I’ve been testing and trying to implement an application that uses an IDP through SAML. I’ve connected my Auth0 application to a test implementation of it, where it’s also been registered.
The problem is that the IDP apparently uses rsa-sha384 encryption which Auth0 currently does not support.
Unfortunately, as you have observed, the rsa-sha384 signature algorithm is not currently supported. At this time, I do not see any plans to support this algorithm in the future. The only supported signing algorithms can be found here.
With that said, if you believe that this is a feature that should be included, would you mind putting in a feature request at Auth0 Feedback to get this feature prioritized?
Please let me know if you have any other questions.
