Walter,

I copied some stuff of my crypto class and made an rc4 class. Rc4 algorithm can be found on google, I found it there. Can be made a lot faster in C

You should be able to encrypt/decrypt long strings in blocks with this using ContinueWithPreviousKey. I have not tested this !
I have only used it in last step of the decyption of pfd docs.

I do not know whether I am/would be violating any patented material. Some claim it's patented whilst others state it is not.
Anyway, I am sending it to your mail, just in case

Enjoy
