I am also getting the message about no valid SAP Crypto. I have followed the instructions from a number of guides I have found (cannot paste links since paste does not work on these forums). One slight difference is that I cannot use the SAP Crypto libraries since I am based in America. I created a self-signed cert using OpenSSL instead, but still no luck.
Is there any guidance on how to do this? I've seen conflicting guides and none seem to describe how to use OpenSSL instead of SAP Crypto.
