+# Backend
+
+This is the backend part of the SSHecret library.
+
+The principle here is that it stores encrypted secrets that can be long to clients.
+
+It does not store much data about the clients, and purely manages access to
+encrypted values based on the SSH RSA fingerprint and an optional list of
+allowed IP addresses.
+
+While there is a model for the client, it is purely meant for aggregation and utility.
