 Synopsis:            Cryptol: The Language of Cryptography
 Description: Cryptol is a domain-specific language for specifying cryptographic algorithms. A Cryptol implementation of an algorithm resembles its mathematical specification more closely than an implementation in a general purpose language. For more, see <http://www.cryptol.net/>.
