An Unbreakable Code Or Encription

There are large scale public encryption systems for things like telephones, but then there are small scale encryption forms that are totally unbreakable. Either for top secret need to know basis conditions, or just for fun as a novelty for any kids in the family that want to play spy games.

I will focus on useful small scale encryption because not many people control an entire populations communication technology.

The first types of encryption were simple "substitution, transposition cryptography" Here's a cryptanalysis link that explains these types of encryption in more detail. These types of cryptography use "keys" which are written on a paper to be given to the person who will receive the encoded messages. The paper looks like blocks of letters and numbers written on a piece of paper, they now use up to 64 blocks in all, as the entire key which is harder to solve. But this form of encryption is still beatable by computers.

The kryptos statue at the CIA uses the above system in part of the statue, and all of those messages in the statue have already been decoded. But in the last coded section of the staute there are too little characters to find a proper key to figure out the message. I think that in this last section it uses the following type of key for encryption, which the creator has stored in a secret location, maybe even burried somewhere to never be possible to be deciphered.

The one type of encryption that can never be cracked by a computer though is very simple. Get a book of any kind, there have been hundreds of millions of books written out there, so this shouldn't be hard. Then on each page under the page number you write a message in the margins or you highlight words or a word on that page. That is your key and to decipher it you get the page number or title or topic of the page sent in a message and then turn to that page and decode the entire message repeating that step. And because it is a unique copy of that book which exists nowhere else in the universe, then the only way to decrypt the message is with that unique book alone. This idea came from the show "Prison break" that had the bird book. simple but effective.

Also when making a password for any website I find it easiest to remember and create if I put 2 words together that don't normally go together and then put a number somewhere in the password sequence. Any password no matter what it is can still be cracked by a computer, but unless you are a prime target like a rich person or an elected official then they usually won't come after you. Just never give out any personal info in emails no matter where the email says it's from. Because companies never ask for personal info in emails.
