Hi Marc,

This is a very timely topic in a current project I’m working on at the moment.  We need to determine the expiration date of a certificate as well as generate a self-signed one, which I see this module does as well.  Could you please isolate it in a separate library so we can include it in our list of OSS components?

Hi Benoît,

If the below is what you are looking for, then I can also isolate it in a separate library app for inclusion in your projects.

How can I get informations about an SSL certificate ? Specifically I am looking for a way to retrieve the issuer, subject, and the  serial number of the certificate.

The record I get from decoding using public_key functions is hard to parse so any help is welcome. Maybe there is already an api/app somewhere for it?
