+
+This library provides the functionality of PBKDF2 with the ability to use any supported hashing algorithm returned from `crypto.getHashes()`
+
+
+## Usage
+
+```js
+var pbkdf2 = require('pbkdf2')
+var derivedKey = pbkdf2.pbkdf2Sync('password', 'salt', 1, 32, 'sha512')
+
+...
+```
+
+For more information on the API,  please see the relevant [Node documentation](https://nodejs.org/api/crypto.html#crypto_crypto_pbkdf2_password_salt_iterations_keylen_digest_callback).
+
+For high performance,  use the `async` variant (`pbkdf2.pbkdf2`),  not `pbkdf2.pbkdf2Sync`,  this variant has the oppurtunity to use `window.crypto.subtle` when browserified.
+
+
+## Credits
+
+This module is a derivative of [cryptocoinjs/pbkdf2-sha256](https://github.com/cryptocoinjs/pbkdf2-sha256/), so thanks to [JP Richardson](https://github.com/jprichardson/) for laying the ground work.
+
+Thank you to [FangDun Cai](https://github.com/fundon) for donating the package name on npm, if you're looking for his previous module it is located at [fundon/pbkdf2](https://github.com/fundon/pbkdf2).
