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

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

Install using npm install crypt3 and use:

$3

``javascript
var crypt = require('crypt3/q');
`

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

$3

`javascript
var crypt = require('crypt3/async');
`

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

$3

`javascript
var crypt = require('crypt3/sync');
`

`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).
