Expired and not renewed certificates

[red-erik]

Hello,
is there a way to retrive issued but expired ceriticates, not already renewed ?
I did not find the proper way to do it.

Thank you in advance.

Regards,

Basically, you want to get two sets (in separate queries):

1. of all currently valid certificates
2. of expired certificates

Then, do expired.Except(valid) operation against two sets. The result will be another set which contains expired and not renewed certificates. Except in this context is your own function that contains the logic to check if entry in one set matches (or not) entry in another set.
