)Biometric Signature
Create cryptographic signatures using device biometrics with keys stored in Secure Enclave (iOS/macOS), StrongBox/Keystore (Android), and TPM (Windows).
Bank-Grade Security. Developer-Friendly API.
Hardware Security
Keys are generated and stored in Secure Enclave (iOS/macOS) and StrongBox/Keystore (Android). Private keys never leave the secure hardware.
Cryptographic Signatures
Create RSA-2048 or ECDSA (P-256) signatures that your backend can independently verify. True proof of identity.
ECIES Decryption
Decrypt sensitive data using hybrid ECIES encryption with X9.63 key derivation, SHA-256, and AES-GCM.
Biometric Authentication
Seamless integration with FaceID, TouchID, and Android BiometricPrompt. Native UI on every platform.
Key Invalidation
Optionally invalidate keys when biometric enrollment changes. Detect if fingerprints or Face ID have been modified.
Device Credential Fallback
Allow PIN, pattern, or password fallback on Android when biometrics are unavailable.

- ✓Platform-specific configuration options
- ✓Comprehensive error handling
- ✓Backend examples in Node.js, Python & Go
// Create biometric-protected keys
final result = await BiometricSignature()
.createKeys(
enforceBiometric: true,
promptMessage: "Authenticate to register",
);
if (result != null) {
// Send public key to your backend
await api.registerPublicKey(result.publicKey);
}// Sign a challenge from your server
final signature = await BiometricSignature()
.createSignature(
options: SignatureOptions(
payload: serverChallenge,
promptMessage: "Confirm transaction",
),
);
// Send signature to backend for verification
