For example, in the Caesar Cipher we saw how each letter in the alphabet was mapped to a different letter. For example, A→D, B→E, and C→F, when we're using a shift of four. This kind of cipher is known as a shift cipher. Review how this works using the interactive tool below: In this case, we don’t need a codebook.

WebA well-known example of a substitution cipher is the Caesar cipher. To encrypt a message with the Caesar cipher, each letter of message is replaced by the letter three positions later in the alphabet. Hence, A is replaced by D, B by E, C by F, etc. Finally, X, Y and Z are replaced by A, B and C respectively. WebHowever, in cryptography, code has a more specific meaning: the replacement of a unit of plaintext (i.e., a meaningful word or phrase) with a code word (for example, "wallaby" replaces "attack at dawn"). A cypher, in contrast, is a scheme for changing or substituting an element below such a level (a letter, a syllable, or a pair of letters, etc ...
