I have generated keys using GPG, by executing the following command gpg -gen-key Now I need to export the key pair to a file; i.e., private and public keys to private.pgp and public.pgp, respect. Quick steps: Create and use an SSH public-private key pair for Linux VMs in Azure.; 4 minutes to read +4; In this article. With a secure shell (SSH) key pair, you can create virtual machines (VMs) in Azure that use SSH keys for authentication, eliminating the need for passwords to sign in.

Encrypt file for other user. Decrypt other users file. Step 1: Create GPG Key Pair. The very first step is to generate key pair. Use the following command to generate gpg key pair.

GPG includes the tools you need to use public key encryption and digital signatures on your Linux system. You can figure out how to use GPG gradually as you begin using encryption in Linux. The information you find here shows some of the typical tasks you can perform with GPG to protect your Linux system.

How to Generate the key pair with GPG in Linux

The steps for generating the key pairs are as follows:

  1. Type gpg –gen-key.

    If you’re using GPG for the first time, it creates a .gnupg directory in your home directory and a file named gpg.conf in that directory. Then it asks what kind of keys you want:

  2. Press Enter for the default choice, which is good enough.

    GPG prompts you for the key size (the number of bits).

  3. Press Enter again to accept the default value of 2,048 bits.

    GPG asks you when the keys expire. The default is to never expire.

  4. If the default is what you want (and why not?), press Enter.
  5. When GPG asks whether you really want the keys to never expire, press the Y key to confirm.

    GPG prompts you for your name, your email address, and a comment to make it easier to associate the key pair with your name. Case key generator cs go.

  6. Type each piece of requested information, and press Enter.
  7. When GPG gives you a chance to change the information or confirm it, confirm by typing o and pressing Enter.

    GPG prompts you for a passphrase that protects your private key.

  8. Type a long phrase that includes lowercase and uppercase letters, numbers, and punctuation marks — the longer the better — and then press Enter.

    Be careful to choose a passphrase that you can remember easily.

    GPG generates the keys. It may ask you to perform some work on the PC so that the random-number generator can generate enough random numbers for the key-generation process.

How to exchange keys using GPG in Linux

Gpg Create Key

If you’re an administrator, protecting your Linux system should always be at the top of your mind. To communicate with others, you have to give them your public key. You also have to get public keys from those who may send you a message (or when someone who might sign a file and you want to verify the signature). GPG keeps the public keys in your key ring. (The key ring is simply the public keys stored in a file, but the name sounds nice because everyone has a key ring in the real world, and these keys are keys of a sort.) To list the keys in your key ring, type

To send your public key to someone or to place it on a website, you have to export the key to a file. The best way is to put the key in what GPG documentation calls ASCII-armored format, with a command like this:

This command saves the public key in ASCII-armored format (which looks like garbled text) in the file named kdulaneykey.asc. You replace the email address with your email address (the one you used when you created the key) and replace the output filename with something different.

After you export the public key to a file, you can mail that file to others or place it on a website for use by others.

Generate

When you import a key from someone, you typically get it in ASCII-armored format as well. If you have a us-http://www.us-cert.gov/pgp/email.htmlin a file named uscertkey.asc, you import it into the key ring with the following command:

Use the gpg --list-keys command to verify that the key is in your key ring. Here’s what you might see when typing gpg –list-keys on the system:

The next step is checking the fingerprint of the new key. Type the following command to get the fingerprint of the US-CERT key:

GPG prints the fingerprint, as follows:

At this point, you need to verify the key fingerprint with someone at the US-CERT organization.

If you think that the key fingerprint is good, you can sign the key and validate it. Here’s the command you use to sign the key:

GPG asks for confirmation and then prompts you for your passphrase. After that, GPG signs the key.

Because key verification and signing are potential weak links in GPG, be careful about what keys you sign. By signing a key, you say that you trust the key to be from that person or organization.

How to sign a file with GPG in Linux

You may find signing files to be useful if you send a file to someone and want to assure the recipient that no one tampered with the file and that you did in fact send the file. GPG makes signing a file easy. You can compress and sign a file named message with the following command:

To verify the signature, type

To get back the original document, type

Sometimes, you don’t care about keeping a message secret, but you want to sign it to indicate that the message is from you. In such a case, you can generate and append a clear-text signature with the following command:

This command appends a clear-text signature to the text message. Here’s a typical clear-text signature block:

When a message has a clear-text signature appended, you can use GPG to verify the signature with the following command:

Encrypting and decrypting documents with GPG in Linux

To encrypt a message meant for a recipient, you can use the --encrypt (or -e) GPG command. Here’s how you might encrypt a message for US-CERT by using its GPG key:

The message is encrypted with the US-CERT public key (without a signature, but you can add the signature with the -s command).

When US-CERT receives the message.gpg file, the recipient must decrypt it by using US-CERT’s private key. Here’s the command that someone at US-CERT can use:

Then GPG prompts for the passphrase to unlock the US-CERT private key, decrypts the message, and saves the output in the file named message.

If you want to encrypt a file that no one else has to decrypt, you can use GPG to perform symmetric encryption. In this case, you provide a passphrase to encrypt the file with the following GPG command:

Gpg Generate Key Pair Linux Code

GPG prompts you for the passphrase and asks you to repeat the passphrase (to make sure that you didn’t mistype anything). Then GPG encrypts the file, using a key generated from the passphrase.

To decrypt a file encrypted with a symmetric key, type

GPG prompts you for the passphrase. If you enter the correct passphrase, GPG decrypts the file and saves the output (in this example) in the file named myfile.
