SAML Chrome Panel Extension

This is an Open Source SAML debugger for Chrome. It operates as another panel in the Chrome Developer Tools section, which monitors the traffic in the current active tab. This panel is trying to replicate what the Firefox version of SAML Tracer does as there wasn't a good enough one (or any) for Chrome at the time of writing this.

GitHub Repo: https://github.com/milton-lai/saml-chrome-panel
Feel free to branch and help make this even better!

It is designed to display all network traffic, along with the request and response data. If there is a SAML request or response, then it will grab the message, format it nicely and show it to you in another tab.

Updates:
- Set links to open in the same browser
-- There is a new feature to \"Scrub\" the links in the current page. Basically, it will update all anchor tags and set their target attribute to equal '_self'. This should address the issue of having SAML transactions opening up in new tabs and such. This is the best implementation I could think of as I'm unable to listen to all traffic on all tabs.
- Import and export the network traffic.
-- It imports and exports the traffic on the browser in a JSON format.
- Toggle showing SAML traffic.

Please note that at the moment, I've only looked at OpenAM Redirect and POST SAML transactions (as that is what I've got access to). If there are others which are working, please let me know. If there are SSO frameworks that are not working, then also please let me know and I'll try to get it working (e.g. SOAP).

Paula Martínez (ID: 0000004411e1e615) Voted 2 ★ - Updated 11/07/2023 Para mi gusto, la peor de las tres opciones de extensión que hay para Chrome, te obliga a estar inspeccionando y si no estás inspeccionando de antes de que se lancen las llamadas a SAML, no te aparecen, cuando las demás extensiones te las muestra la abras cuando la abras

jayesh kothari (ID: 0000007a56815cd3) Voted 2 ★ - Updated 08/10/2023 Recently, the panel doesn't show up on the dev tools. I have tried on Mac, windows(PC, AVD, Citrix) and randomly it would just show up after multiple attempts of opening and closing the browser completely. This was the extension of choice always but no longer.

David Tod (ID: 0000000c5940e61f) Voted 5 ★ - Updated 02/16/2023 Excellent. Does the job and solves the problem. Would love to see it support other base64-encoded data like OAuth (id_token) and LTI (lti_message_hint).

Jack Cuneo (ID: 0000005f4d45b70f) Voted 5 ★ - Updated 03/16/2022 Great extension. Just add to Chrome, open Dev Tools, choose the spiffy new "SAML" tab that appears there, and run through your flow. Looks good, works well, and building it into Dev Tools makes it unobtrusive. Thank you!
