apt-key: Add a key to the trusted keystore.

apt-key

$ apt-key add ${public_key_file-asc}

try on your machine

This command is used in a Linux terminal to add a public key to the apt keyring. The public key is specified by the ${public_key_file-asc} parameter, which represents the filename and path of the public key file in ASCII armor format.

The apt-key command is typically used in Debian-based systems to manage APT (Advanced Package Tool) repositories and add trusted keys. The add subcommand is used to add a new public key to the keyring.

In this specific command, the ${public_key_file-asc} is a placeholder for the actual filename of the public key file. The format of the key file is expected to be ASCII armor, which is a textual representation of the public key in a human-readable format.

To use this command, you would need to substitute ${public_key_file-asc} with the actual path and name of the public key file you want to add. For example, if the file is named "my_key.asc" and is located in the current directory, the command would be: apt-key add my_key.asc.
