I’ve put in github my django program to monitor certificates – django-certiffy

It can be deployed quite quickly and easily for testing:
I find it useful with nearly 300 certificates on our campus being tracked and replaced, its a daily task now. This helps generate keys and Certifcate Signing Requests, keep track of the owners, give people enough warning, and help see what is coming up. Oh, and it grades them using Qualys SSL Labs.
