decryptFile method

List<int> decryptFile(
  1. List<int> bytes, {
  2. CipherKey? cipherKey,
  3. Keyset? keyset,
  4. String? using,
})

Decrypts file content in bytes format.

Provide cipherKey to override Keyset.cipherKey.

If keyset is not provided, then it tries to obtain a keyset using name. If that fails, then it uses the default keyset. If that fails as well, then it will throw InvariantException.

Implementation

List<int> decryptFile(List<int> bytes,
    {CipherKey? cipherKey, Keyset? keyset, String? using}) {
  if (cipherKey != null) {
    return _core.crypto.decryptFileData(cipherKey, bytes);
  }
  keyset ??= _core.keysets[using];
  return keyset.cipherKey == _core.keysets.defaultKeyset.cipherKey
      ? _core.crypto.decrypt(bytes)
      : _core.crypto.decryptFileData(keyset.cipherKey!, bytes);
}
