+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.
