senderWrapKey method

EncryptedBuffer senderWrapKey({
  1. required KeyAlgorithm keyWrappingAlgorithm,
  2. required Key ephemeralKey,
  3. required Key recipientKey,
  4. required Key senderKey,
  5. required Key cek,
  6. required Uint8List ccTag,
})

Wraps a key for the sender using the derived key.

Returns an EncryptedBuffer containing the wrapped key.

Implementation

EncryptedBuffer senderWrapKey({
  required KeyAlgorithm keyWrappingAlgorithm,
  required Key ephemeralKey,
  required Key recipientKey,
  required Key senderKey,
  required Key cek,
  required Uint8List ccTag,
}) {
  final derived = deriveKey(
    encryptionAlgorithm: keyWrappingAlgorithm,
    ephemeralKey: ephemeralKey,
    recipientKey: recipientKey,
    senderKey: senderKey,
    receive: false,
    ccTag: ccTag,
  );
  final encryptedBuffer = derived.wrapKey(other: cek);
  derived.handle.free();
  return encryptedBuffer;
