A cryptogram is a message or text that has been encoded using a cipher or puzzle. The ciphertext is the encoded message, while the plaintext is the original message. Cryptograms can be used for a variety of purposes, including communication secrecy, data security, and entertainment.

There are many different types of cryptograms, but some of the most common include:
- Substitution ciphers: These ciphers replace each letter of the plaintext with a different letter, symbol, or number. A common example of a substitution cipher is the Caesar cipher, which shifts each letter of the plaintext three places down the alphabet.
- Transposition ciphers: These ciphers rearrange the letters of the plaintext without changing them. A common example of a transposition cipher is the rail fence cipher, which writes the plaintext in rows that are then rearranged.
- Combination ciphers: These ciphers use a combination of substitution and transposition techniques.
Cryptograms can be solved by a variety of methods, including frequency analysis, pattern recognition, and logical deduction. There are also a number of tools and techniques that can be used to aid in solving cryptograms, such as cipher wheels and code tables.
