If you want to transform your problems into my tasks, or simply have questions, please contact me.
A few words about me: I support my clients with words and deeds. Together with Juan Carlos Cruellas I chair the technical committee for advanced digital signature services at the “Organization for the Advancement of Structured Information Standards” (OASIS DSS-X TC).
Latest publication: Stefan Drees et al., “Digital Signature Service Core Protocols, Elements, and Bindings” Version 1.0, OASIS Standard, 11 April 2007: (HTML, PDF).
