-Why should you even care about PGP ? Simple, you only want one person to be able to read your message, so you use PGP. You can use it when you do not trust the chat platform you are using, or the email provider, or any other form of communication with text. PGP gives you a simple way of encrypting your messages with others' public key, so that way you're sure that noone can read your messages.

Age and PGP give you a simple way of encrypting your messages with others' public key, so that way you're sure that noone can read your messages.

+You may be thinking: what's the difference between PGP and Age? PGP is a traditional way of encrypting files and messages, while Age is meant to be a more modern alternative to PGP. Age has really tiny keys (compared to PGP key sizes), uses modern cryptographic algorithms by default, while being more secure and simpler to use than PGP.
+
+### Age
+
+Let's begin by installing age first.
+
+```bash
+root@localhost:~# apt install age
+```
+
+Generate your key and output the private key into a text file. We will be outputting the private and public key to a file named `key.txt`
+
+```bash
+user@localhost:~$ age-keygen -o key.txt
+Public key: age1gme6y93jm9nx7thzfu7ma8q7t0qhxae6m4r37m23f83d3phheejs25m8h0
+```
+
+Now we can give people the public key that age gave us. It can be put publicly on your website, so that users will be able to encrypt their messages before sending it to you.
+
+The keys are so tiny, that if we want, we can encode the public key into a little QR code for people to scan
+
+```bash
+user@localhost:~$ sudo apt install qrencode
+user@localhost:~$ qrencode -o pubkey_qr.png age1gme6y93jm9nx7thzfu7ma8q7t0qhxae6m4r37m23f83d3phheejs25m8h0
