The object of it is to solve the puzzles by selecting letters and placing them onto the crypto grams map. You can add your own words or sentence into the list. Also you can print the puzzle and present it to your friends or send flash software by e-mail. This program is absolutely free. Fun for all ages and skill levels.

What is the Cryptography

There are two kinds of cryptosystems: symmetric and asymmetric. Symmetric cryptosystems use the same key (the secret key) to encrypt and decrypt a message, and asymmetric cryptosystems use one key (the public key) to encrypt a message and a different key (the private key) to decrypt it. Asymmetric cryptosystems are also called public key cryptosystems.

Symmetric cryptosystems have a problem: how do you transport the secret key from the sender to the recipient securely and in a tamperproof fashion? If you could send the secret key securely, then, in theory, you wouldn't need the symmetric cryptosystem in the first place -- because you would simply use that secure channel to send your message. Frequently, trusted couriers are used as a solution to this problem. Another, more efficient and reliable solution is a public key cryptosystem, such as RSA, which is used in the popular security tool PGP.

How to solve a cryptogram

See if you can recognize some of the partially solved words. Let's say there is a DIS4. That might be either DISH or DISK. Now take a look at other words. If you find one where substituting 4 with either an H or a K makes any sense, then that's probably it.

Take a look at the hint if one is provided. A hint is a word or words that are written in plain letters. If you can guess a word next to the hint, you will have cracked those numbers. For example, if there is CHEWING 123, you might guess that 123 is GUM. Sometimes the hint word is repeated somewhere in the cryptogram. See if you can find a word with the same pattern of characters as in the hint.

Short words can sometimes be guessed, because there are not too many possibilities. Here are some common short words:

  • one letter: a, i, (o)
  • two letters: of, to, in, is, it, be, as, at, an, by, he, on, or, so, if, no
  • three letters: the, and, for, are, but, not, you, all

You can use a frequency analysis technique. The "E" letter is the most common letter in the English language. If you count the numbers and find that the letter "S" is the most frequent one, then the "S" may be an "E". You can then do the same with other letters. However, since the secret messages are not very long, this method may be inaccurate, and you will have to try other letters of similar frequency as well. Complete order of letter frequencies is: E T A O N I R S H D L U C M W F Y P G B V K J X Q Z.
