I received a nifty patch from Ken Gallo to allow ssl-cert-check to report when certificates stored in a PKCS#12 database will expire. This is super useful, especially if you are managing iPlanet/SunONE/Netscape products. If you haven’t used ssl-cert-check before, it’s a bourne shell script that can be used to alert you prior to a certificate expiring. The script is available on prefetch.net, and is documented in the article proactively handling SSL certificate expiration. Thanks Ken for the awesome patch!
