AESPasswordCiphertext

public AESPasswordCiphertext()

Method Detail

newCipherInstance

protected org.bouncycastle.crypto.paddings.PaddedBufferedBlockCipher newCipherInstance()

The cipher engine. It is very important to wrap the engine with CBC or similar, otherwise large patches of the same data will translate to large patches of the same ciphertext. see: http://en.wikipedia.org/wiki/Block_cipher_modes_of_operation

Specified by:

newCipherInstance in class AbstractPasswordCiphertext

Returns:

a new instance of the cipher engine to use.
