Interface Encryptor

All Known Implementing Classes:

AESEncryptor, CommonsCryptoAESEncryptor

@InterfaceAudience.Public
public interface Encryptor

Encryptors apply a cipher to an OutputStream to produce ciphertext.

Method Summary

Modifier and Type	Method and Description
OutputStream	createEncryptionStream(OutputStream out) Create a stream for encryption
int	getBlockSize() Get the cipher's internal block size
byte[]	getIv() Get the initialization vector
int	getIvLength() Get the expected length for the initialization vector
void	reset() Reset state, reinitialize with the key and iv
void	setIv(byte[] iv) Set the initialization vector
void	setKey(Key key) Set the secret key
