Functions

generateX25519EphemeralKeyPair() → Future<(List<int>, List<int>)>

Generates a X25519 ephemeral key pair. Returns a Future that completes with a tuple containing the private key and the public key.

jwkFromSharedKey(List<int> sharedKey) → Map<String, dynamic>

Converts a shared key to a JWK (JSON Web Key) representation. Returns the JWK.

makeSharedKey(List<int> privateKey, List<int> publicKey) → Future<List<int>>

Makes a 32-byte shared key from the private key and the public key. Returns a Future that completes with the shared key.

privateKeyfromX25519Jwk(Map<String, dynamic> jwk) → List<int>

Converts a X25519 JWK (JSON Web Key) to a X25519 private key. Returns the X25519 private key.

publicKeyfromX25519Jwk(Map<String, dynamic> jwk) → List<int>

Converts a X25519 JWK (JSON Web Key) to a X25519 public key. Returns the X25519 public key.

x25519JwkFromEd25519PrivateKey(List<int> privateKey) → Future<Map<String, dynamic>>

Converts an Ed25519 private key to a X25519 private key and then to a JWK (JSON Web Key) representation. Returns a Future that completes with the JWK.

x25519JwkFromEd25519PublicKey(List<int> publicKey) → Map<String, dynamic>

Converts an Ed25519 public key to a X25519 public key and then to a JWK (JSON Web Key) representation. Returns the JWK.

x25519JwkFromX25519PrivateKey(List<int> privateKey) → Future<Map<String, dynamic>>
