Method Summary |
java.lang.String |
getAlgorithm()
|
int |
getBlockSize()
Get the cipher block size. |
void |
init(int mode,
byte[] iv,
byte[] keydata)
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. |

public SshDes3()
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 operateiv
- the initiaization vectorkeydata
- the key data
transform
public void transform(byte[] src,
int start,
byte[] dest,
int offset,
int len)
throws java.io.IOException
