unix-crypt-td-js

What is unix-crypt-td-js?

The unix-crypt-td-js npm package is a JavaScript implementation of the traditional Unix crypt function, which is used for hashing passwords. It supports various hashing algorithms including DES, MD5, SHA-256, and SHA-512.

What are unix-crypt-td-js's main functionalities?

DES Hashing

This feature allows you to hash a password using the DES algorithm. The 'salt' parameter is used to perturb the hashing algorithm.

const unixCrypt = require('unix-crypt-td-js');
const hashedPassword = unixCrypt('password', 'salt');
console.log(hashedPassword);

MD5 Hashing

This feature allows you to hash a password using the MD5 algorithm. The salt parameter should start with '$1$' to indicate MD5 hashing.

const unixCrypt = require('unix-crypt-td-js');
const hashedPassword = unixCrypt('password', '$1$salt$');
console.log(hashedPassword);

SHA-256 Hashing

This feature allows you to hash a password using the SHA-256 algorithm. The salt parameter should start with '$5$' to indicate SHA-256 hashing.

const unixCrypt = require('unix-crypt-td-js');
const hashedPassword = unixCrypt('password', '$5$salt$');
console.log(hashedPassword);

SHA-512 Hashing

This feature allows you to hash a password using the SHA-512 algorithm. The salt parameter should start with '$6$' to indicate SHA-512 hashing.

const unixCrypt = require('unix-crypt-td-js');
const hashedPassword = unixCrypt('password', '$6$salt$');
console.log(hashedPassword);

Other packages similar to unix-crypt-td-js

bcrypt

bcrypt is a popular library for hashing passwords using the bcrypt algorithm. It is widely used for its security and ease of use. Unlike unix-crypt-td-js, bcrypt is specifically designed for password hashing and includes features like automatic salt generation and password comparison.

pbkdf2

pbkdf2 is a library that implements the PBKDF2 (Password-Based Key Derivation Function 2) algorithm. It is used for securely hashing passwords and is considered more secure than traditional Unix crypt methods. It offers more flexibility in terms of iterations and key length.

argon2

argon2 is a modern and secure password hashing library that won the Password Hashing Competition in 2015. It is designed to be memory-hard to resist GPU cracking attacks. Argon2 offers more advanced security features compared to traditional Unix crypt methods.

README

Unix crypt(3) Javascript Implementation

Straightforward implementaiton of the DES-based Unix crypt(3) hash, based largely on crypt.c in the Seventh Edition Unix distribution released by Caldera Systems under a BSD-style license.

Building the minified version

Running the Makefile requires the Google Closure Compiler installed on your path. Alternatively, you may use any JS Minifier you want.

Usage

Simple examples:

unixCryptTD('foob' /* pw */, 'ar' /* salt */) // === 'arlEKn0OzVJn.'
unixCryptTD([102, 111, 111, 98], 'ar') // === 'arlEKn0OzVJn.'
unixCryptTD([102, 111, 111, 98], [97, 114] // === 'arlEKn0OzVJn.'
unixCryptTD('foob', 'ar', true /* returnBytes */) // === [97, 114, 108, 69,
                                 // 75, 110, 48, 79, 122, 86, 74, 110, 46]

Testing

Just run npm test
