cross-Origin Preflight Fail** | ✅ FIXED | OPTIONS requests handled at nginx + Flask |
|
||||
| **Session Insecurity over HTTPS** | ✅ FIXED | SESSION_COOKIE_SECURE set |
|
||||
| **CORS Credentials Blocked** | ✅ FIXED | SESSION_COOKIE_SAMESITE = 'Lax' |
|
||||
| **Protocol Detection Failure** | ✅ FIXED | X-Forwarded headers in nginx |
|
||||
|
||||
---
|
||||
|
||||
## ⚠️ Remaining Tasks
|
||||
|
||||
### Certificate Endpoint (Lower Priority)
|
||||
The `/api/certificate` endpoint for serving self-signed certificates needs debugging. This is for enhanced compatibility with devices that need certificate trust configuration. **Workaround**: Players can fetch certificate directly from nginx at port 443.
|
||||
|
||||
### Next Steps for Players
|
||||
1. Update player code to handle HTTPS (see PLAYER_HTTPS_INTEGRATION_GUIDE.md)
|
||||
2. Optionally implement SSL certificate verification with server cert
|
||||
3. Test playlist fetching on HTTPS
|
||||
|
||||

|
||||
|
||||
## 🧪 Verification Commands
|
||||
|
||||
Test that CORS is working:
|
||||
```bash
|
||||
# Should return CORS headers
|
||||
curl -i -k https://192.168.0.121/api/health
|
||||
|
||||
# Test preflight request
|
||||
curl -X OPTIONS -H "Origin: *" \
|
||||
https://192.168.0.121/api/playlists -v
|
||||
|
||||
# Test with credentials
|
||||
curl -k https://192.168.0.121/api/playlists \
|
||||
--data-urlencode "hostname=test" \
|
||||
--data-urlencode "quickconnect_code=test123"
|
||||
```

## Required Player Code Changes
|
||||
|
||||
### 1. **For Python/Kivy Players Using Requests Library**
|
||||
|

```
|
||||
|
||||
### 2. **For Kivy Framework Specifically**
|
||||
|
||||
**Update:** In your Kivy HTTP client configuration:
|
||||
|
||||
```python
|
||||
from kivy.network.urlrequest import UrlRequest
|
||||
from kivy.logger import Logger
|
||||
import ssl
|
||||
import certifi
|
||||
|
||||
class DigiServerKivyClient:
|
||||
def __init__(self, server_url, hostname, quickconnect_code):
|
||||
self.server_url = server_url
|
||||
self.hostname = hostname
|
||||
self.quickconnect_code = quickconnect_code
|
||||
|
||||
# Configure SSL context for Kivy requests
|
||||
self.ssl_context = self._setup_ssl_context()
|
||||
|
||||
def _setup_ssl_context(self):
|
||||
"""Setup SSL context with certificate trust."""
|
||||
try:
|
||||
# Try to get server certificate
|
||||
import requests
|
||||
response = requests.get(
|
||||
f"{self.server_url}/api/certificate",
|
||||
verify=False,
|
||||
timeout=5
|
||||
)
|
||||
|
||||
if response.status_code == 200:
|
||||
cert_data = response.json()
|
||||
cert_path = os._get_cert_path()
|
||||
|
||||
with open(cert_path, 'w') as f:
|
||||
f.write(cert_data['certificate'])
|
||||
|
||||
# Create SSL context
|
||||

|
||||
context.load_verify_locations(cert_path)
|
||||
|
||||
Logger.info('DigiServer', f'SSL context configured with server certificate')
|
||||
return context
|
||||
|
||||
except Exception as e:
|
||||
Logger.warning('DigiServer', f'Failed to setup SSL: {e}')
|
||||
return None
|
||||
|
||||

|
||||
|
||||
headers = {
|
||||
'Content-Type': 'application/json',
|
||||
'User-Agent': 'Kiwy-Signage-Player/1.0'
|
||||
}
|
||||
|
||||
request = UrlRequest(
|
||||
url + params,
|
||||
on_success=callback,
|
||||
on_error=self._on_error,
|
||||
on_failure=self._on_failure,
|
||||
headers=headers
|
||||
)
|
||||
|
||||
return request
|
||||
|
||||

def _on_failure(self, request, result):
|
||||
Logger.error('DigiServer', f'Request failed: {result}')
|
||||
```
|
||||
|
||||
### 3. **Environment Configuration**
|
||||
|
||||
**Add to player app_config.json or environment:**
|
||||
|
||||
```json
|
||||
{
|
||||
"server": {
|
||||
"url": "https://192.168.0.121",
|
||||
"hostname": "player1",
|
||||
"quickconnect_code": "ABC123XYZ",
|
||||
"verify_ssl": false,
|
||||
"use_server_certificate": true,
|
||||
"certificate_path": "~/.digiserver/server_cert.pem"
|
||||
},
|
||||
"connection": {
|
||||
"timeout": 10,
|
||||
"retry_attempts": 3,
|
||||
"retry_delay": 5
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Testing Checklist
|
||||
|
||||
### Server-Side Tests
|
||||
|
||||
- [ ] Verify CORS headers present: `curl -v https://192.168.0.121/api/health`
|
||||
- [ ] Check certificate endpoint: `curl -k https://192.168.0.121/api/certificate`
|
||||
- [ ] Test OPTIONS preflight: `curl -X OPTIONS https://192.168.0.121/api/playlists`
|
||||
- [ ] Verify X-Forwarded headers: `curl -v https://192.168.0.121/`
|
||||
|
||||
### Player Connection Tests
|
||||
|
||||
- [ ] Player connects with HTTPS successfully
|
||||
- [ ] Player fetches playlist without SSL errors
|
||||
- [ ] Player receives status update confirmation
|
||||
- [ ] Player sends feedback/heartbeat correctly
|
||||
|
||||
### Integration Tests
|
||||
|
||||
```bash
|
||||
# Test certificate retrieval
|
||||
curl -k https://192.168.0.121/api/certificate | jq '.certificate_info'
|
||||
|
||||
# Test CORS preflight for player
|
||||
curl -X OPTIONS https://192.168.0.121/api/playlists \
|
||||
-H "Origin: http://192.168.0.121" \
|
||||
-H "Access-Control-Request-Method: GET" \
|
||||
-v
|
||||
|
||||
# Simulate player playlist fetch
|
||||
curl -k https://192.168.0.121/api/playlists \
|
||||
--data-urlencode "hostname=test-player" \
|
||||
--data-urlencode "quickconnect_code=test123" \
|
||||
-H "Origin: *"
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Migration Steps
|
||||
|
||||
### For Existing Players
|
||||
|
||||
1. **Update player code** with new SSL handling from this guide
|
||||
2. **Restart player application** to pick up changes
|
||||
3. **Verify connection** works with HTTPS server
|
||||
4. **Monitor logs** for any SSL-related errors
|
||||
|
||||
### For New Players
|
||||
|
||||
1. **Deploy updated player code** with SSL support from the start
|
||||
2. **Configure with HTTPS server URL**
|
||||
3. **Run initialization** to fetch and trust server certificate
|
||||
|
||||
---
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### "SSL: CERTIFICATE_VERIFY_FAILED"
|
||||
- Player is rejecting the self-signed certificate
|
||||
- **Solution**: Run certificate trust setup or disable SSL verification
|
||||
|
||||
### "Connection Refused"
|
||||
- Server HTTPS port not accessible
|
||||
- **Solution**: Check nginx is running, port 443 is open, firewall rules
|
||||
|
||||
### "CORS error"
|
||||
- Browser/HTTP client blocking cross-origin request
|
||||
- **Solution**: Verify CORS headers in response, check Origin header
|
||||
|
||||
### "Certificate not found at endpoint"
|
||||
- Server certificate file missing
|
||||
- **Solution**: Verify cert.pem exists at `/etc/nginx/ssl/cert.pem`
|
||||
|
||||
---
|
||||
|
||||
## Security Recommendations
|
||||
|
||||
1. **For Development/Testing**: Disable SSL verification temporarily
|
||||
```python
|
||||
session.verify = False
|
||||
```
|
||||
|
||||
2. **For Production**:
|
||||
- Use proper certificates (Let's Encrypt recommended)
|
||||
- Deploy certificate trust setup at player initialization
|
||||
- Monitor SSL certificate expiration
|
||||
- Implement certificate pinning for critical deployments
|
||||
|
||||
3. **For Self-Signed Certificates**:
|
||||
- Use `/api/certificate` endpoint to distribute certificates
|
||||
- Store certificates in secure location on device
|
||||
- Implement certificate update mechanism
|
||||
- Log certificate trust changes for auditing

## Next Steps
|
||||
|
||||
1. **Implement SSL handling** in player code using examples above
|
||||
2. **Test with HTTP first** to ensure API works
|
||||
3. **Enable HTTPS** and test with certificate handling
|
||||
4. **Deploy to production** with proper SSL setup
|
||||
5. **Monitor** player connections and SSL errors
