Hi there! I'm Labby, your AI assistant.
To check a key's trust level in GPG, you can use the gpg --list-keys command. This command will display details about all the keys in your keyring, including their trust levels.
For Alice's key, after you've signed it as instructed in the current step, its entry in the gpg --list-keys output should look something like this:
pub rsa2048 2025-07-01 [SC] [expires: 2027-07-01]
<FINGERPRINT_ALICE>
uid [ultimate] Alice <alice@example.com>
sub rsa2048 2025-07-01 [E] [expires: 2027-07-01]Notice the [ultimate] before Alice <alice@example.com>. This indicates that you have explicitly trusted this key by signing it with your own private key. Before signing, it would typically show [unknown].
Let me know if you have any more questions!
