I have access to the following:

  1. PHP (Latest)
  2. MySQL

And I need to develop a way of checking certificates that we create. The certificates need to hold: "SiteName", "ID", "DevelopedTeam". And it needs to be verified from any server through mySQL.

The problem i am having is making a custom vertificate with all of these variables ... but cannot be read with out decoding it... any help on where to start?
