Modifier and Type	Method and Description
int	getMacLength()
void	init(int mode, byte[] iv, byte[] keydata) Initialize the cipher with up to 40 bytes of iv and key data.
boolean	isMAC()
void	transform(byte[] buf, int start, byte[] output, int off, int len) Transform the byte array according to the cipher mode; it is legal for the source and destination arrays to reference the same physical array so care should be taken in the transformation process to safeguard this rule.

Method Detail

init

public void init(int mode,
                 byte[] iv,
                 byte[] keydata)
          throws java.io.IOException

Description copied from class: SshCipher

Initialize the cipher with up to 40 bytes of iv and key data. Each implementation should take as much data from the initialization as it needs ignoring any data that it does not require.

Overrides:

init in class AbstractJCECipher

Parameters:

mode - the mode to operate

iv - the initiaization vector

keydata - the key data

Throws:

java.io.IOException

transform

public void transform(byte[] buf,
                      int start,
                      byte[] output,
                      int off,
                      int len)
               throws java.io.IOException

Description copied from class: SshCipher

Transform the byte array according to the cipher mode; it is legal for the source and destination arrays to reference the same physical array so care should be taken in the transformation process to safeguard this rule.

Overrides:

transform in class AbstractJCECipher

Throws:

java.io.IOException

isMAC

public boolean isMAC()

Overrides:

isMAC in class SshCipher

getMacLength

public int getMacLength()

Overrides:

getMacLength in class SshCipher
