Appendix H- PGP Authentication Method

In this section, we provide an example of the PGP authentication method. For this example we will start from the beginning, supposing that there is no previous mntner object created.

Create the first mntner and role object.
Install gpg or a similar tool. In this example, gpg will be used. brew install gpg
Run the next command to create public and private key gpg --gen-key. The output of this command should contain the next piece of text:
```
pub   ed25519 2024-05-03 [SC] [expires: 2027-05-03]
6A9DFE0F2C9239EF07CADA4A4BD32D1CF9C96367
```
Before creating the key-cert object gpg --export --armor 6A9DFE0F2C9239EF07CADA4A4BD32D1CF9C96367 need to be executed. This command will export the public key in plain text.

Now is time to create the key-cert object. For that you can use one of the update methods. It is recommended to use the last 8 digits from the 6A9DFE0F2C9239EF07CADA4A4BD32D1CF9C96367 for "key-cert:" attribute. For example:

key-cert:        PGPKEY-F9C96367

Once the key-cert object is created you need to update your previous mntner object adding a new "auth:" attribute pointing to the created key-cert.

Finally, now that the key-cert object is created and associated with the mntner. The last step is to perform an update authenticated with the key-cert object. In this example syncupdates is used for it.

You need to create a file with the updated object.
This file must be signed by your private key running the next command: gpg --clearsign --armor --default-key F9C96367 file . This command will generate an .asc.

gpg: using "F9C96367" as default secret key for signing

The last step is to perform the update, in this example curl is used: curl -v --data-urlencode DATA@file.asc https://syncupdates.db.ripe.net. Whois will authenticate this signature using the public key in the key-cert object.
