I use Mujina to serve as IDP, but the SP require encryption for the SAML assertion. The metadata of the SP contain "encryption": ```xml <md:KeyDescriptor use="encryption"><ds:KeyInfo xmlns:ds="http://www.w3.org/2000/09/xmldsig#"><ds:X509Data><ds:X509Certif icate>MIIEAzCCAuugAwIBAgIUI4qKN939RQDNUu/xfdzQXYmMfuowDQYJKoZIhvcNAQELBQAwgZAxCzAJ BgNVBAYTAlRXMQ8wDQYDVQQIDAZUYWl3YW4xETAPBgNVBAcMCFRhbyBZdWFuMSQwIgYDVQQKDBtO ... ``` Will it possibly work with Mujina IDP? And how should I do to make the it work.
