Sorry if the answer here is obvious, but was hoping someone could help me u=
nderstand the difference between these two messages from xmlsec while verif=
ying some SAML docs.


1.       This first message I get when intentionally trying to verify a (kn=
own to be valid) SAML Metadata file with the wrong cert

func=3DxmlSecOpenSSLEvpSignatureVerify:file=3D..\src\openssl\signatures.c:l=
ine=3D346:obj=3Drsa-sha256:subj=3DEVP_VerifyFinal:error=3D18:data do not ma=
tch:signature do not match



2.       However when trying to verify a SAML assertion with the (thought t=
o be) correct cert, or an incorrect cert, I get the following in both cases:


func=3DxmlSecOpenSSLEvpDigestVerify:file=3D..\src\openssl\digests.c:line=3D=
229:obj=3Dsha256:subj=3Dunknown:error=3D12:invalid data:data and digest do =
not match

I'm trying to debug an issue with an SAML assertion failing signature valid=
ation, and I would have expected that trying to verify the assertion with t=
he wrong cert would produce the same error from #1...but regardless of the =
cert, I get the message in #2

Thanks for any help,
Kevin..
