| John and Tina generate an OpenPGP key pair (a private key and a public key) |
| John and Tina exchange their public keys, they do not share their private keys. |
| John writes a love letter and encrypts it using Tinas public key. |
| Tina gets the encrypted love letter and decrypts it using her own private key. |
| Because she has Johns public key, she can make sure the love letter is authentic. |
| Installing Kleopatra |
| The first step is to install Kleopatra using debian linux. |
sudo apt install kleopatra scdaemon |
| Or boot tailsos which comes preinstalled with Kleopatra. |
| Let's generate your keys now. |
| Start Kleopatra and click 'New Key Pair' |
 |
| Enter a false name and a false email address and click 'OK' |
 |
| OpenPGP certificate created successfully! Click 'OK' |
 |
| Now that you have some keys, let's encrypt your address using your public key. |
| See 'Notepad' in the toolbar at the top? Click on 'Notepad' and type in your address. |
| See where it says 'Recipients' in the tab above your address? Click on 'Recipients' |
 |
| Tick only the 'Sign as' and 'Encrypt for me' boxes. Now click 'Sign / Encrypt Notepad' |
 |
| You just encrypted your address using your public key! |
| Click the 'Notepad' tab to see your encrypted address. |
 |
| Copy, paste and save this encrypted address anywhere, only you can decrypt it. |
| Now let's say you need to send your encrypted address to Mark. |
| In order to do this, Mark must first provide you with his public key. |
| Mark has just sent it! |
