          Initialize the cipher with up to 40 bytes of iv and key data.
 void transform(byte[] src, int start, byte[] dest, int offset, 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.

Constructor Detail

SshDes3

public SshDes3()
Method Detail

getBlockSize

public int getBlockSize()
Description copied from class: SshCipher
Get the cipher block size.

Specified by:
getBlockSize in class SshCipher
Returns:
the block size in bytes.

getAlgorithm

public java.lang.String getAlgorithm()
Overrides:
getAlgorithm in class SshCipher

init

public void init(int mode,
                 byte[] iv,
                 byte[] keydata)
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.

Specified by:
init in class SshCipher
Parameters:
mode - the mode to operate
iv - the initiaization vector
keydata - the key data

transform

public void transform(byte[] src,
                      int start,
                      byte[] dest,
                      int offset,
                      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.

Specified by:
transform in class SshCipher
Parameters:
offset -
len -
Returns:
the transformed data
Throws:
java.io.IOException
