Webexamples, this will be di cult to do without a formula. An encryption based on a formula of the type c p +a mod 26 (5) is called a shift code because we can think of shifting the alphabet over a spaces to do the coding. Because of this equation, it is also called an additive code or cipher. What makes bob raymer tonasket waWebApr 12, 2024 · Note that steganography and cryptography are not mutually exclusive.
