Abstract. This paper discusses the technical and management experience gained in the day-by-day operation of the EuroPKI infrastructure. First the context where EuroPKI was born is explained, along with its certification philosophy. Then common certification practices are discussed, along with description of the services and applications offered by the EuroPKI partners. User-reported problems are also listed and discussed in order to identify the issues that hamper large scale adoption of public-key certificates.
