Copy paste below, or go to link. My commentary:
NSA surveillance of everyone means that you must always assume a third person is listening to any electronic communication, or even if you are in a room with a cell phone that has it’s battery in it.
This also means that the National Security State has put policing on Auto-Pilot, in order to cut staff and pensions. Existing “intelligence police” are relying heavily on SIGINT and not so much on HUMINT.
You can be fairly certain that your electronic communications are not being listened to in real time; they are being vaccuumed up for later use. So it’s simple enough, if inconvenient, to communicate in a way that, when they go to fetch your cell phone call or text from June 22, 2015, it is totally useless.
It’s not PGP either. How do we know PGP is secure? I don’t know.
This method is clearly unbreakable on it’s face, as long as the Excel file isn’t captured or the NSA doesn’t have some way of knowing the number randomizations in Excel. Number randomizations are seeded with the time of the execution of the program, so I don’t think so, but this is a potential vulnerability. You could input the number randomization yourself. I invented this method myself, and I’m surprised no one else came up with it.
1. Google for a big list of words on the internet, and copy/paste into a huge Excel column, Column A. Go for 20,000 words, and add in your own words as needed if they aren’t there.
2. Do the random number function for 5 digit numbers for 25,000 rows for column B. Do extra numbers so you have room for growth. Having some unmatched numbers is not a problem.
3. Share this Excel file with your communicant. Ideally, keep the Excel files on computers that never connect to the internet — that don’t even have network cards or wireless radio cards. But even if you have the Excel file on an internet connected computer, the NSA isn’t collecting in real time and goign to say, “Oh, this citizen is using encrypted communication, let’s hack his computer and find out what he’s up to!” It’s just unlikely.
4. To create a message, use the find function to find your word, and write down the 5 digit number next to it. Rinse, repeat, until message is complete, then send the string of numbers to your communicant. Preferably by a different device than the computer — like a text with burner phones. Years later, NSA wants to retrieve your communications — it’s just strings of digits. Oops! Ha ha!
The NSA is spending it’s resources collecting noise and what Russians call Kompromat, but anyone who is determined to keep their communications secure from them can succeed easily enough.
As an aside, I don’t bother doing this myself because I live a very bourgeouis and law abiding life. But I just wanted people to not be too freaked out over the NSA. It can be defeated easily enough, and my method is only one of many.
