init(boolean forEncryption,
CipherParameters params) |
Initialise the cipher.

int len,
byte[] out,
int outOff) |
process a block of bytes from in putting the result into out.
|
void |
reset() |
reset the cipher.
|
byte |
returnByte(byte in) |
encrypt/decrypt a single byte returning the result.

void init(boolean forEncryption, CipherParameters params) throws java.lang.IllegalArgumentException
forEncryption
- if true the cipher is initialised for
encryption, if false for decryption.params
- the key and other data required by the cipher.java.lang.IllegalArgumentException
- if the params argument is
inappropriate.java.lang.String getAlgorithmName()
