Abstract

An improved certificate issuing system may comprise a novel arrangement for expressing certificate issuing policy. The policy may be expressed in a human-readable policy expression language and stored for example in a file that is consumed by a certificate issuing system at runtime. The policy may thus be easily changed by altering the digital file. Certain techniques are also provided for extending the capabilities of the certificate issuing system so it may apply and enforce new policies.
