Tool to automatically solve cryptograms. A cryptogram is a short piece of encrypted text using any of the classic ciphers. Usually it is simple enough that it can be solved by hand. The most common types of cryptograms are monoalphabetic substitution ciphers, called Aristocrats if they contains spaces or Patristocrats if they don't. Another common name is cryptoquip.
Note: You can use the tool below to solve monoalphabetic substitution ciphers. There are many other types of cryptograms. This Cipher Identifier Tool will help you identify and solve other types of cryptograms.

- The most common cryptograms are monoalphabetic substitution ciphers.
- The American Cryptogram Association (ACA) uses the names Aristocrat (a cryptogram that includes separators between words) or Patristocrat (a cryptogram that doesn't separate words). In both cases, a letter is not allowed to be substituted by itself.
- Cryptograms originally were intended for military or personal secrets. The first know usage for entertainment purposes occured during the Middle Ages.
- Instead of spaces, a letter like X can be used to separate words.
- Frequency analysis can be used to find the most commonly used letters.
- A Caesar Cipher is a special kind of cryptogram, in which each letter is simply shifted a number of positions in the alphabet. It can easily be solved with the Caesar Cipher Tool.
- A ROT13 Cipher is similar to a Caesar Cipher, but with a fixed shift of 13 letters. It can easily be solved with the ROT13 Tool.
