Static Methods

generateKeyPair() → ({Uint8List publicKey, Uint8List secretKey})
Generates a fresh P-256 key pair.
publicKeyFromPrivate(Uint8List privateKey) Uint8List
Derives the uncompressed SEC1 public key (0x04 || X || Y) for the 32-byte private scalar privateKey as d · G.
sign({required Uint8List privateKey, required Uint8List message}) Uint8List
Signs message with privateKey (a 32-byte scalar), returning r || s.
verify({required Uint8List publicKey, required Uint8List message, required Uint8List signature}) bool
Verifies a raw r || s signature over message under publicKey.

Constants

privateKeyBytes → const int
Private scalar length in bytes.
publicKeyBytes → const int
Uncompressed SEC1 public-key length in bytes (0x04 || X || Y).
signatureBytes → const int
Raw r || s signature length in bytes.
