WebIn 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. WebThis work explores the constructs of music and cryptography to create a consonant harmonic substitution cipher that can hide secret messages. Music notes and the alphabet are both tools for communication. However, can we use music to facilitate the exchange of secret messages? This work explores the constructs of music and cryptography to create … WebThe simple substitution cipher is a cipher that has been in use for many hundreds of years (an excellent history is given in Simon Singhs 'the Code Book').

"In cryptography, a substitution cipher is a method of encrypting in which units of plaintext are replaced with the ciphertext, in a defined manner, with the help of a key; the "units" may be single letters (the most common), pairs of letters, triplets of letters, mixtures of the above, and so forth. The receiver … See more Simple Substitution of single letters separately—simple substitution—can be demonstrated by writing out the alphabet in some order to represent the substitution. This is … See more • Sherlock Holmes breaks a substitution cipher in "The Adventure of the Dancing Men". There, the cipher remained undeciphered for years if not decades; not due to its difficulty, but because no one suspected it to be a code, instead considering it … See more Substitution ciphers as discussed above, especially the older pencil-and-paper hand ciphers, are no longer in serious use.
