A ciphergram is a (short) message that has been transformed by a so-called simple substitution cipher. The well known Caesar shift is one of these, wherein the ciphertext is made from the plaintext by substituting for each letter the one three places to the right in the alphabet, modulo 26: A becomes D, Y becomes B, M becomes P, and so on.
The Ciphergram Solution Assistant makes these assumptions about the cipher:
No cipher letter may stand for itself in the plaintext. (But see below, about Enforce the Rule.) Each cipher letter stands for a unique plaintext letter, and each plaintext letter stands for a unique cipher letter (1:1 mapping). The spacing and punctuation of the plaintext is preserved. The plaintext is spelled correctly throughout.
To try a problem of your own, delete the contents of the form. Then, enter the enciphered message, enter the enciphered attribution, and click Solve. Please read the Help pages if you have trouble with this.
The Ciphergram Solution Assistant will do the best it can to solve the ciphergram. It usually comes close to the intended answer, with at most a few wrong letters.
You should leave the Initial Key box empty at first. Please read the Hints page for more about the Initial Key box.
Enforce the Rule button: Unless you are sure you want to relax the rule that requires cipher characters not to stand for themselves in plaintext, you should leave the Enforce the Rule button checked. The CryptoQuote puzzles in the newspapers obey the rule.
