Scrypt

A pure JS implementation of Scrypt. Provides methods for hashing passwords and verifying hashes with scrypt. By default, the configuration is set to the recommended values.

The output hash is a combination of the scrypt hash and the 32-bytes salt, in the format of <salt>:<hash>.

Since it's pure JS, it is anywhere from 2~3 times slower than implementations based on native code.

Constructor

function constructor(options?: { N?: number; r?: number; p?: number; dkLen?: number }): this;

Parameters

• options
  • N (default: 16384)
  • r (default: 16)
  • p (default: 1)
  • dkLen (default: 64)

Methods

• hash()
• verify()

Example

import { Scrypt } from "lucia";

const scrypt = new Scrypt();
const hash = await scrypt.hash(password);
const validPassword = await scrypt.verify(hash, password);
