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@@ -49,7 +49,7 @@   default-language:    Haskell2010   ghc-options: -Wall -O2   include-dirs: cbits-  includes:+  install-includes:     threefish.h   c-sources:     cbits/threefish256.c,
