asymmetric static method

IAsymmetricCipher asymmetric(
  1. CryptoAlgorithm algorithm,
  2. InputAsymmetricCipher input
)

Creates an asymmetric cipher based on the given algorithm.

algorithm: The asymmetric cipher algorithm (RSA, ECDSA) input: The complete input record with configuration

Returns: An instance of the specified asymmetric cipher

Throws: ArgumentError if algorithm is not supported

Note: ECDSA is supported only as signature, not as cipher.

Implementation

static IAsymmetricCipher asymmetric(
  CryptoAlgorithm algorithm,
  InputAsymmetricCipher input,
) {
  return switch (algorithm) {
    CryptoAlgorithm.rsa => RSACipher.createFull(InputRSACipher(parent: input)),
    CryptoAlgorithm.ecdsa => throw ArgumentError(
      'ECDSA is not supported as a cipher. Use asymmetricSign() for signature operations.',
    ),
    _ => throw ArgumentError('Not an asymmetric cipher algorithm: $algorithm'),
  };
}
