Are you using the xml file from the example or some other file?
If it is a custom file, then it would be helpful if you can share it.

Thanks

Hello,

I have am xml document and x509 public key that I'm trying to verify
the signature on. I've compiled the unmodified verify3 example program
that is in the xmlsec tarball and it is the program I'm using to try
to verify the signature.

Here is the output:

func=xmlSecOpenSSLEvpDigestVerify:file=digests.c:line=229:obj=sha1:subj=unknown:error=12:invalid
 data:data and digest do not match
Signature is OK

I admit I'm very new to the security mechanism and I don't have a
solid understanding of the specifications. However, it seems to me if
there is invalid data (the data and digest do not match) then the
signature verification should be considered a failure.

How should the results of verify3 be interpreted? Was the signature
verification really a success with that error?
