+Node style aes for use in the browser.  Implements:
+
+ - createCipher
+ - createCipheriv
+ - createDecipher
+ - createDecipheriv
+ - getCiphers
+
+In node.js, the `crypto` implementation is used, in browsers it falls back to a pure JavaScript implementation.
+
 Much of this library has been taken from the aes implementation in [triplesec](https://github.com/keybase/triplesec),  a partial derivation of [crypto-js](https://code.google.com/p/crypto-js/).
 
 `EVP_BytesToKey` is a straight up port of the same function from OpenSSL as there is literally no documenation on it beyond it using 'undocumented extensions' for longer keys.
