CipherFactory class

Central factory for creating cipher, signature, and key exchange instances.

This factory provides a centralized way to instantiate cryptographic objects based on algorithm enums. It eliminates the need to remember specific class names and provides a consistent API across all cipher types.

Usage

// Create symmetric cipher
final aes = CipherFactory.symmetric(
  SymmetricCipherAlgorithmEnum.aes,
  InputSymmetricCipher(
    parent: (...),
    key: AESCipher.generateKey(),
  ),
);

// Create asymmetric cipher
final rsa = CipherFactory.asymmetric(
  AsymmetricCipherAlgorithmEnum.rsa,
  InputAsymmetricCipher(
    parent: (...),
    publicKey: '...',
    privateKey: '...',
  ),
);

// Create signature
final hmac = CipherFactory.symmetricSign(
  SymmetricSignAlgorithmEnum.hmac,
  InputSymmetricSign(
    parent: (...),
    key: HMACSign.generateKey(),
  ),
);
