# Uploading public keys

Pijul and the Nest use two kinds of keypairs (public and secret): keys
for signing patches, and keys for SSH access. In order for the Nest to
display your profile alongside your changes, you need to
[associate](../keys.md#proving-keys) your key to your Nest account.

## SSH public keys

The Nest's profile settings page contains a field to add SSH public
keys. At the moment, supported formats are Ed25519 and RSA. Pijul can
handle password-protected keys, and can talk to SSH agents.
