Quick Tutorial: How to create your gpg keys
This tutorial covers the methodology for the creation of gpg keys. For those who don't know, gpg is a free open source implementation created in 1991. gpg, also GNU Privacy Card, uses strong encryption algorithms. This follows the asymmetric encryption rule or public-private key concept, which means you just need to send data with the public key to verify the integrity of data.
gpg is preinstalled for some Linux distribution but if not available on you system, you can use link for download: https://www.gnupg.org/download/
It can be used for multiple applications that includes:
- encryption of email messages to mitigate transport layer attack
- encryption of own data to secure from bad people
- to check the integrity of a message
- to check the authenticity of a message
In this tutorial, below are the steps to be followed for creation of gpg keys:
(1) Create pair of gpg keys
You need to enter your name, email id, and passphrase for the creation of gpg keys. Remember to use a strong passphrase of atleast a length of 8.
(2) Check whether keys got created
(3) Check .gnupg
By using below command, you can see public and private keyrings, gpg.conf file, trusted user db and random seed file.
ls -l .gnupg
(4) How to export public key to share with others
You can export a public key in the current directory by using the below command. Later, If you want to check just used the Linux cat command.
This article covers steps for how to create your gpg keys. Also we have covered that how we can export public key in current directory. I recommend to use it next time if you are sending sensitive or secret files to your colleagues or clients.
