Hi Stef,

The DESPlugin implements the DES cryptography algorithm, which has  
basically two parts.  Key preparation, which DES calls "cooking the  
key", and transformation, where it takes the cooked key and the input  
block and encrypts it or decrypts it.  I have always wished that  
there were an in-image implementation so that the plugin isn't  
required when doing DES, but it hasn't happened yet.  Something to  
work on, perhaps.  Note that I didn't write it, I am only a user.

Robert
