crypt-unix

A pure-JavaScript library to provide UNIX/Linux crypt(1). It uses Node's crypto for the cryptography. This tool allows you to generate and verify passwords as used in UNIX's/Linux's /etc/shadow file, or other tools that generate the same format.

| ID | Scheme | Supported | | ----------------- | ------- | --------- | | | DES | :x: | | _ | BSDi | :x: | | 1 | MD5 | ✅ | | 2, 2a, 2b, 2x, 2y | bcrypt | :x: | | 3 | NTHASH | :x: | | 5 | SHA-256 | ✅ | | 6 | SHA-512 | ✅ | | 7 | scrypt | :x: |

The unsupported formats will be added in future releases - v1.0.0 should have all of these formats available.

Export and Example

This file just has the default export: crypt(string password, string salt): boolean.

import crypt from 'crypt-unix';

const hashedPassword = "$6$saltstring$svn8UoSVapNtMuq1ukKS4tPQd8iKwSMHWjl/O817G3uBnIFNjnQJuesI68u4OTLiBFdcbYEdFCoEOfaS35inz1";

function verifyPassword(string enteredPassword): boolean {
  return crypt(enteredPassword, hashedPassword) === hashedPassword;
}
