public AES128Gcm()
          throws IOException

Throws:

IOException

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

transform

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

Description copied from class: AbstractSshCipher

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 interface SshCipher

Overrides:

transform in class AbstractJCECipher

Throws:

IOException

isMAC

public boolean isMAC()

Specified by:

isMAC in interface SshCipher

Overrides:

isMAC in class AbstractSshCipher

getMacLength

public int getMacLength()

Specified by:

getMacLength in interface SshCipher

Overrides:

getMacLength in class AbstractSshCipher
