Hello, after some further debugging, making use of a debug build of the library and GDB I've found that my failure is occurring when data unseal calls authsess_xsap_verify(xsap, &digest). which supposedly checks whether or not the session is authorised, but Im not actually sure what that means in this context, Im using the correct keys, so Im not sure what to do about not being in an "authorised session" Thanks, Sam Jenkins
