    How to install GnuPG on Linux? To install GnuPG on Linux. The key pair consists of two keys: Public Key and Private Key. The Public Key is used to encrypt the data, while the Private Key is used to decrypt it.

    You can share your public key, but you should keep your private key secret and safe. Since anybody with the Public Key can encrypt data, and anyone with the Private Key for that Public Key can decrypt that encrypted data.

    There are three ways to generate the key using gpg command in the terminal: The --quick-generate-key or --quick-gen-key is a simple option as it requires you to input only the user-id optionally algo, usage, and expiry date and, for the rest of the settings, defaults used. The --generate-key or --gen-key option is the standard command of GnuPG to generate a new key.

    In addition to the key, it also generates and stores a revocation certificate at openpgp-revocs. The --full-generate-key or --full-gen-key is a more user-friendly option as it generates a key pair with dialogs for all the options and, it also allows you to create keys in batch mode. You can just hit enter to continue with the default or enter the number.

    In the next prompt, it asks you for the Key size. The more number of bits, the more time it would take to generate the key. You can either enter the number of bits in the key you want or go with defaults by pressing Enter. For this tutorial, we are going with the default.

    Enter the keysize or press Enter to go with the defaults Now it will ask you for how many days, weeks, months, or years after which the Key must expire. But in case you want your Key to expire in six months, enter 1y or in terms of days. Enter Y to verify the date and proceed.

    Enter when the key must expire Now there will be several prompts asking you for some personal information to create a new user ID. Once done answering all the prompts, it will ask you to confirm it. Enter O and press Enter to proceed. Answer the prompts to create a user ID Next, it will ask you to enter a passphrase to protect your new key.

    You should carefully choose a strong passphrase, a combination of letters, numbers, and special characters strongly recommended. Enter a strong passphrase to protect your new key After entering the passphrase, it will require you to confirm it by re-entering the passphrase. As soon as you hit Enter after confirming your passphrase, it will take a moment to generate your keys. Generated new keys successfully Congratulations!

    We have successfully generated the key pair using GnuPG. Thank you for reading! Post navigation.

    How to generate PGP keys using GnuPG on Linux?

    But what is PGP and how it works? What is PGP? PGP is an encryption system developed in initially as freeware until its purchase by Symantec in when it became a licensed software that fuses two encryption standards: symmetric and asymmetric. This means that PGP uses both a public and private key and can take the efficiency from the symmetric system and the security of the asymmetric system.

    What is symmetric and asymmetric cryptography or encryption? In symmetric encryption, only one key is used to encrypt and decrypt. The benefit of this method is that it is significantly faster, but also less safe since the same key has to be shared between the sender and the recipient in a safe way. Asymmetric encryption, on the other hand, uses two keys like we explained — private and public.

    The public key is used to encrypt data, while the private one decrypts it. This method is slower, but is a lot more secure since the private one is not shared and instead remains with the recipient. How PGP Works? First, for PGP to work, it has to be present on both sides of the communication — sender and recipient. The two need to be able to share public and private keys to communicate securely.

    You can share your public key freely, but not the private one They then share the public key with you, while keeping the private PGP key for themselves With the public key they shared with you, you can now encrypt your email Once you encrypt a message with the public key, you can share it with the other person Finally, when they receive your message, they can decrypt it using their private key and read it It all sounds simple enough, right?

    The public one for encrypting and the private one for decrypting. Both sides can have the public key, but only the recipient of the message can have the private one to read the message. Step 1: Download and Install the Encryption Software Open your Terminal and type the following command: sudo apt-get install gap gnupg2.

    In the Terminal, type gpg -gen-key Next, you can choose your RSA key length, which can be from to bits long. The longer the key, the more secure it will be You can also next set for how long your key will be valid, or after what time will it expire. The user ID will be generated from your real name, email address and comment.

    Type something on your keyboard or move your mouse around to create entropy for the random number generator Step 3: Getting the Public Key Now you can obtain your public key. Step 7: Encrypting Your Message Congratulations!

    Copy this to save the file and send it to the other person Step 8: How to Decrypt the Message? Of course, to read an encrypted mail, that someone sent you, you will have to decrypt it using your decryption key. PGP uses a certificate to detect any tampering and PGP software will also determine if the certificate belongs to the right recipient. Finally, the third use PGP has is file encryption. Since PGP uses the RSA algorithm it offers a very secure option to encrypt files, in particular when used together with a good cyber threat detection solution.

    It has its advantages, but also its disadvantages. PGP is essentially unbreakable, as long as recipients keep their private keys secure. Unfortunately, this is not the case with the default PGP, which is owned by Symantec and is proprietary. On the other hand, PGP has some disadvantages that should be mentioned. The biggest of these is that it is not very user-friendly.

    Installing PGP may not be the easiest task, especially if you are not very tech-savvy. For instance, for someone to send you encrypted messages via Gmail, they need to download and install a 3rd party program like Mailvelope or FlowCrypt extensions. One of them is CTemplar: Armored Email.

    CTemplar is an end-to-end encrypted email service that uses OpenPGP to protect your emails to protect your important mail. We use the OpenPGP. This is an open source JavScript library, which allows the creation of keys for encryption and decryption. This way, not even CTemplar can decrypt your email and read its contents without knowing the actual password and neither can anyone else like the government.

    The --generate-key or --gen-key option is the standard command of GnuPG to generate a new key. In addition to the key, it also generates and stores a revocation certificate at openpgp-revocs.

    The more number of bits, the more time it would take to generate the key. You can either enter the number of bits in the key you want or go with defaults by pressing Enter. For this tutorial, we are going with the default. Enter the keysize or press Enter to go with the defaults Now it will ask you for how many days, weeks, months, or years after which the Key must expire. So we need these keys. We should provide some search terms to this option like the email address or individual name etc.

    In this example, we will search with the email address ibaydan.

    We need to provide our Public Key to the others in an open and trusted way. So Keyservers are designed to hold public keys or individuals and corporate. We will use --keyserver option to specify the key server and --send-keys to provide a fingerprint of the key we want to register. Step 1: Download and Install the Encryption Software Open your Terminal and type the following command: sudo apt-get install gap gnupg2.

    In the Terminal, type gpg -gen-key Next, you can choose your RSA key length, which can be from to bits long. The longer the key, the more secure it will be You can also next set for how long your key will be valid, or after what time will it expire.
