Error in SAML response - SignatureDescription could not be created for the signature algorithm supplied #80

Closed vishnureddydotnet closed 1 year ago

I am facing issue in samlResponse.IsValid() method. The code is breaking at this point return ValidateSignatureReference(signedXml) && signedXml.CheckSignature(_certificate, true) && !IsExpired();

The method signedXml.CheckSignature(_certificate, true) is returning an exception : "SignatureDescription could not be created for the signature algorithm supplied."

The error is happening in IsValid() method in file Saml.cs (Line no- 74)

In The Saml response which we are getting in XmlDocument object there is a line: ds:SignedInfo>

But the link http://www.w3.org/2001/10/xml-exc-c14n# opens as a web page. Is that correct behavior?

What could be the possible cause of this and how to resolve this? Please help. Thanks in advance.

Which .NET version? .NET version of our application is 4.6.1

Upgrading to at least 4.6.2 should resolve this
