EcdhEs class

A class for ECDH-ES key derivation

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

Constructors

EcdhEs({required Uint8List algId, required Uint8List apu, required Uint8List apv}): Constructs an instance of EcdhEs.

algId → Uint8List: final
apu → Uint8List: final
apv → Uint8List: final
hashCode → int: The hash code for this object.
no setterinherited
runtimeType → Type: A representation of the runtime type of the object.

decryptDirect({required KeyAlgorithm encryptionAlgorithm, required Key recipientKey, required Uint8List ciphertext, required Key ephemeralKey, 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 recipientKey, required bool receive}) → Key: Derives an ECDH-ES shared key for anonymous encryption.
encryptDirect({required KeyAlgorithm encryptionAlgorithm, required Key recipientKey, required Key ephemeralKey, 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.

receiverUnwrapKey({required KeyAlgorithm keyWrappingAlgorithm, required KeyAlgorithm encryptionAlgorithm, required Key ephemeralKey, required Key recipientKey, required Uint8List ciphertext, Uint8List? nonce, Uint8List? tag}) → Key: Unwraps a key for the receiver using the derived key.
senderWrapKey({required KeyAlgorithm keyWrappingAlgorithm, required Key ephemeralKey, required Key recipientKey, required Key cek}) → EncryptedBuffer: Wraps a key for the sender using the derived key.
toString() → String: A string representation of this object.
