Encode Authorization Header Plugin for Burp Suite
This Burp Suite plugin modifies a proxied request to Base-64 encode the Authorization header. It is written completely in Java and takes advantage of the Burp 1.5.x Extender API.
The purpose of this extension is to allow you to use a tool such as SQLMap to attack the username and/or password fields in the Authorization header, which is Base-64 encoded (SQLMap will not Base-64 encode its payloads). By proxying the request through Burp Suite, and using this plugin, we can achieve the same result.
I'd be interested in any feedback, please contact me.
