title: What data type to use for hashed password field and what length?
body: <p>I'm not sure how password hashing works (will be implementing it later), but need to create database schema now.</p>
  
  <p>I'm thinking of limiting passwords to 4-20 characters, but as I understand after encrypting hash string will be of different length.</p>
  
  <p>So, how to store these passwords in the database?</p>
