+# Deprecated Cloud-Config Features
+
+## Retrieving SSH Authorized Keys
+
+### From a GitHub User
+
+Using the `coreos-ssh-import-github` field, we can import public SSH keys from a GitHub user to use as authorized keys to a server.
+
+```yaml
+#cloud-config
+
+users:
+  - name: elroy
+    coreos-ssh-import-github: elroy
+```
+
+### From an HTTP Endpoint
+
+We can also pull public SSH keys from any HTTP endpoint which matches [GitHub's API response format](https://developer.github.com/v3/users/keys/#list-public-keys-for-a-user).
+For example, if you have an installation of GitHub Enterprise, you can provide a complete URL with an authentication token:
+
+```yaml
+#cloud-config
+
+users:
+  - name: elroy
+    coreos-ssh-import-url: https://github-enterprise.example.com/api/v3/users/elroy/keys?access_token=<TOKEN>
+```
+
+You can also specify any URL whose response matches the JSON format for public keys:
+
+```yaml
+#cloud-config
+
+users:
+  - name: elroy
+    coreos-ssh-import-url: https://example.com/public-keys
+```

 Using a higher number of rounds will help create more secure passwords, but given enough time, password hashes can be reversed.  On most RPM based distributions there is a tool called mkpasswd available in the `expect` package, but this does not handle "rounds" nor advanced hashing algorithms.
