title: What are Salt Rounds and how are Salts stored in Bcrypt?
body: <p>I'm trying to configure Bcrypt for a node app that I'm making and have several questions about salts that I hope someone here can help kindly answer.</p>
  
  <ul>
  <li><p>What is a salt 'round'? For example, in the github docs (<a href="https://github.com/kelektiv/node.bcrypt.js/" rel="noreferrer">https://github.com/kelektiv/node.bcrypt.js/</a>) it uses a salt round of 10. What does that mean exactly?</p></li>
  <li><p>Is the salt generated by Bcrypt always the same? For example, if I am saving user's hashed passwords to a DB, is the salt that it used to hash the password the same for every password?</p></li>
  <li><p>How is the salt stored? Is it secure from potential attacks?</p></li>
  </ul>
