Gnupg mac
This is the newly generated encrypted form of our message. A new file will be created, and if you open the file in a text editor you will see something similar to: -BEGIN PGP MESSAGE- hQGMAzCBDnMltq9zAQv/ZHQ3tJq+feazdLa3thzQE2bhPx+7WaPZcX7SdkoyuKvw 9faS7h9OwBjQ4vUyDKespSq3ZNf1pRgNoXijjs3MGEi5IsYxDgNWo1ZJv2qQqp36. Most likely this will ask you to confirm that you indeed wish to encrypt to this public key, and you can just hit the Y key to agree.
-a states we want the output in ASCII or plain text format.-e specifies that we're encrypting data.Let's quickly break down the above command: Within terminal and inside the directory where message.txt resides, run the command: gpg -e -a -r message.txt When encrypting messages, you will only need the email address of the recipient.įor example, you may need to send some sensitive information to your web designer, who's PGP key you have already imported under the email address Type out the desired message and save it to a text file, e.g. The only pieces of information you need to take notice of there is the name and email address of the entry, which states the owner of that key. You will see a bunch of entries that look similar to below, one for each key available within gnupg: pub rsa3072 8978168C4E79A08553E5789CD42A4A4EC1468CFE uid Matt Dizak At any time you may view a list of all PGP keys currently available within gnupg: gpg -list-keys This will import the person's public PGP key into gnupg allowing you to begin sending encrypted messages to them. When you receive someone's public PGP key, save the file to a directory and accessing terminal from the same directory, run: gpg -import key.asc Same as you can now share your public key with others, people will also share their public keys with you. Send this file to anyone who you wish to be able to send you encrypted messages. You will now see a new file in the current directory named mykey.asc. Within terminal run the command: gpg -a -export -e > mykey.ascĮnsure to change the email address you supplied when generating your PGP key. Now that your key-pair is generated, you need to export the public key to distribute to others.
GNUPG MAC FREE
Feel free to navigate away from terminal for a couple minutes and do something else until you see a message saying your key has been successfully generated. Once you've confirmed the password, it will begin generating your new PGP key-pair, which can take a few minutes to gather enough entropy/random data from your computer.
GNUPG MAC PASSWORD
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.
GNUPG MAC INSTALL
Otherwise, you can install gnupg by running: sudo apt-get install gnupg2 If it displays the version of gnupg you're currently running (should be v2+), then you're all set and can move to the next section. Within terminal, run the command: gnupg -version First check whether or not gnupg is already installed.
