- Add a scheme on how to discover Husk signing keys. Siging keys mut be
  certified by the `local trust root` with a signature having a notation
  with a name equal to `signing_keys@husk-projet.org`.
- Fetch the key from the keystore.
- Expand `authenticate()` so that notation can be added to the
  signature.
- Add a test to create a signing key and fetch it from the keystore.
