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.

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.

Much of this library has been taken from the AES implementation in triplesec (apparently licensed MIT), which is a partial derivation of crypto-js, which is licensed BSD-3 clause, the relevant LICENSE text for both MIT and BSD-3 can be found in LICENSE.

Parts of ghash.js are a partial derivation of work by Juho Vähä-Herttua in SJCL, which is LICENSED BSD-2 || GPL-2, with the LICENSE text included inline in ghash.js.
