Installation

------------

Via NPM:

    $ npm install tweetnacl-auth

or just download `nacl-auth.js` or `nacl-auth.min.js` and include it after

TweetNaCl.js:

```html

```

If using a CommonJS environment, such as Node.js, you can import it into `nacl`

nacl.auth = require('tweetnacl-auth');

```

Usage

-----

### nacl.auth(message, key)

Authenticates the given message with the secret key.

(In other words, returns HMAC-SHA-512-256 of the message under the key.)

### nacl.auth.full(message, key)

Returns HMAC-SHA-512 (without truncation) of the message under the key

### nacl.auth.authLength = 32

Length of authenticator returned by `nacl.auth`.

### nacl.auth.authFullLength = 64

Length of authenticator returned by `nacl.auth.full`.

### nacl.auth.keyLength = 32

Length of key for `nacl.auth` and `nacl.auth.full` (key length is currently not

enforced).
