  <p>I've been doing a lot with PHP recently and want to make my first login/registration system. As such I've been doing a lot of reading online to figure out the best method(s) for doing this. I've come across a couple of guides and I'm confused on a few instances and I'd like to be sure before I start down this road.</p>
  
  <p>My question is how exactly do I use blowfish? I've read that crypt() will auto select blowfish if an appropriate salt is provided. If that is the case, What makes a salt blowfish appropriate?</p>
  
  <p>Right now, I have a script that makes a salt out of the date and time, a random number, then hash that for the salt. Is that something I can use with blowfish or not?</p>
