javax.crypto: encrypte a string with Standard DES encryption with a 2-char SALT

[ClaudiaE]

Hello,

can anyone help me? I want to encrypt a string with DES encryption in
Java. I have a 2 char salt for encryption. I have no key. Can anyone
tell me the way to do that?

Thanks,

Claudia E.

How about . . .

Key key = KeyGenerator.getInstance("DESede").generateKey();
IvParameterSpec iv = new IvParameterSpec(<your bytes>);

Cipher cipher = Cipher.getInstance("DESede/CBC/NoPadding");
cipher.init(Cipher.ENCRYPT_MODE, key, iv);
. . .
byte[] encrypted = cipher.doFinal(<your String>.toBytes());

.. . . but you'll have to figure out padding yourself. You can change
the instance of the cipher or pad using your own scheme by finding
the block size of the cipher.
