That way you can do whatever you want with the IV. The "Ah-ha!" moment! :-) Finally I get what you are saying. Ok, sounds like a good idea.

It's just being used in counter mode. I might still implement it using the blkcipher interface as it seems strange to call it via "ctr(salsa20,..)" as it is meant to be a stream cipher after all. I always find "ecb(arc4)" kind of strange. :-) Swee Heng - To unsubscribe from this list: send the line "unsubscribe linux-crypto" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
