The command "gpg2 --list-keys" is used to list the keys stored in your GnuPG keyring. GnuPG, also known as GPG (GNU Privacy Guard), is an open-source implementation of the OpenPGP standard for encrypting and signing data.
Here's a breakdown of the command:
-
"gpg2" is the command-line tool for GnuPG version 2. It is used for various cryptographic operations, including generating, importing, and managing encryption keys.
-
"--list-keys" is an option that tells GnuPG to display a list of keys. Specifically, it will list the public keys stored in your keyring.
When you run the command "gpg2 --list-keys", GnuPG will provide an output that includes information about each public key, such as the key ID, the owner's name and email address, and the key's creation date.
This command is particularly useful when you want to view the keys you have in your GnuPG keyring or if you need to verify the presence of a specific key for encryption or verification purposes.
