Caesar Cipher Programming Algorithm in C++. In cryptography, a Caesar cipher, also known as shift cipher, Caesar's cipher, Caesar's code or Caesar shift, is one of the simplest and most widely known encryption techniques. It is a type of substitution cip

TheCaesar Cipher encryption rulecan be expressed mathematically as: c = (x + n) % 26 Where c is the encoded character, x is the actual character, and n is the number of positions we want to shift the character x by. We’re taking mod with 26 because there are 26 letters in the ...
Other, later versions of the Caesar Cipher are more difficult to break. For instance, some versions of the cipher exist where a code word is used to ‘lock’ some letters of the alphabet in place. The other letters shift around these set points, meaning the code word must be known ...
