title: What is a good PHP hashing algorithm for account verification by email?
body: <p>What is the best algorithm to create a hash (as a verification id) for new users to verify their accounts?</p>
  
  <p>MD5 seems to be the answer everywhere I look, but all the sources are at least 3 or 4 years old. I just want to make sure that MD5 is still the best option today...</p>
  
  <p>I use the <code>password_hash()</code> function for passwords which I belive uses the Blowfish algorithm and adds a random salt, but is that necessary for a verification ID?</p>
