Using Letsencrypt on an ASA5500 firewall


I have written a python script that requires a box, a web server running on it, python 3.x, paramiko-expect

It can be found at

or directly downloaded from:

You can port it to Windows as well and run it on a Windows box, but it was initially written for a linux machine.

This was due to github only supporting 5500x or ASAv’s due to the API limitations.


I’m not sure what you’re asking here. Are you trying to secure the connections to that script using a Let’s Encrypt certificate? Does that script attempt to request Let’s Encrypt certificates?
