It is now very important that all internet-using people know how to communicate securely, even over insecure channels like gmail, and with no fear of being spyed upon by e.g. the NSA. Fortunately there is a way to do this. It is called PGP.
This thread is a brief explanation of PGP and how to use it, with an interactive component. Your challenge is to send me an encrypted message!
HOW PUBLIC KEY CRYPTO WORKS (VAGUELY)
Everyone makes their own public key and private key. You keep the private key to yourself, but advertise the public key widely (website, email signature, etc.), so that anyone who wants to message you securely uses your public key. The encrypted message can only be read by the person with the associated private key, namely, yourself.
Remarkably, this allows you to communicate securely with complete strangers who you've never met before, without exchanging a secret key.
HOW TO DO IT (in 5 minutes)
1. First, download the software. By googling "PGP client" you can find an assortment; I prefer gpg4win for Windows. Macs might try GPGtools. My tutorial will focus on gpg4win, but the steps will be similar for other clients. Worst case scenario, you have to read someone else's tutorial.
2. Open Kleopatra.
3. File, New Certificate, create an OpenPGP key pair.
4. Enter your details, and in Advanced Settings chooseRSA 4096 bit (for maximal security).
5. Create the key. Make sure to use a long (>16) password which is generated randomly using special characters. random.org has a generator you can use, but I recommend KeePass as a generator and a way to store your passwords (so no memorization needed).
6. Now, from my experience you may want to close and restart Kleopatra at this point, because usually it doesn't immediately list your new key. You want to see, in the main interface, the key with your name, email, etc.
What to post here (to complete the challenge)
1. First, you want to right click the key you've created, and click "Export Certificate". This makes an .asc text file (which may be opened e.g. with WordPad) containing your public key. It will look like the block of text at the bottom of this post. This is the public key; other people need to see it in order to communicate to you securely. Now, post your public key in this thread (as I've done).
2. Second, you need to practice by sending me a message. To do that, copy/paste my public key (which is below) into a blank text document, and save it as a .asc file. Then, in Kleopatra, go to Import Certificates, and select that file. Once my key is imported, you may send me an encrypted message. First, type the message you want into a .asc file. Then in Kleopatra, go to file, sign/encrypt files. Choose the file, choose encrypt and select "Text output (ASCII armor)", next, select my name as who you want to encrypt to. Voila! Kleopatra will make a file which contained the encrypted message. Place the encrypted message
3. If you did everything correctly, I am the only person in the world who can read your message (with the private key corresponding to my public key). When I read the message, I will write a response and send an encrypted message back using your posted public key. To read it, you will go to File, Decrypt/verify files, and the rest should be obvious by now.
I'm anxiously awaiting your responses! Please tell me if anything is unclear in the above, or if you have any questions.
Here is my public key:
