+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 persistant 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.md).
+
+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`
+
