EsPReSSO - A good morning starts with coffee!

In this posts I describe the tool, I wrote for my Bachelor thesis at the Chair for Network and Data Security, with support of Context Information Security Ltd.. EsPReSSO is a apronym for "Extension for Recognition and Processing of Single Sing on Protocols". The basic idea behind EsPReSSO is to automate standard tasks to detect and classify the Single Sign-On (SSO) Protocols OpenID, BrowserID, SAML, OAuth, OpenID-Connect, Facebook Connect and Microsoft Account. The tool is integrate with PortSwigger's HTTP Proxy, Burp Suite. Furthermore EsPReSSO integrates the WS-Attacker, to attack SAML services semi-automated or manually.
