If a key is no longer to be used, e.g. because it has fallen into the wrong hands or has been
lost, the corresponding certificate is declared invalid. The certification authority revokes the
certificate and publishes it on a certificate blacklist, so-called CRL. Certificate users should
always check against these lists to ensure that the certificate used is currently valid. This
check can be automated via a browser.
The Simple Certificate Enrollment Protocol (SCEP) supports the issue and revocation of
certificates in networks.
