+=== Using your public SSH key as a signing key ===
+You can naturally configure git to automatically sign your commits using your public SSH key like so:<syntaxhighlight lang="nix">
+{
+  programs.git = {
+    enable = true;
+    signing = {
+      key = "ssh-ed25519 AAAAAAAAAAAA...AA username@hostname";
+      signByDefault = true;
+    };
+    extraConfig = {
+      gpg = {
+        format = "ssh";
+      };
+    };
+  };
+}
+</syntaxhighlight>However, note that this will also require Home Manager to manage your SSH configuration:<syntaxhighlight lang="nix">
+{
+  programs.ssh = {
+    enable = true;
+    addKeysToAgent = "yes";
    };
 }
