+`jshashes` is lightweight library implementing the most extended [cryptographic hash function](http://en.wikipedia.org/wiki/Cryptographic_hash_function) algorithms in pure JavaScript (ES5 compliant).
 
-`jshashes` is a pure JavaScript implementation of the most extended [cryptographic hash function](http://en.wikipedia.org/wiki/Cryptographic_hash_function) algorithms.
-Its goal is to provide an dependency-free, fast and reliable solution for hash algorithms for both client-side and server-side JavaScript environments.
-The code is fully compatible with the ECMAScript3 language specification and was tested and used in production in all major browsers and [node.js](http://nodejs.org)/[io.js](http://iojs.org)
