I am trying two things. i) Sign an xml document with verisign's tsik and verify it with open saml 2.x library (open saml internally uses xmltooling library. ii) Sign an xml doc with open saml library and verify it with tsik.
I am able to do #1 successfully. But in case of #2, signature validation is FAILING.
In both the cases I use "rsa-sha1" as the signing algorithm and "c14n" as the canonicalization algorithm.
To debug more on the issue, I tried online to get the source code for tsik, but I am not able to find any reference for tsik library at all..
