The command "pacman-key --list-keys" is used in Arch Linux to display the currently available keyring and the list of keys stored in it.
When packages are installed in Arch Linux, they are signed by their maintainers using cryptographic keys. These keys verify the authenticity and integrity of the packages. pacman-key is a utility used to manage and verify these keys.
The "--list-keys" option is used to instruct pacman-key to display the keys that are currently in the keyring. By running this command, you can see the list of trusted keys and their associated details, such as the key ID, creation date, expiration date, and key owner.
This command is helpful for verifying the status of keys in the keyring, checking for any expired or revoked keys, and ensuring the security and trustworthiness of the packages being installed in Arch Linux.
