This should be done as soon as you make the key pair, not when you need it.

There is an easy way of doing this with the GPG software. You need to have a way of invalidating your key pair in case there is a security breach or in case you lose your secret key. Open up a new terminal and SSH into the server again to set up haveged on your server. To generate additional entropy more easily, you can use a tool called haveged. This process may take a long time depending on how active your system is and the keysize you selected. GPG needs this entropy to generate a secure set of keys. Entropy describes the amount of unpredictability and nondeterminism that exists in a system.

Enter passphrase: Enter a secure passphrase here (upper & lower case, digits, symbols)Īt this point, gpg will generate the keys using entropy.

Change (N)ame, ©omment, (E)mail or (O)kay/(Q)uit? O.

Email address: your_email Comment: Optional comment that will be visible in your signature.

If you are just testing, you may want to create a short-lived key the first time by using a number like “3” instead.)

Key is valid for? 1y (expires after 1 year.

Please select what kind of key you want: (1) RSA and RSA (default).

This will take you through a few questions that will configure your keys: You can do this by issuing the following command: To begin using GPG to encrypt your communications, you need to create a key pair.

On CentOS, you can install GPG by typing:

If for any reason GPG is not installed, on Ubuntu and Debian, you can update the local repo index and install it by typing: GPG is installed by default in most distributions. The public key that the receiver has can be used to verify that the signature is actually being sent by the indicated user.

Validate the Identity of the SenderĪnother benefit of this system is that the sender of a message can “sign” the message with their private key. So in this scenario, each party has their own private key and the other user’s public key. If both of the parties create public/private key pairs and give each other their public encrypting keys, they can both encrypt messages to each other. This would allow for a one-way message transfer that can be created and encrypted by anyone, but only be decrypted by the designated user (the one with the private decrypting key). That way, you can freely distribute the encrypting portion, as long as you secure the decrypting portion. The idea is that you can split the encrypting and decrypting stages of the transmission into two separate pieces. To get around this issue, GPG relies on a security concept known as public key encryption. Ensure That Only the Intended Party Can Read

Many schemes that attempt to answer this question require, at least at some point, the transfer of a password or other identifying credentials, over an insecure medium.

How Public Key Encryption WorksĪ problem that many users face is how to communicate securely and validate the identity of the party they are talking to. We will be using an Ubuntu 16.04 server for this demonstration, but will include instructions for other distributions as well. In this guide, we will discuss how GPG works and how to implement it.

This allows for the secure transmission of information between parties and can be used to verify that the origin of a message is genuine. GPG, or GNU Privacy Guard, is a public key cryptography implementation.
