argon2Sync

Provides a synchronous Argon2 implementation. Argon2 is a password-based key derivation function that is designed to be expensive computationally and memory-wise in order to make brute-force attacks unrewarding.

The nonce should be as unique as possible. It is recommended that a nonce is random and at least 16 bytes long. See NIST SP 800-132 for details.

When passing strings for message, nonce, secret or associatedData, please consider caveats when using strings as inputs to cryptographic APIs.

An exception is thrown when key derivation fails, otherwise the derived key is returned as a Buffer.

An exception is thrown when any of the input arguments specify invalid values or types.

const { argon2Sync, randomBytes } = await import('node:crypto');

const derivedKey = argon2Sync('argon2id', parameters);
console.log(derivedKey.toString('hex'));  // 'af91dad...9520f15'
