Define the hash and verifyHash functions directly in node interpreter:

Singularity> pwd
/sw/apps/dpdash/

Singularity> node
Welcome to Node.js v16.4.0.
Type ".help" for more information.
> const { randomBytes, pbkdf2Sync } = require('crypto')
undefined
> const hash = (text) => {
  const salt = randomBytes(16).toString('hex');
  const hash = pbkdf2Sync(text, salt, 2048, 32, 'sha512').toString('hex');
  return [salt, hash].join('$');
}

const verifyHash = (text, original) => {
  const originalHash = original.split('$')[1];
  const salt = original.split('$')[0];
  const hash = pbkdf2Sync(text, salt, 2048, 32, 'sha512').toString('hex');
  return hash === originalHash;
}
undefined
> hash('dpdash')

In the last line, generate hash for your arbitrary password and update the corresponding collection in dpdmongo.users.
