Re: [keycloak-user] Keycloak as a SAML SP: Is it possible to configure Keycloak to use RSA-SHA256 as the algorithm to sign assertions.

Hi Bill, Thanks for looking into this. The usecase is: Keycloak is an SP and it is sending an AuthnRequest via HTTP Post. This AuthnRequest is always using RSA-SHA1 for signing. I have configured the Keycloak config file as follows: <keycloak-saml-adapter> <SP entityID="exampleEntityID" sslPolicy="NONE" logoutPage="/logout.jsp" nameIDPolicyFormat="urn:oasis:names:tc:SAML:2.0:nameid-format:transient" forceAuthentication="false" signatureAlgorithm="RSA_SHA256"> In-fact the SP element doesn't have the "signatureAlgorithm" documented anywhere in the SAML Client Apapter Reference Guide (it only exists for the IDP). Now this is a bit of unfamiliar territory for me, but I looked into the Keycloak Code base (master): I see that the org.keycloak.adapters.saml.config.parsers.SPXmlParser doesn't deal with ConfigXmlConstants.SIGNATURE_ALGORITHM_ATTR while the IDPXmlParser does. Again, thanks for looking into this. P.S. Sorry to all the mailing list subscribers, this "chain" might get broken despite me changing the subject. I am not sure how to fix that when using Gmail and subscribing to a digest mailing-list. Please send a direct e-mail to me if you know how to fix that.

Keycloak Saml SP? Keycloak Server interaction with an app/client? Or Keycloak Server acting as an SP in a broker scenario? They all *should* support plugging in the algorithm. Did you configure this correctly?
