node-crypt3

crypt(3) for Node.js

Installation

Install using npm install crypt3 and use:

Promise version using Q library

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

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

Async version

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

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

Sync version

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

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

Example password encoding

Use crypt(key[, salt]):

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, glibc2 only
console.log( crypt('6Xz7sS6fEmnWScMb6Ayf363e5cdqF4Kh', crypt.createSalt('sha512') ) );      // SHA-512, glibc2 only

Create hashes

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

Please note that this library does not work on Windows, and usually has a limited functionality on other *NIX systems other than Linux.
