public class Cipher:

Cipher

High-level encryption facade inspired by Java `Cipher`. This class is intentionally focused on encryption and decryption. Hashing, MACs, signatures, random generation and key derivation are exposed by dedicated classes such as `MessageDigest`, `Mac`, `Signature`, `SecureRandom`, `KeyGenerator`, `KeyPairGenerator` and `SecretKeyFactory`. Supported features: - AES encryption/decryption in `GCM`, `CBC` and `CTR` - RSA encryption/decryption in `OAEP` and `PKCS1`

import klyn.cryptography

keyGenerator = AESKeyGenerator()
keyGenerator.initialize(256)
key = keyGenerator.generateKey()
payload = Cipher.aesGcmEncrypt("secret", key)
plain = Cipher.aesGcmDecrypt(payload, key)
print(plain)
