+synopsis:            A pure haskell library implements several hash algorithms.
+description:         hashing is a pure haskell hash library, supported hash algorithm: SHA1/SHA224/SHA256/SHA384/SHA512
+                     MD5 and Whirlpool. It provides a simple interface ``hash`` and ``hashLazy`` to compute a hash value
+                     Based on the type signature.
+                     Performance wise it only has 1/5 - 1/15 of native C implementations, or ``cryptonite``.
+                     Compare to other pure hash libraries such as PureMD5/SHA, it provides a simpler interface, 
+                     implements more algorithms, and has less dependencies.
