summary: Log certificate status and fingerprint of remote servers

...

Introduction

============

This module produces info level log messages with the certificate status

and fingerprint every time an s2s connection is established. It can also

optionally store this in persistent storage.

**info** jabber.org has a trusted valid certificate with SHA1:

11:C2:3D:87:3F:95:F8:13:F8:CA:81:33:71:36:A7:00:E0:01:95:ED

Fingerprints could then be added to

[mod\_s2s\_auth\_fingerprint](mod_s2s_auth_fingerprint.html).

Configuration

=============

Add the module to the `modules_enabled` list.

    modules_enabled = {

        ...

        "s2s_log_certs";

    }

If you want to keep track of how many times, and when a certificate is

seen add

`s2s_log_certs_persist = true`
