Dear Dennis,
Seems like you are missing the SAPCRYPTOLIB.
You can check this SAP Note: 1375378 - Select the right version of an SAP security toolkit
Also, you can look at the info Note on page 65 of the SAP NetWeaver SSO 2.0 Implementation Guide: http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/70412b93-c972-3010-6a94-da49f9ba5192?QuickLink=index&overridelayout=true&58858231824548
I hope this will help you.
Kind regards,
Donka Dimitrova
