All Implemented Interfaces:

CryptoAlgorithm, AbstractGetNonceSize

public class SymmetricCryptorConfigAes
extends SymmetricCryptorConfig

SecurityCryptorAlgorithmSymmetricConfig for AES.
Attention: JCA/JCE is buggy (creates a nonce of 12 on encryption but expects 16 bytes nonce on decryption, etc.). Therefore you shall only use this with BouncyCastle.

Since:

1.0.0
