[![npm badge][npm-badge-png]][package-url]

The goal of this module is to reimplement node's crypto module, in pure javascript so that it can run in the browser.

Here is the subset that is currently implemented:

* createHash (sha1, sha224, sha256, sha384, sha512, md5, rmd160)
* createHmac (sha1, sha224, sha256, sha384, sha512, md5, rmd160)
* pbkdf2
* pbkdf2Sync
* randomBytes
* pseudoRandomBytes
* createCipher (aes)
* createDecipher (aes)
* createDiffieHellman
* createSign (rsa, ecdsa)
* createVerify (rsa, ecdsa)
* createECDH (secp256k1)
* publicEncrypt/privateDecrypt (rsa)
* privateEncrypt/publicDecrypt (rsa)

## todo

these features from node's `crypto` are still unimplemented.

* createCredentials

## contributions

If you are interested in writing a feature, please implement as a new module,
which will be incorporated into crypto-browserify as a dependency.

All deps must be compatible with node's crypto
(generate example inputs and outputs with node, and save base64 strings inside JSON, so that tests can run in the browser)
see [sha.js](https://github.com/dominictarr/sha.js)

Crypto is _extra serious_ so please do not hesitate to review the code, and post comments if you do.
