How do I decode ciphertext? To decrypt, take the first letter of the ciphertext and the first letter of the key, and subtract their value (letters have a value equal to their position in the alphabet starting from 0). If the result is negative, add 26 (26=the number of letters in the alphabet), the result gives the rank of the plain letter.
What is cryptogram code? A cryptogram is a kind of secret code. The formal name for this particular kind of code is a simple substitution cipher. Strictly speaking, a code is a method of disguising a message that uses a dictionary of arbitrarily chosen replacements for each possible word.

What are the rules of a cryptogram?
The Basic Cryptogram Rules. A cryptogram is a puzzle where a phrase has been encoded. You can use a cipher to keep track of your decoding. Each letter is represented by a different letter (or number or symbol). There is only one possible solution and each letter cannot decode to itself (so H cannot be H).

What kind of codes are there?

Is code and cipher the same thing?
Ciphers vs. Codes. Codes substitute arbitrary symbols—typically, letters or numbers—for the components of the original message. Ciphers use algorithms to transform a message into an apparently random string of characters.
