Interface Decryptor

All Known Implementing Classes:

AESDecryptor

@InterfaceAudience.Public
@InterfaceStability.Unstable
public interface Decryptor

Decryptors apply a cipher to an InputStream to recover plaintext.

Method Summary

InputStream	createDecryptionStream(InputStream in) Create a stream for decryption
int	getBlockSize() Get the cipher's internal block size
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
