Http Digest Authentication, Handle different browser char-sets...
- by user160561
Hi all,
I tried to use the Http Authentication Digest Scheme with my php (apache module) based website. In general it works fine, but when it comes to verification of the username / hash against my user database i run into a problem.
Of course i do not want to store the user´s password in my database, so i tend to store the A1 hashvalue (which is md5($username . ':' . $realm . ':' . $password)) in my db.
This is just how the browser does it too to create the hashes to send back.
The Problem:
I am not able to detect if the browser does this in ISO-8859-1 fallback (like firefox, IE) or UTF-8 (Opera) or whatever. I have chosen to do the calculation in UTF-8 and store this md5 hash. Which leads to non-authentication in Firefox and IE browsers.
How do you solve this problem?
Just do not use this auth-scheme? Or Store a md5 Hash for each charset?
Force users to Opera?
(Terms of A1 refer to the http://php.net/manual/en/features.http-auth.php example.)
(for digest access authentication read the according wikipedia entry)
