NodeJS implementation for Python's pbkdf2_sha256.verify

Question

I have to translate this Python code to NodeJS:

from passlib.hash import pbkdf2_sha256
pbkdf2_sha256.verify('12345678', '$pbkdf2-sha256$2000$8R7jHOOcs7YWImRM6V1LqQ$CIdNv8YlLlCZfeFJihZs7eQxBsauvVfV05v07Ca2Yzg')
>> True

The code above is the entire code, i.e. there is no othe parameters/settings (just run pip install passlib before you run it to install the passlib package).

I am looking for the correct implementation of validatePassword function in Node that will pass this positive implementation test:

validatePassword('12345678', '$pbkdf2-sha256$2000$8R7jHOOcs7YWImRM6V1LqQ$CIdNv8YlLlCZfeFJihZs7eQxBsauvVfV05v07Ca2Yzg')
>> true

Here is the documentation of the passlib.hash.pbkdf2_sha256 with its default parameters' values.

I tried to follow the answers from here with the data from the Python code above, but that solutions didn't pass the test.

I would appreciate some help with this implementation (preferably using built-in NodeJS crypto package).

Thank you in advance.

Answer 1

This would work:

const crypto = require('crypto')
function validatePassword(secret, format) {
    let parts = format.split('$')
    return parts[4] == crypto.pbkdf2Sync(secret, Buffer.from(parts[3].replace(/\./g, '+') + '='.repeat(parts[3].length % 3), 'base64'),
        +parts[2], 32, parts[1].split('-')[1]).toString('base64').replace(/=/g, '').replace(/\+/g, '.')
}
