You will need to enter this password each time you want to decrypt a message that was sent to you. Next enter the letter O to confirm the name and email address, and you'll be prompted to enter a desired password, which can be anything you wish. However, it is what others will see when selecting who to encrypt messages to, so ensure it's something others can easily identify you by. This will start by asking your name and email address, which doesn't necessarily have to be your real name and email.
To generate a key-pair run: gpg -generate-key People can then encrypt messages to the public key, and send an encrypted message, which can then be decrypted using the private key. The public key can be freely distributed to anyone who you wish to receive encrypted messages from, while the private key is kept to yourself in a safe place. Using asymmetrical encryption, you will first generate a PGP key-pair that consists of both a public and private key. Once finished, check to ensure it's installed: gnupg - versionĪssuming gnupg was properly installed, this will display the version number.
