title: Hashing in phpMyAdmin
body: <p>I have a mySQL database and I am using phpMyAdmin to access it. The database has table employees with fields like name, address, email and password. </p>
  
  <p>Initially the password field was just <code>VARCHAR (20)</code>. But now I want to hash my password with SHA-256 hashing technique. </p>
  
  <p>I do not have much experience with databases so I want to know is -</p>
  
  <ol>
  <li><p>can I hash all my current employees passwords without affecting the other fields or the entire table?</p></li>
  <li><p>In future when I am entering data in the database (from a web application), where do I write the hashing function to hash the password? i.e. does the hashing occurs at the front end and then the hashed password is stored in the DB or the password goes to the DB where it is hashed and then stored.</p></li>
  </ol>
  
  <p>Solution and Suggestions are appreciated. </p>
