Does anyone know of a reference implementation for Stefan Brands's digital certificate scheme? Alternatively, does anyone have an email address for Brands so I can ask him myself? (I haven't gotten anything back from ZKS's "contact us" address. But I don't know if Brands is still at ZKS.)
He started a new company called Credentica.
