AesBytesEncryptor

public AesBytesEncryptor(javax.crypto.SecretKey secretKey,
                         BytesKeyGenerator ivGenerator,
                         AesBytesEncryptor.CipherAlgorithm alg)

Constructs an encryptor that uses AES encryption.

Parameters:

secretKey - the secret (symmetric) key

ivGenerator - the generator used to generate the initialization vector. If null, then a default algorithm will be used based on the provided AesBytesEncryptor.CipherAlgorithm

alg - the AesBytesEncryptor.CipherAlgorithm to be used
