Short guide about how to use PGP
As I promised, I made a short guide about PGP encryption. Shortly, PGP is a computer program used to encrypt and decrypt data, making it impossible for someone else to decrypt it without a key.
There are two things you can do with PGP: send an encrypted message so only the sender can see it and to receive and encrypted message and you being the only one who can view it.
So, how to use this amazing technology called PGP? First you need to download a PGP program. I recommend you gpg4usb from http://www.gpg4usb.org. Just open the site and click Download. After the download is complete, you will see a zip archive named gpg4usb-0.3.3-1.zip (or other numbers, depending on version). Extract the archive, and you will have the following folder.

1. How to receive an encrypted message?
Open start_windows from that folder. Choose your language and click Next until the small window closes. You will see the following window:
In order to receive an encrypted message, you need to have a private key and public key. Private key is used to decrypt the message, and the public key will be used to encrypt the message. The sender needs your public key to send you the encrypted data.
We need to make you a new key. So, click on Manage Keys. In the new window that appeared, click on Key and then Generate Key. Enter a name, an e-mail address and a password, like you see below. You don’t need to write your real name or e-mail, you can write anything you want.

Wait a few seconds, and Voila! Now you have your own PGP key! In the Key management window, select your key, and click Export to file or Export to clipboard, and you will have your public key, that looks like this:

Give that key to the sender. Now he can write you encrypted messages that look similar to the public key (see below in the image). To decrypt the message you just paste the encrypted message in the program, select your key, and click Decrypt.

Now, in order to send an encrypted message to this person, just write it in the program, select the person’s key from the right, and then click Encrypt. And you just send the encrypted message to the sender, because he has the private key to decrypt it.
Notice that you see a little image next to your key, in this case the first key from the list is yours and you can decrypt using it.
