Encryption works. Properly implemented strong crypto systems are one of the few things that

you can rely on. Unfortunately, endpoint security is so terrifically weak that NSA can frequently

find ways around it.

– Edward Snowden, answering questions live on the Guardian's website

The NSA has been in the news a lot lately, and it's downright scary just how much privacy we've given up. It doesn't have to be that way, though. There are tools out there that will let you take your privacy back. One of the most popular and widely available strong crypto systems is PGP encryption which you can use to secure email and forum messages. It's also military grade encryption, so how often do you get to play with something like that?

If you don't have your own PGP key pair you're an Obama-loving commie.

PGP stands for "Pretty Good Privacy" (which is kind of a joke, because it's actually really strong encryption). It's a form of encryption known as 'public key' encryption or 'asymmetric key' encryption. When most people think of encryption, they think of scrambling data in a way that only a single password or key will unlock it. That type of encryption could work for things like email or messaging if you had the chance to share the key with the recipient beforehand in person, but if you've never met them and are worried about an eavesdropper watching your email or PM, sharing the key in a way to guarantee privacy becomes impractical. That's where public key cryptography comes in.

Public key cryptography was designed to facilitate communications between people who have never met and wish to communicate privately over a an insecure channel such as email. In public key crypto, each user gets two keys instead of just one. They're long strings of mathematical numbers that are related in such a way that they have a special property: whatever you scramble with one key, the other will unlock, and vice-versa. What's more, they're the only keys that can do this --if you can unscramble a message with one key, you know it was scrambled with the other (and vice-versa). Each user will publish their public key while keeping their private key, well, private.

Suppose I wish to send a message to Bob. I want Bob to be sure that it is actually me that sent it, and I want Bob to be the only person who can read it. Each of us have already generated a pair of PGP keys (more on this below) and published our public keys (by say, posting them in a thread on AR15.com). I first look up bob's public key and import it into my PGP program. I write my message, and then I sign it with my private key. Signing it scrambles it with my private key, but anyone can use my public key to unscramble it. This shows Bob, or anyone who has access to my signed note, that I was the one who wrote it because I am the only one who knows my private key. Now I take my signed message and I encrypt it using Bob's public key. Once I do this, nobody but Bob (not even me) can unscramble it because Bob is the only one with his private key. Then I send the message to Bob via email, PM, or I could even post it in a thread that Bob will see. Bob will then use his private key to unscramble the message, then verify with my public key that I am the author.

The above process sounds a bit complicated, but once you practice a couple times it's as easy as pie. It's also really easy to practice.

GETTING STARTED

We'll be using an open source implementation of PGP which is based on the OpenPGP standard. The Free Software Foundation developed its own OpenPGP-compliant program called GNU Privacy Guard (abbreviated GnuPG or GPG). In the crypto world open source is very important. It's pretty easy to develop a crypto system that you're not smart enough to crack. The trick is developing a system that nobody else can crack either. The German Enigma cipher box had a flaw which allowed Alan Turing to break the code and let the allies read all the nazi mail. By publishing all the algorithms and source code of a crypto system we let all the Alan Turings in the world to try their hardest to break the system. If they do, then we know we have to build something better. The particular GnuPG program we will be using is called gpg4usb. It's a small, self-contained program you can run right from a USB stick. It works for Windows and Linux. (There are Mac based PGP programs too, such as GPGTools.)

Find it here: http://gpg4usb.cpunk.de/about.html

Tutorials and guides: http://gpg4usb.cpunk.de/docu.html

(further reading to harden your endpoint security: https://pressfreedomfoundation.org/sites/default/files/encryption_works.pdf )

Follow the download link and save the zip file. In the zip file is a single directory which holds the entire gpg4usb program; there is no install. You can extract that directory to any location on your PC or on a USB drive. To run gpg4usb, open the folder and run the start_windows file.

When run the first time it will look like the screen below, with a First Start Wizard which will help you generate your key pair.

Leave the language as System Default and click the next button. Click on the 'create a new keypair' link in the window.

Clicking the 'Create New Key' button brings up the window below:

At this point it should be noted that the name and email address you use here for generating this key will be embedded into the public key in an unencrypted form, and will be used in your PGP program to identify the key. When you publish your public key (for example, by posting it to a forum), anyone will be able to import your public key into their PGP program and read the name and email attached to it. When you generate your key, I'd suggest using your profile name, and your profile name @ AR15.com as a bogus email address, unless you're comfortable putting your email address in the open, in which case you can use your normal email address.

I'll chose for my key to never expire and I'll leave the keySize at the default 2048 bits. 2048 is the minimum you should use right now, with 4096 offering much more secure, but is twice as long (your public key, which you post, will be more cumbersome).

You will need to choose a password which will be used each time you access your private key (the private key is scrambled on your hard drive and accessed with this password). So each time you want to decrypt a PGP message someone has sent you, or sign a message you're going to send, you'll need to enter this password. Google password strength and follow the directions to pick a strong password for your private key.

After I've filled out the fields they look like this (I forgot to check 'Never Expire' before taking this screenshot):

After hitting 'ok' your computer will generate your keys. It could take a minute depending on how fast your computer is. Then you can hit 'finish.'

Now I have the gpg4usb user interface open. On the right I have my keys and on the left I have my text windows. Above the text windows are all the different encrypt/decrypt etc. options I can choose.

The keys on the right include the pair I just generated and also the public key for the gpg4usb developers. Now would be a great time to play around with your key-pair by signing, encrypting, decrypting, and verifying a message.

Step 1: Sign a message

First, we write a message. For this example, I've selected a few choice stanzas from the mcuzi rant. I then select my key-pair, and then hit 'Sign.'

After entering my password, the text will be converted into the signed text. You can see now it has a header and footer, as well as some gibberish at the bottom, which represents the signature based on my private key. To generate the signature, PGP takes all my text and grinds it up in a specific way to produce a unique number called a hash. By changing only one letter in my text, the hash value would be completely changed. For all intents and purposes, each body of text I may write would have one unique hash. PGP then encrypts this hash value with my private key. Now everybody can check the signature with my public key and verify it was signed by my private key. In fact, I can do this now by clicking on the 'Verify' button above. gnu4pgp will hash the message, decrypt the signature with my public key, and compare the two hashes. If they match, it will show the verification on the bottom of the screen. Clicking on the 'Details' button gives me more info about the signature:

It should be noted that signing a message includes the date and time as well as the Name and Email you used to create your key pair inside the signature.

Now, as a check to make sure gpg4usb is really checking the signature, I'm going to delete one single character from my text and then hit 'Verify.' PGP now tells me that the signature for the text is not correct:

(Note the red box was added by me in Paint, and isn't a feature of the PGP. The original text can't be back-generated from the signature.)

By adding back the character I can re-verify and see that the signature now matches the message. So, now we can encrypt the message. Normally, we would encrypt the message with the recipients public key (say, Bob), but for now we'll encrypt it with our own public key so we can look at decrypting it in another step.

To encrypt the message we select our key pair from the list of keys on the right and hit 'Encrypt.' Now we have this:

This entire text makes up our encrypted PGP message. If I had used Bob's public key instead of my own, I could now send this text in its entirety (including the --BEGIN... and --END... header and footer) to Bob via email, PM, or posting it to a forum. If I mess up and delete any of the characters from the message (especially from say the header), then the message won't be valid to be decrypted by the correct private key anymore.

Now pretend this message is from Bob, who encrypted it with our public key and sent it to us in a PM on the forum. We would select all the text, including header and footer in our browser PM window, and copy it. Then open up gpg4usb and paste the encrypted text into a fresh text window (File->New for a new text window if needed). Hitting the 'Decrypt' button will ask us for our password to uncover our private key, and then voila! Our message appears in plain text. Note that our key doesn't have to be selected--the name, email address, and fingerprint from our public key is included in the encrypted message. Gpg4usb will check our keys and see if we have the corresponding private key (which we do) and then ask us for our password to decrypt the message, after which we see our message! We can click 'Verify' too, and it will check the signature with our public key (Bob's public key if the message were from Bob) and verify it. I would now suggest playing around with the text editors by writing a message, signing it, encrypting it with your public key, decrypting it, and checking the signature. See what happens if you delete a character from the message and how that effects the signature verify or the decryption.

Also, try signing your message with the gpg4usb-project key. It won't let you because you only have the public key (private keys are for signing and decrypting). Try encrypting your message with the pgp4usb-project public key. You should notice that you cannot now decrypt it because you don't have the corresponding private key. Did you keep a copy of your message? Remember, once you encrypt a message with someone else's public key, you won't be able to decrypt the message. (gpg4usb has an undo function which will undo editing operations including the encrypt function in a word window in case you forgot to save a copy for yourself. This is done with program memory which stores a copy of your message in plain text, not by decrypting it.) Some PGP programs integrated into an email program will automatically encrypt a copy of the message with your own public key as well as the recipient's public key so you'll have a copy for your records. gpg4usb can do this too. Simply check your own key as well as the recipient's public key. Now either your private key or the recipient's private key can unlock the message. So if you wish to keep a copy for yourself, you can either store a clear text copy on your computer (not recommended if you are sending something sensitive), or encrypt the message with both your and the recipient's public key and save a copy for yourself. Be aware that while the message is in transit out in the world, it is protected by the strength of your public-private key pair. If a bad guy gets a hold of your computer, your messages and private key are protected by the strength of the password you chose which hides your private key (so if you're doing something sensitive, google password strength and follow the directions to pick a strong password for your private key).

So, now that we've played around a bit with our own key-pair, lets look at importing somebody else's public key so we can send them private messages.

Our buddy Bob has posted his public key to the Arfcom PGP Public key thread. In his post sig line we see he has a link to his public PGP post. We follow it and we see his his post which starts with "-----BEGIN PGP PUBLIC KEY BLOCK-----" followed by a bunch of gibberish. In order to load Bob's public key into our PGP program, we need to copy all of that, including the header and footer. Selecting all the text and then a simple right-click-copy or ctrl-c works great. Then we bring up gpg4usb and paste it into a clean text window (File->new if you need a new one). You can import directly from the clipboard, but I prefer to paste it into a new text window so I can make sure I got the whole key, including header and footer). Then click the 'Import Key' button, and select 'Editor.'

If we did the copy/paste/import correctly, we'll get a window showing our new key's info. Hit okay, and now we have Bob's public key (or jakjakman's key, in this case).

For the Arfcom PGP club, the first key you'll want to import is the AR15.com PGP club key. It's posed directly below this post. Then you'll be able to send me encrypted messages and I can respond, so you can test it out. You can also import other member's keys and send them messages as well. A final goal for AR15.com would be for every PM interaction with other Arfcom members to be done through PGP encryption, especially when using the equipment exchange. You can send messages by simply responding and pasting the encrypted text into the window and hitting reply, or you can send them via PM.

Post your public keys to this thread: http://www.ar15.com/forums/t_1_124/1527552_.html

(you can post them here, but it could get a bit cluttered with with both keys and messages.)

Have fun!!

The short version.

You give everyone your "public key". They encrypt their messages to you with that "public key' and then they send their encrypted email messages to you.

You open the sent messages with your "private key" that only you know.

I work for a company whose main client is the US gov. Whenever we sub-contract or communicate with other companies on our contracts, we use PGP encryption. It's not just for the baddies.

If anyone fancies themselves a libertarian, they should understand and be able to use public-private key cryptography to communicate.

The email address you write in when creating the public key can be bogus. The one for the Arfcom PGP club is bogus.

Oh I know that, I have a few that are: "TorPM:<derpwebusernamehere>". I just have a feeling a few have very interdasting files to share, and I'd like a good way to get them.

The only thing that is important is to keep the private key safe.

Rather than cracking PGP the goal is just to simply steal the private key.

Most people lack the discipline to keep the key password protected with a proper password.

I remember reading about a method that was being tested to teach people long passcodes, through muscle memory. They would be given a pattern(guitar-hero style) over and over, 30 digits long, until they had it memorized. It was something like 4 or 5 buttons, so they really wouldn't be able to tell you what the passcode is, only to duplicate it.

I guess you could create a passcode-entry device that uses a unique encoding algorithm for each device, and train a passcode using one. Finally, include a wipe button that, if pressed, overwrites the memory on the device that is in charge of the encoding algorithm, so you would no longer be able to be forced to enter your code. It would beat rubber-hose decryption, but you might have a hard time convincing 'them' of that.

Very true. This is the other half of Snowden's quote.

"Encryption works. Properly implemented strong crypto systems are one of the few things that

you can rely on. Unfortunately, endpoint security is so terrifically weak that NSA can frequently

find ways around it."

Luckily, there are ways to harden up the endpoints too. This document gives a good overview on how to do just that: https://pressfreedomfoundation.org/sites/default/files/encryption_works.pdf

In the meantime, public-private key cryptography can be tricky to get the hang of, but offers an incredible boon to those who wish to communicate privately. One step at a time.

Sounds very secure. A bit hard to do with someone you've never met over the internetz though. Ironkeys aren't very cheap, either.

Suck on that, NSA!

Wiping a disk to do a encrypted LVM volume. Maybe after that. This is taking for freaking ever.

Yes, there are iPhone aps that can do this from your iPhone. The one I have on my iPhone is oPenGP. This one won't generate your initial key pair, you'll still have to do that on your pc with something like gpg4usb. Then you can transfer your key pair to your iphone oPenGP ap.

So far there's a thread here I just started with a couple keys in it: http://www.ar15.com/forums/t_1_124/1527552_post_PGP_keys_here.html

Down the road that'd be cool to have an ARFcom PGP public key server.

Maybe I overlooked this (probably) but how do I get my public key after generating a key, so I can give it to others?

Click the manage keys button.

Select your key and click export to clipboard, then you can just paste it.

In most PGP programs there will be an option to "export public key" or something like it. for gpg4usb, click on the 'Manage Keys' icon at the top. In the window that pops up, check the box next to your key pair and then click "Export to Clipboard." Now the key is in your copy/paste clipboard, and you can paste it in a forum post or email, etc.

If you like you can past it in this thread: http://www.ar15.com/forums/t_1_124/1527552_post_PGP_keys_here.html

In.

We could also do physically distributed one-time-pad codebooks to trusted members... I suggest each Hometown Forum do it separately, to limit the effect of any one compromise...

Oh, for Mac users - check out GPGTools. I built it from source, but as far as I know the binaries are trustworthy.

It's nice, in that I can type what I want to encrypt in the reply window, right click, select "Encrypt", choose recipients, and it replaces it with the encrypted text.
