In cryptography, a Caesar cipher, also known as Caesar's cipher, the shift cipher, Caesar's code, or Caesar shift, is one of the simplest and most widely known encryption techniques. It is a type of substitution cipher in which each letter in the plaintext is replaced by a letter some fixed number of positions down the alphabet .
The trifid cipher is a classical cipher invented by Félix Delastelle and described in 1902. [1] Extending the principles of Delastelle's earlier bifid cipher, it combines the techniques of fractionation and transposition to achieve a certain amount of confusion and diffusion: each letter of the ciphertext depends on three letters of the plaintext and up to three letters of the key.
At the end of every season 1 episode of the cartoon series Gravity Falls, during the credit roll, there is one of three simple substitution ciphers: A -3 Caesar cipher (hinted by "3 letters back" at the end of the opening sequence), an Atbash cipher, or a letter-to-number simple substitution cipher. The season 1 finale encodes a message with ...
THE GENERAL GOES BACK ON WEDNESDAY. RESTINGE YOUR SERVANT TO COMMAND. The third letter after each punctuation reveals "Panel at East end of Chapel slides". A dot or pinprick null cipher is a common classical encryption method in which dot or pinprick is placed above or below certain letters in a piece of writing. [4]
A three-letter word—the most complicated, multifaceted word in the English language. Don’t even get us started on these words that mean the exact opposite of what you think .
Cryptograms based on substitution ciphers can often be solved by frequency analysis and by recognizing letter patterns in words, such as one-letter words, which, in English, can only be "i" or "a" (and sometimes "o"). Double letters, apostrophes, and the fact that no letter can substitute for itself in the cipher also offer clues to the solution.
