I’ve been reading a bunch of stuff about security and I’m just now starting to try and play around with the code. I want to use MD5 encryption with a salt. I ran across this nifty PHP script with random salt:
substr(str_shuffle(str_repeat('ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789',5)),0,10);
It randomly generates some characters as salt, but then I was thinking: How would I go about checking logins? Do I remove the salt, or should I store it in the database?
Store it in database. Otherwise you can’t compare password provided by user with hashed one.
Some even regenerate hash (with new salt) upon each successful login of given user, although commenters below argue this is not the best idea (see comments)
