How to use the pbkdf2Sync function from crypto

Find comprehensive JavaScript crypto.pbkdf2Sync code examples handpicked from public code repositorys.

crypto.pbkdf2Sync is a synchronous version of the pbkdf2 function in Node.js's built-in crypto module that derives a cryptographic key from a password using a key derivation function.

How does crypto.pbkdf2Sync work?

crypto.pbkdf2Sync is a synchronous Node.js method used to derive a key of a specified length from the given password, salt, and iteration count using the Password-Based Key Derivation Function 2 (PBKDF2) algorithm, without any callbacks or Promises.

const crypto = require("crypto");

const password = "mysecretpassword";
const salt = "mysalt";
const iterations = 10000;
const keyLength = 64;
const digest = "sha512";

const hash = crypto.pbkdf2Sync(password, salt, iterations, keyLength, digest);

console.log(hash.toString("hex"));

In this example, we use crypto.pbkdf2Sync to generate a hash for the password 'mysecretpassword' with the salt 'mysalt', using 10000 iterations, a key length of 64, and the SHA-512 algorithm. The resulting hash is printed to the console as a hexadecimal string.
