[crypt(3)][crypt3link] for Node.js

Installation
------------

Install using npm install crypt3-prebuilt and use:

``javascript
var crypt = require('crypt3-prebuilt');
`

Example password check
----------------------

`javascript
if( crypt('6Xz7sS6fEmnWScMb6Ayf363e5cdqF4Kh', '$1$SrkubyRm$DEQU3KupUxt4yfhbK1HyV/') !== '$1$SrkubyRm$DEQU3KupUxt4yfhbK1HyV/' ) {
console.error('Access denied!');
return;
}
`

Example password encoding
-------------------------

Use crypt(key[, salt]):

`javascript
console.log( crypt('6Xz7sS6fEmnWScMb6Ayf363e5cdqF4Kh') ); // Salt generated automatically using default SHA512
console.log( crypt('6Xz7sS6fEmnWScMb6Ayf363e5cdqF4Kh', crypt.createSalt('md5') ) ); // MD5 salt
console.log( crypt('6Xz7sS6fEmnWScMb6Ayf363e5cdqF4Kh', crypt.createSalt('blowfish') ) ); // Blowfish salt (only some Linux distros)
console.log( crypt('6Xz7sS6fEmnWScMb6Ayf363e5cdqF4Kh', crypt.createSalt('sha256') ) ); // SHA-256
console.log( crypt('6Xz7sS6fEmnWScMb6Ayf363e5cdqF4Kh', crypt.createSalt('sha512') ) ); // SHA-512
`

Create hashes
-------------

Use crypt.createSalt([type=sha512]) where type is one of md5, blowfish, sha256 or sha512` (default).
