# Location Sharing Library
|
||||
|
||||
## Overview
|
||||
|
||||
Core C++ library for live GPS location sharing with zero-knowledge end-to-end encryption in Organic Maps.
|
||||
|
||||
## Features
|
||||
|
||||
- **AES-256-GCM Encryption**: Industry-standard authenticated encryption
|
||||
- **Zero-knowledge architecture**: Server never sees encryption keys
|
||||
- **Cross-platform**: Linux/Android (OpenSSL), iOS/macOS (CommonCrypto), Windows (BCrypt)
|
||||
- **Automatic session management**: UUID generation, key derivation, URL encoding
|
||||
- **Update scheduling**: Configurable intervals with automatic throttling
|
||||
- **Battery protection**: Auto-stop below threshold
|
||||
- **Dual modes**: Standalone GPS or navigation with ETA/distance
|
||||
|
||||
## Components
|
||||
|
||||
### 1. Types (`location_sharing_types.hpp/cpp`)
|
||||
|
||||
**SessionCredentials:**
|
||||
```cpp
|
||||
SessionCredentials creds = SessionCredentials::Generate();
|
||||
std::string shareUrl = creds.GenerateShareUrl("https://server.com");
|
||||
```
|
||||
|
||||
**LocationPayload:**
|
||||
```cpp
|
||||
LocationPayload payload(gpsInfo);
|
||||
payload.mode = SharingMode::Navigation;
|
||||
payload.eta = timestamp + timeToArrival;
|
||||
std::string json = payload.ToJson();
|
||||
```
|
||||
|
||||
**EncryptedPayload:**
|
||||
```cpp
|
||||
EncryptedPayload encrypted;
|
||||
encrypted.iv = "..."; // 12 bytes base64
|
||||
encrypted.ciphertext = "...";
|
||||
encrypted.authTag = "..."; // 16 bytes base64
|
||||
std::string json = encrypted.ToJson();
|
||||
```
|
||||
|
||||
### 2. Encryption (`crypto_util.hpp/cpp`)
|
||||
|
||||
**Encrypt:**
|
||||
```cpp
|
||||
std::string key = "base64-encoded-32-byte-key";
|
||||
std::string plaintext = "{...}";
|
||||
auto encrypted = crypto::EncryptAes256Gcm(key, plaintext);
|
||||
if (encrypted.has_value()) {
|
||||
std::string json = encrypted->ToJson();
|
||||
// Send to server
|
||||
}
|
||||
```
|
||||
|
||||
**Decrypt:**
|
||||
```cpp
|
||||
auto decrypted = crypto::DecryptAes256Gcm(key, encryptedPayload);
|
||||
if (decrypted.has_value()) {
|
||||
// Process plaintext
|
||||
}
|
||||
```
|
||||
|
||||
**Platform implementations:**
|
||||
- **OpenSSL** (Android/Linux): `EVP_aes_256_gcm()` with `EVP_CIPHER_CTX`
|
||||
- **CommonCrypto** (iOS/macOS): TODO - currently placeholder, needs Security framework
|
||||
- **BCrypt** (Windows): TODO - currently placeholder
|
||||
|
||||
### 3. Session Management (`location_sharing_session.hpp/cpp`)
|
||||
|
||||
**Basic usage:**
|
||||
```cpp
|
||||
LocationSharingSession session;
|
||||
|
||||
// Set callbacks
|
||||
session.SetPayloadReadyCallback([](EncryptedPayload const & payload) {
|
||||
// Send to server
|
||||
PostToServer(payload.ToJson());
|
||||
});
|
||||
|
||||
// Start session
|
||||
SessionConfig config;
|
||||
config.updateIntervalSeconds = 20;
|
||||
SessionCredentials creds = session.Start(config);
|
||||
std::string shareUrl = creds.GenerateShareUrl("https://server.com");
|
||||
|
||||
// Update location
|
||||
session.UpdateLocation(gpsInfo);
|
||||
|
||||
// Update navigation (optional)
|
||||
session.UpdateNavigationInfo(eta, distance, "Destination Name");
|
||||
|
||||
// Update battery
|
||||
session.UpdateBatteryLevel(85);
|
||||
|
||||
// Stop session
|
||||
session.Stop();
|
||||
```
|
||||
|
||||
**State machine:**
|
||||
- `Inactive` → `Starting` → `Active` → `Stopping` → `Inactive`
|
||||
- `Error` state on failures
|
||||
|
||||
**Callbacks:**
|
||||
```cpp
|
||||
session.SetStateChangeCallback([](SessionState state) {
|
||||
LOG(LINFO, ("State:", static_cast<int>(state)));
|
||||
});
|
||||
|
||||
session.SetErrorCallback([](std::string const & error) {
|
||||
LOG(LERROR, ("Error:", error));
|
||||
});
|
||||
```
|
||||
|
||||
## Building
|
||||
|
||||
### CMake
|
||||
|
||||
```cmake
|
||||
add_subdirectory(libs/location_sharing)
|
||||
|
||||
target_link_libraries(your_target
|
||||
PRIVATE
|
||||
location_sharing
|
||||
)
|
||||
```
|
||||
|
||||
### Dependencies
|
||||
|
||||
**Linux/Android:**
|
||||
```bash
|
||||
sudo apt-get install libssl-dev
|
||||
```
|
||||
|
||||
**iOS/macOS:**
|
||||
- Security framework (automatic)
|
||||
|
||||
**Windows:**
|
||||
- BCrypt (automatic)
|
||||
|
||||
### Android NDK
|
||||
|
||||
OpenSSL is typically bundled or available via:
|
||||
```gradle
|
||||
android {
|
||||
externalNativeBuild {
|
||||
cmake {
|
||||
arguments "-DOPENSSL_ROOT_DIR=/path/to/openssl"
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Security
|
||||
|
||||
### Encryption Details
|
||||
|
||||
- **Algorithm**: AES-256-GCM (Galois/Counter Mode)
|
||||
- **Key size**: 256 bits (32 bytes)
|
||||
- **IV size**: 96 bits (12 bytes) - recommended for GCM
|
||||
- **Auth tag size**: 128 bits (16 bytes)
|
||||
- **Key generation**: `SecRandomCopyBytes` (iOS) or `std::random_device` fallback
|
||||
|
||||
### URL Format
|
||||
|
||||
```
|
||||
https://server.com/live/{base64url(sessionId:encryptionKey)}
|
||||
```
|
||||
|
||||
Example:
|
||||
```
|
||||
https://live.organicmaps.app/live/YWJjZDEyMzQtNTY3OC05MGFiLWNkZWYtMTIzNDU2Nzg5MGFiOmFiY2RlZmdoaWprbG1ub3BxcnN0dXZ3eHl6MTIzNDU2Nzg
|
||||
```
|
||||
|
||||
Decoded:
|
||||
```
|
||||
abcd1234-5678-90ab-cdef-1234567890ab:abcdefghijklmnopqrstuvwxyz12345678
|
||||
^
|
||||
separator
|
||||
```
|
||||
|
||||
### Zero-Knowledge Architecture
|
||||
|
||||
1. **Client** generates session ID (UUID) + 256-bit key
|
||||
2. **Client** encrypts location with key
|
||||
3. **Server** stores encrypted blob (no key access)
|
||||
4. **Share URL** contains both session ID and key
|
||||
5. **Viewer** decrypts in-browser using key from URL
|
||||
|
||||
**Server NEVER sees:**
|
||||
- Encryption key
|
||||
- Plaintext location data
|
||||
- User identity (session ID is random UUID)
|
||||
|
||||
### Threat Model
|
||||
|
||||
**Protected against:**
|
||||
- Server compromise (data is encrypted)
|
||||
- Man-in-the-middle (TLS + authenticated encryption)
|
||||
- Replay attacks (timestamp in payload)
|
||||
- Tampering (GCM authentication tag)
|
||||
|
||||
**NOT protected against:**
|
||||
- URL interception (anyone with URL can decrypt)
|
||||
- Client compromise (key is in memory)
|
||||
- Quantum computers (AES-256 is quantum-resistant)
|
||||
|
||||
## Testing
|
||||
|
||||
### Unit Tests
|
||||
|
||||
```cpp
|
||||
// Test encryption round-trip
|
||||
TEST(CryptoUtil, EncryptDecrypt) {
|
||||
std::string key = GenerateRandomKey();
|
||||
std::string plaintext = "test data";
|
||||
|
||||
auto encrypted = crypto::EncryptAes256Gcm(key, plaintext);
|
||||
ASSERT_TRUE(encrypted.has_value());
|
||||
|
||||
auto decrypted = crypto::DecryptAes256Gcm(key, *encrypted);
|
||||
ASSERT_TRUE(decrypted.has_value());
|
||||
EXPECT_EQ(plaintext, *decrypted);
|
||||
}
|
||||
|
||||
// Test auth tag validation
|
||||
TEST(CryptoUtil, AuthTagValidation) {
|
||||
auto encrypted = crypto::EncryptAes256Gcm(key, plaintext);
|
||||
encrypted->authTag[0] ^= 0xFF; // Corrupt tag
|
||||
|
||||
auto decrypted = crypto::DecryptAes256Gcm(key, *encrypted);
|
||||
EXPECT_FALSE(decrypted.has_value()); // Should fail
|
||||
}
|
||||
```
|
||||
|
||||
### Integration Tests
|
||||
|
||||
See `docs/LOCATION_SHARING_INTEGRATION.md` for full testing guide.
|
||||
|
||||
## Performance
|
||||
|
||||
### Benchmarks (approximate)
|
||||
|
||||
- **Encryption**: ~1-5 ms for 200-byte payload (hardware-dependent)
|
||||
- **Memory**: ~100 bytes per session
|
||||
- **Network**: ~300-400 bytes per update (encrypted + JSON overhead)
|
||||
|
||||
### Optimization Tips
|
||||
|
||||
1. **Reuse sessions**: Don't create new session per update
|
||||
2. **Batch updates**: If sending multiple locations, consider batching
|
||||
3. **Adjust intervals**: Increase `updateIntervalSeconds` for better battery life
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### OpenSSL linking errors (Android/Linux)
|
||||
|
||||
```
|
||||
undefined reference to `EVP_EncryptInit_ex`
|
||||
```
|
||||
|
||||
**Solution:**
|
||||
```cmake
|
||||
find_package(OpenSSL REQUIRED)
|
||||
target_link_libraries(location_sharing PRIVATE OpenSSL::SSL OpenSSL::Crypto)
|
||||
```
|
||||
|
||||
### CommonCrypto not found (iOS)
|
||||
|
||||
**Solution:**
|
||||
```cmake
|
||||
find_library(SECURITY_FRAMEWORK Security)
|
||||
target_link_libraries(location_sharing PRIVATE ${SECURITY_FRAMEWORK})
|
||||
```
|
||||
|
||||
### Encryption fails at runtime
|
||||
|
||||
**Check:**
|
||||
1. Key is exactly 32 bytes (base64-decoded)
|
||||
2. IV is 12 bytes
|
||||
3. Auth tag is 16 bytes
|
||||
4. Platform crypto library is available
|
||||
|
||||
**Debug logging:**
|
||||
```cpp
|
||||
#define LOG_CRYPTO_ERRORS
|
||||
```
|
||||
|
||||

## Contributing
|
||||
|
||||
When adding features:
|
||||
1. Maintain zero-knowledge architecture
|
||||
2. Add unit tests for crypto changes
|
