@ethersproject/pbkdf2

What is @ethersproject/pbkdf2?

@ethersproject/pbkdf2 is a part of the ethers.js library, which provides utilities for working with the PBKDF2 (Password-Based Key Derivation Function 2) algorithm. This package allows you to derive cryptographic keys from passwords, which is useful for securely storing passwords or generating keys for encryption.

What are @ethersproject/pbkdf2's main functionalities?

Derive Key

This feature allows you to derive a cryptographic key from a password using the PBKDF2 algorithm. The code sample demonstrates how to derive a 32-byte key using the SHA-256 hash function with 2048 iterations.

const { pbkdf2 } = require('@ethersproject/pbkdf2');
const password = 'password';
const salt = 'salt';
const iterations = 2048;
const keyLength = 32;
const derivedKey = pbkdf2(password, salt, iterations, keyLength, 'sha256');
console.log(derivedKey);

Other packages similar to @ethersproject/pbkdf2

crypto

The 'crypto' module is a built-in Node.js module that provides cryptographic functionality, including the PBKDF2 algorithm. It is a more general-purpose library compared to @ethersproject/pbkdf2 and is widely used for various cryptographic operations.

pbkdf2

The 'pbkdf2' package is a standalone implementation of the PBKDF2 algorithm. It is similar to @ethersproject/pbkdf2 in that it focuses specifically on PBKDF2, but it is not part of a larger library like ethers.js.

scrypt-js

The 'scrypt-js' package provides an implementation of the scrypt key derivation function, which is an alternative to PBKDF2. While it serves a similar purpose, scrypt is designed to be more secure against hardware brute-force attacks.
