Skein is usable as a "normal" hash function as well as in Skein-MAC, as a cryptographically secure PRNG, as a stream cipher and as a key derivation function, all implemented according to the specifications of the Skein 1.3 paper. homepage:            http://github.com/valderman/threefish@@ -23,6 +23,7 @@     Crypto.Threefish.Authenticated,     Crypto.Threefish.Random,     Crypto.Threefish.Skein,+    Crypto.Threefish.Skein.Internal,     Crypto.Threefish.Skein.KDF,     Crypto.Threefish.Skein.StreamCipher   other-modules:
