+# SOCKS5 Proxy Support Patch for Session Desktop
+
+This patch adds full SOCKS5 proxy support to Session Desktop, allowing all application traffic (including onion requests) to be routed through a SOCKS proxy server.
+
+## Features
+
+- ✅ SOCKS5 proxy support with authentication
+- ✅ Proper timeout handling for proxy connections (30s vs 5s for direct)
+- ✅ TLS/SSL certificate validation through proxy
+- ✅ Certificate pinning preservation
+- ✅ Agent caching for performance optimization
+- ✅ Detailed error logging for debugging
+- ✅ UI for proxy configuration in Settings
+- ✅ Auto-updater disabled when proxy is enabled (prevents traffic leaks)
+
+## Changes Summary
+
+### Critical Changes (Required for functionality)
+
+1. **InsecureNodeFetch.ts** - Core proxy implementation
+   - `SocksProxyAgentWithTls` class for TLS options propagation
+   - Proxy agent priority over sslAgent
+   - TLS options extraction from original agent
+   - Agent caching with TLS configuration support
+
+2. **SeedNodeAPI.ts** - Timeout adjustment
+   - Increased timeout from 5s to 30s when proxy is enabled
+
+3. **onionPath.ts** - Timeout adjustment
+   - Increased timeout from 10s to 30s when proxy is enabled
+
+### Optional Improvements
+
+4. **Enhanced error logging** - Better debugging capabilities
+5. **Patch stamp tracking** - Version verification tool
+6. **Agent caching** - Performance optimization
+
+## Security Considerations
+
+- TLS settings are extracted from the original `sslAgent` and preserved through the proxy
+- Certificate pinning continues to work through SOCKS proxy
+- `rejectUnauthorized` is only set to `false` if it was already disabled in the original agent
+- No security regression for production seed nodes
+- **Auto-updater is disabled when proxy is enabled** to prevent traffic leaks
+  - electron-updater uses native HTTP clients that bypass our proxy configuration
+  - Users must update manually when using proxy mode
+  - This ensures 100% traffic routing through proxy with no leaks
+
+## Installation
+
+### Apply the patch:
+
+```bash
+cd ~/Nextcloud/WORKSPACE/PROJECTS/session-desktop
+git apply socks-proxy-support.patch
+```
+
+### Build and install:
+
+```bash
+# Build the application
+PATH=~/.nvm/versions/node/v20.18.2/bin:/bin:/usr/bin:$PATH npx yarn build
+
+# Build release package
+PATH=~/.nvm/versions/node/v20.18.2/bin:/bin:/usr/bin:$PATH \
+  NODE_OPTIONS='--max-old-space-size=8192' \
+  npx yarn build-release
+
+# Install the package
+sudo dpkg -i release/session-desktop-linux-amd64-1.17.5.deb
+```
+
+## Usage
+
+1. Open Session Desktop
+2. Go to **Settings** → **Proxy**
+3. Enable proxy and configure:
+   - **Proxy Server**: Your SOCKS5 proxy address (e.g., 192.168.1.254)
+   - **Port**: SOCKS5 proxy port (e.g., 1080)
+   - **Username** (optional): For authenticated proxies
+   - **Password** (optional): For authenticated proxies
+4. Click **Save**
+
+**⚠️ Important Notes:**
+- **Auto-updates are disabled** when proxy is enabled to prevent traffic leaks
+- To update Session Desktop while using proxy, download new version manually from GitHub Releases
+- All application traffic (messages, media, metadata) routes through proxy
+- Disable proxy to re-enable auto-updates
+
+## Testing
+
+To verify the proxy is working, check the logs:
+
+```bash
+tail -f ~/.config/Session/logs/app.log | grep -i "proxy"
+```
+
+You should see:
+- `Creating new SOCKS5 agent` on first connection
+- `Using cached agent` on subsequent connections
+- No `self signed certificate` errors
+- Successful connections through proxy
+
+## Files Modified
+
+- `ts/session/utils/InsecureNodeFetch.ts` - Core proxy logic
+- `ts/session/apis/seed_node_api/SeedNodeAPI.ts` - Timeout adjustment
+- `ts/session/onions/onionPath.ts` - Timeout adjustment
+- `ts/components/dialog/user-settings/pages/ProxySettingsPage.tsx` - UI component
+- `ts/data/settings-key.ts` - Proxy settings keys
+- `ts/state/ducks/modalDialog.tsx` - Modal state
+- `_locales/en/messages.json` - Localization strings
+- `_locales/ru/messages.json` - Russian localization
+- `package.json` - Dependencies (socks-proxy-agent, etc.)
+
+## Dependencies Added
+
+- `socks-proxy-agent` - SOCKS5 proxy support
+- `socks` - SOCKS protocol implementation
+- `smart-buffer` - Buffer utilities for SOCKS
+
+## Troubleshooting
+
+### Timeouts after 30 seconds
+- Check if your SOCKS proxy is accessible
+- Verify proxy address and port are correct
+- Test proxy with curl: `curl --socks5 host:port https://example.com`
+
+### Self-signed certificate errors
+- Ensure you're not using a local devnet with custom certificates
+- Check if the issue occurs without proxy (to isolate the problem)
+
+### Connection works without proxy but fails with proxy
+- Verify SOCKS5 proxy supports HTTPS/TLS connections
+- Check proxy logs for connection attempts
+- Enable debug logging in Session to see detailed errors
