RSA Version/Condition: 4.1
ComponantSpace SAML v2.0 Single Sign-On (SSO) Component for .NET
Issue
Error message in system.out log
Unable to verify the signature value: SAMLSignedObject.verify() detected an invalid signature profile, com.rsa.fim.exception.CryptoUtilException: Unable to verify the signature value: SAMLSignedObject.verify() detected an invalid signature profile
Error message in debug.log
util.crypto.dsig.verify.error, com.rsa.fim.saml.InvalidCryptoException: SAMLSignedObject.verify() detected an invalid signature profile.
Cause
The SAML 2.x specification lists only three acceptable transforms. If a transform other than the listed ones is used this error is generated.
5.4.4 Transforms
Signatures in SAML messages SHOULD NOT contain transforms other than the enveloped signature transform (with the identifier http://www.w3.org/2000/09/xmldsig#enveloped-signature) or the exclusive canonicalization transforms (with the identifier http://www.w3.org/2001/10/xml-exc-c14n# or http://www.w3.org/2001/10/xml-exc-c14n#WithComments).
Verifiers of signatures MAY reject signatures that contain other transform algorithms as invalid.
