## ⚠️ ISSUES REQUIRING ATTENTION
### Issue #1: Hardcoded Default Values in Config 🔴
**Location**: `app/config.py`
**Problem**:
```python
SECRET_KEY = os.getenv('SECRET_KEY', 'dev-secret-key-change-in-production')
DEFAULT_ADMIN_PASSWORD = os.getenv('ADMIN_PASSWORD', 'Initial01!')
```
**Risk**: Default values will be used if environment variables not set
**Solution** (Choose one):
**Option A: Remove defaults (Recommended)**
```python
SECRET_KEY = os.getenv('SECRET_KEY') # Fails fast if not set
DEFAULT_ADMIN_PASSWORD = os.getenv('ADMIN_PASSWORD')
```
**Option B: Use stronger defaults**
```python
import secrets
SECRET_KEY = os.getenv('SECRET_KEY', secrets.token_urlsafe(32))
DEFAULT_ADMIN_PASSWORD = os.getenv('ADMIN_PASSWORD', secrets.token_urlsafe(16))
```
---
### Issue #2: Uncommitted Changes 🟡
**Current status**: 7 uncommitted changes
```
M app/app.py (CORS implementation)
M app/blueprints/api.py (Certificate endpoint)
M app/config.py (Session security)
M app/extensions.py (CORS support)
M nginx.conf (CORS headers)
M requirements.txt (Added cryptography)
? old_code_documentation/ (New documentation)
```
**Action Required**:
```bash
cd /srv/digiserver-v2
git add -A
git commit -m "HTTPS improvements: Enable CORS, fix player connections, add security headers"
git log --oneline -1

1. **Read the main analysis:** Start with [KIWY_PLAYER_HTTPS_ANALYSIS.md](./KIWY_PLAYER_HTTPS_ANALYSIS.md)
2. **Review your requirements:** Decide if you need self-signed certificate support
3. **Plan implementation:** Use [KIWY_PLAYER_ARCHITECTURE_DIAGRAM.md](./KIWY_PLAYER_ARCHITECTURE_DIAGRAM.md) for deployment scenarios
4. **Apply patches:** Follow [KIWY_PLAYER_SSL_PATCHES.md](./KIWY_PLAYER_SSL_PATCHES.md) step by step
5. **Test thoroughly:** Verify with both production and self-signed servers
6. **Deploy:** Roll out to player devices and monitor logs

## Deployment Scenarios
### Scenario 1: Production Server (Current)
```
DigiServer v2
(digi-signage.moto-adv.com)
│
│ Valid CA Certificate
│ (e.g., Let's Encrypt)
│
▼
Player (No patches needed)
│
▼ requests.post/get(..., timeout=30)
├─ No verify= specified
└─ Uses system default: verify=True
│
▼ validates cert ✓
│
▼ SSL handshake succeeds ✓
│
▼ authenticated ✓
Result: ✅ Works fine (no changes needed)
```
---
### Scenario 2: Self-Signed Server (After Patches)
```
DigiServer v2 (self.local)
(Self-signed certificate)
│
│ 1. Export cert
│ openssl s_client... > server.crt
│
│ 2. Place in player
│ config/ca_bundle.crt
│
▼
Player (with patches)
│
▼ __init__()
│
▼ SSLConfig.get_verify_setting()
├─ Check custom CA: None
├─ Check env var: not set
├─ Check config dir: ✓ found ca_bundle.crt
│
└─ Return: 'config/ca_bundle.crt'
│
▼ requests.post/get(..., verify='config/ca_bundle.crt')
│
▼ validates cert against ca_bundle.crt ✓
│
▼ SSL handshake succeeds ✓
│
▼ authenticated ✓
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
```
---

**Responsibility:** Stores server IP, port, player credentials, and settings
---
## 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)
#### 2. **Playlist Fetching** (src/player_auth.py)
**Location:** [Line 178](../../tmp/Kiwy-Signage/src/player_auth.py#L178)
```python
response = requests.get(playlist_url, headers=headers, timeout=timeout)
```
- **URL:** `{server_url}/api/playlists/{player_id}`
- **Method:** GET
- **Auth:** Bearer token in Authorization header
- **Headers:** `Authorization: Bearer {auth_code}`
- **SSL Verify:** DEFAULT (True, **NO `verify=` parameter**)
#### 3. **Heartbeat/Status** (src/player_auth.py)
**Location:** [Line 227](../../tmp/Kiwy-Signage/src/player_auth.py#L227)
```python
response = requests.post(heartbeat_url, headers=headers, json=payload, timeout=timeout)
```
- **URL:** `{server_url}/api/players/{player_id}/heartbeat`
- **Method:** POST
- **Auth:** Bearer token
- **SSL Verify:** DEFAULT (True, **NO `verify=` parameter**)
#### 4. **Player Feedback** (src/player_auth.py)
**Location:** [Line 254](../../tmp/Kiwy-Signage/src/player_auth.py#L254)
```python
response = requests.post(feedback_url, headers=headers, json=payload, timeout=timeout)
```
- **URL:** `{server_url}/api/player-feedback`
- **Method:** POST
- **Auth:** Bearer token
- **SSL Verify:** DEFAULT (True, **NO `verify=` parameter**)
#### 5. **Media Download** (src/get_playlists_v2.py)
**Location:** [Line 159](../../tmp/Kiwy-Signage/src/get_playlists_v2.py#L159)
```python
response = requests.get(file_url, timeout=30)
```
- **URL:** Direct to media file URLs from playlist
- **Method:** GET
- **Auth:** None (public download URLs)
- **SSL Verify:** DEFAULT (True, **NO `verify=` parameter**)
---
## 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
```

## 8. Summary Table
| Aspect | Current State | Support Level |
|--------|---------------|----------------|
| **HTTP Client** | requests 2.32.4 | ✅ Production-ready |
| **HTTPS Support** | Yes (standard URLs) | ✅ Full |
| **Self-Signed Certs** | ❌ NO | ❌ NOT SUPPORTED |
| **Custom CA Bundle** | ❌ NO | ❌ NOT SUPPORTED |
| **Certificate Pinning** | ❌ NO | ❌ NOT SUPPORTED |
| **SSL Verify Parameter** | Default (True) | ⚠️ All requests use default |
| **Hardcoded Settings** | None | - |
| **Environment Variables** | Not checked | ⚠️ Could be added |
| **Configuration File** | app_config.json (no SSL options) | ⚠️ Could be extended |
---
## 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:
```
src/player_auth.py:
Line 95: requests.post(auth_url, json=payload, timeout=timeout)
Line 157: requests.post(verify_url, json=payload, timeout=timeout)
Line 178: requests.get(playlist_url, headers=headers, timeout=timeout)
Line 227: requests.post(heartbeat_url, headers=headers, json=payload, timeout=timeout)
Line 254: requests.post(feedback_url, headers=headers, json=payload, timeout=timeout)
src/get_playlists_v2.py:
Line 159: requests.get(file_url, timeout=30)
working_files/test_direct_api.py:
Line 32: requests.get(url, headers=headers, timeout=10)
working_files/get_playlists.py:
Line 101: requests.post(feedback_url, json=feedback_data, timeout=10)
Line 131: requests.get(server_url, params=params)
Line 139: requests.get(file_url, timeout=10)
```
All calls use default `verify=True` (implicit).
---
## 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

# Kiwy-Signage HTTPS Configuration - Quick Reference
## Quick Facts
| Item | Value |
|------|-------|
| **HTTP Client Library** | `requests` v2.32.4 |
| **Self-Signed Cert Support** | ❌ NO (requires code changes) |
| **Custom CA Bundle Support** | ❌ NO (requires code changes) |
| **Certificate Verification** | ✅ Enabled by default (requests default behavior) |
| **Lines of Code Making HTTPS Requests** | 6 locations across 2 files |
---
## Where HTTPS Requests Are Made
### Core Authentication (player_auth.py)
```python
# LINE 95: Initial authentication
response = requests.post(auth_url, json=payload, timeout=timeout)
# LINE 157: Auth verification
response = requests.post(verify_url, json=payload, timeout=timeout)
# LINE 178: Get playlist
response = requests.get(playlist_url, headers=headers, timeout=timeout)
# LINE 227: Send heartbeat
response = requests.post(heartbeat_url, headers=headers, json=payload, timeout=timeout)
# LINE 254: Send feedback
response = requests.post(feedback_url, headers=headers, json=payload, timeout=timeout)
```
### Media Downloads (get_playlists_v2.py)
```python
# LINE 159: Download media file
response = requests.get(file_url, timeout=30)
```
---
## 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,
"player_name": "TV-Terasa",
"playlist_id": 100,
"orientation": "Landscape",
"authenticated": true,
"server_url": "https://digi-signage.moto-adv.com:443"
}
```

## 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
```
---
## Summary of Changes Needed
| File | Changes | Lines |
|------|---------|-------|
| `src/ssl_config.py` | **CREATE NEW** - SSL config class | ~20 lines |
| `src/player_auth.py` | Add `verify_ssl` to `__init__` | +1 line |

| `config/app_config.json` | Optional: Add `ca_bundle_path` key | +1 line |
| `config/ca_bundle.crt` | **CREATE** - From server cert | - |
**Total Code Changes:** ~8 modified lines + 1 new file (20 lines)
**Backward Compatible:** Yes
**Breaking Changes:** None
---
## 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

# 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())
```

---
## 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**
---
## Recommended Next Steps
1. ✅ Enable Flask-CORS in the application
2. ✅ Generate/obtain proper SSL certificates (Let's Encrypt recommended)
3. ✅ Add certificate trust endpoint for devices
4. ✅ Update nginx configuration for player device compatibility
5. ✅ Create player connection guide documenting HTTPS setup

```
---
## 🔍 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

## 📝 Files Modified
1. **app/extensions.py** - Added `from flask_cors import CORS`
2. **app/app.py** - Initialized CORS with API endpoint configuration
3. **app/config.py** - Added `SESSION_COOKIE_SAMESITE = 'Lax'`
4. **nginx.conf** - Added CORS headers and OPTIONS handling
5. **requirements.txt** - Added `cryptography==42.0.7`
6. **app/blueprints/api.py** - Added certificate endpoint (partial)
---
## 🎯 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**
**Update:** Import and use certificate handling:
```python
import requests
from requests.adapters import HTTPAdapter
from requests.packages.urllib3.util.retry import Retry
import os
class DigiServerClient:
def __init__(self, server_url, hostname, quickconnect_code, use_https=True):
self.server_url = server_url
self.hostname = hostname
self.quickconnect_code = quickconnect_code
self.session = requests.Session()
# CRITICAL: Handle SSL verification
if use_https:
# Option 1: Get certificate from server and trust it
self.setup_certificate_trust()
else:
# Option 2: Disable SSL verification (DEV ONLY)
self.session.verify = False
def setup_certificate_trust(self):
"""Download server certificate and configure trust."""
try:
# First, make a request without verification to get the cert
response = requests.get(
f"{self.server_url}/api/certificate",
verify=False,
timeout=5
)
if response.status_code == 200:
cert_data = response.json()
# Save certificate locally
cert_path = os.path.expanduser('~/.digiserver/server_cert.pem')
os.makedirs(os.path.dirname(cert_path), exist_ok=True)
with open(cert_path, 'w') as f:
f.write(cert_data['certificate'])
# Configure session to use this certificate
self.session.verify = cert_path
print(f"✓ Server certificate installed from {cert_data['certificate_info']['issuer']}")
print(f" Valid until: {cert_data['certificate_info']['valid_until']}")
except Exception as e:
print(f"⚠️ Failed to setup certificate trust: {e}")
print(" Falling back to unverified connection (not recommended for production)")
self.session.verify = False
def get_playlist(self):
"""Get playlist from server with proper error handling."""
try:
response = self.session.get(
f"{self.server_url}/api/playlists",
params={
'hostname': self.hostname,
'quickconnect_code': self.quickconnect_code
},
timeout=10
)
response.raise_for_status()
return response.json()
except requests.exceptions.SSLError as e:
print(f"❌ SSL Error: {e}")
# Log error for debugging
print(" This usually means the server certificate is not trusted.")
print(" Try running: DigiServerClient.setup_certificate_trust()")
raise
except requests.exceptions.ConnectionError as e:
print(f"❌ Connection Error: {e}")
raise
except Exception as e:
print(f"❌ Error: {e}")
raise
def send_feedback(self, status, message=''):
"""Send player feedback/status to server."""
try:
response = self.session.post(
f"{self.server_url}/api/player-feedback",
json={
'hostname': self.hostname,
'quickconnect_code': self.quickconnect_code,
'status': status,
'message': message,
'timestamp': datetime.utcnow().isoformat()
},
timeout=10
)
response.raise_for_status()
return response.json()
except Exception as e:
print(f"Error sending feedback: {e}")
return None
```
### 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 = ssl.create_default_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
def fetch_playlist(self, callback):
"""Fetch playlist with proper SSL handling."""
url = f"{self.server_url}/api/playlists"
params = f"?hostname={self.hostname}&quickconnect_code={self.quickconnect_code}"
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_error(self, request, error):
Logger.error('DigiServer', f'Request error: {error}')
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
