title: Node bcrypt restrict hash length
body: <p>Is it possible to restrict length of final hash while using <a href="https://www.npmjs.com/package/bcryptjs" rel="nofollow noreferrer">bcrypt js</a> </p>
  
  <p>I can find options to specify salt length, but even playing with it keeps final hash around 60 chars</p>
  
  <p>Need to hash password (capped at 20 chars) but hash is generated of 60 chars </p>
