how to retrieve SSL certificate informations?

[Marc Worrell]

As there is some interest in such a library I will start with splitting off code from the Zotonic code base into a separate application.

I can do that tomorrow.

Then we can start adding extra functionality afterwards.


Cheers, Marc

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?
