be issued by several different issuers and in varying qualities, the trustworthiness of the
issuer is extremely important. The quality of a certificate is regulated by the German Sig-
nature Act or respective EU Directives.
Certification authorities that issue so-called qualified certificates are organised in a hier-
archy with the Federal Network Agency as the higher certifying authority. The structure
and content of a certificate are stipulated by the standard used. X.509 is the most import-
ant and the most commonly use standard for digital certificates. Qualified certificates are
personal and extremely trustworthy.
Digital certificates are part of a so-called Public Key Infrastructure (PKI). PKI refers to a
system that can issue, distribute and check digital certificates.
Certificates are issued for a specific period, usually one year, i.e. they have a limited valid-
ity period.
