The Readme file for this project assumes knowledge

[David263]

The Readme file for this project assumes that the reader knows exactly how OpenID works. This contradicts the statement that it assumes minimal knowledge of OpenID Connect.

The first function described requires a certificate. Right away I'm puzzled. Why would OpenID Connect require a security certificate?

I probably should state my use case: I am creating a website and want to add PHP code to obtain the user's username and password and authenticate it using OpenID Connect based on credential data stored in a reliable web source or my own user registration file. Seems like a simple enough goal, but I'm having trouble getting started. Is OpenID Connect appropriate for this goal, or should I write my own HMAC/encryption solution?
