decrypt
public void decrypt(byte[] in,
int i,
byte[] out,
int j,
Object k,
int bs) Decrypts exactly one block of ciphertext.
- decrypt in interface IBlockCipherSpi
in - the ciphertext.out - the plaintext.k - the session key to use.bs - the block size to use.
encrypt
public void encrypt(byte[] in,
int i,
byte[] out,
int j,
Object k,
int bs) Encrypts exactly one block of plaintext.
- encrypt in interface IBlockCipherSpi
in - the plaintext.out - the ciphertext.k - the session key to use.bs - the block size to use.
makeKey
public Object makeKey(byte[] uk,
int bs)
throws InvalidKeyException Expands a user-supplied key material into a session key for a
designated block size.
- makeKey in interface IBlockCipherSpi
bs - the desired block size in bytes.
- an Object encapsulating the session key.
selfTest
public boolean selfTest()
A correctness test that consists of basic symmetric encryption /
decryption test(s) for all supported block and key sizes, as well as one
(1) variable key Known Answer Test (KAT).
- selfTest in interface IBlockCipher
- selfTest in interface IBlockCipherSpi
- selfTest in interface BaseCipher
true if the implementation passes simple
correctness tests. Returns false otherwise.
