Method Details

init

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

Description copied from class: AbstractSshCipher

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 interface SshCipher

Overrides:

init in class AbstractJCECipher

Parameters:

mode - the mode to operate

iv - the initiaization vector

keydata - the key data

Throws:

IOException

getBlockSize

public int getBlockSize()

Description copied from class: AbstractSshCipher

Get the cipher block size.

Specified by:

getBlockSize in interface SshCipher

Overrides:

getBlockSize in class AbstractJCECipher

Returns:

the block size in bytes.
