=== 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; | |||
}; | |||
settings = { | |||
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"; | |||
}; | |||
}</syntaxhighlight> | |||

This brings many unoptimized tools to their limits, leading to long waiting times on certain operations. Here we’ll collect useful info on how to manage that. | ||
