LibTomCrypt is the on mentioned in the WinAVR documentation:

http://libtom.org/?page=features&newsitems=5&whatfile=crypt

"LibTomCrypt is a fairly comprehensive, modular and portable cryptographic  
toolkit that provides developers with a vast array of well known published  
block ciphers, one-way hash functions, chaining modes, pseudo-random  
number generators, public key cryptography and a plethora of other  
routines.

LibTomCrypt has been designed from the ground up to be very simple to use.  
It has a modular and standard API that allows new ciphers, hashes and  
PRNGs to be added or removed without change to the overall end  
application. It features easy to use functions and a complete user manual  
which has many source snippet examples.

LibTomCrypt is free for all purposes under the public domain. This  
includes commercial use, redistribution and even branching."

Tom has other libraries as well that are worth a look.
