    Subject: JCE: algorithm parameters and key size

    Date: Tue, 6 May 1997 08:21:15 -0700

In the JCE, if I want to create a DES object, I call
Cipher.getInstance ("DES"). But suppose I want to create an object that
executes an encryption algorithm that requires one or more parameters.
For instance, RC2 needs to know the effective key bit value. How do I
set an object's parameters?

Along the same lines, if I want to generate a DES key, I can use
KeyGenerator.getInstance ("DES") and the generate method. But if I'm
generating an RC2 key, how do I specify its length?
