Ecdh1PU class

A class for ECDH-1PU key derivation

This class provides methods to derive shared keys for authenticated encryption and to perform direct encryption and decryption using the derived keys.

Methods

decryptDirect({required KeyAlgorithm encryptionAlgorithm, required Key recipientKey, required Key ephemeralKey, required Key senderKey, required Uint8List ciphertext, required Uint8List nonce, required Uint8List tag, Uint8List? aad}) → Uint8List
Decrypts a message directly using the derived key.
deriveKey({required KeyAlgorithm encryptionAlgorithm, required Key ephemeralKey, required Key senderKey, required Key recipientKey, required bool receive, Uint8List? ccTag}) → Key
Derives an ECDH-1PU shared key for authenticated encryption.
encryptDirect({required KeyAlgorithm encryptionAlgorithm, required Key recipientKey, required Key ephemeralKey, required Key senderKey, required Uint8List message, Uint8List? aad, Uint8List? nonce}) → EncryptedBuffer
Encrypts a message directly using the derived key.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
