How to correctly add PGP key to torrc ContactInfo?

I’ve been trying to add my PGP key to the torrc file under the Contact Info but doing so keeps giving me the following error message: [warn] Failed to parse/validate config: Unknown option '-----BEGIN PGP PUBLIC KEY BLOCK----- <HASH> . How can I include my PGP key so that it doesn’t cause errors?

Make sure your ContactInfo is one line. To include a gpg/pgp-key you may use the fingerprint of it, if you uploaded it somewhere where it might be found by others…

An example with gpg: is here: Relay Search

In short: use the hash value, not the public key itself.

Thanks for sharing the example! I looked into how to make a PGP hash but didn’t understand the process and don’t know of a way to test if it works. Would you happen to know how to correctly create a hash value?

There’s no need to make a hash.
If you have a PGP key, then list it and use its hash. If you do not have a PGP key then skip that entry in contact info entirely.

Try gpg --list-keys

Here’s the output:
[root@fedora-39 ~]# gpg --list-keys gpg: directory '/root/.gnupg' created gpg: /root/.gnupg/trustdb.gpg: trustdb created

I have the public PGP file downloaded onto Documents so I tried importing from there but got an error:

[root@fedora-39 ~]# gpg --import /home/user/Documents/publickey.lovespreader444@protonmail.com-7c3a87c8d9e6c94c5a7c29e60fee4035ec52cacb.asc
gpg: can't open '/home/user/Documents/publickey.<emailaddress>-<text>.asc': No such file or directory
gpg: Total number processed: 0

I replaced the email and following portion of the file name for this post.
