Certificate Authority

UW CA Home > CRL
Note: Although still usable, this Certificate Authority application now has legacy status. The new UW Certificate Services application provides consolidated certificate request and management functions for both the UW Services CA and the InCommon CA. See the UW Certificate Services documentation for a comparison of CA features.

Working with the CRL

Using the Certificate Revocation List (CRL)

The CRL identifies those certificates that the UW CA has determined are no longer valid and has revoked. Use of a CRL is not necessary, but does enhance the security of your client or service.

Specific use depends on your application. PEM format is convenient because you can copy the text from your browser and paste it into an application or file. The CRL in DER format contains unprintable characters and does not lend itself to the copy and paste method. Many applications can, however, work more easily with the DER format.

In addition, certificates issued by the CA contain CRL distribution point information. Someday soon software products will automatically make use of that information - thereby obviating the manual distribution method.
