WebDec 5, 2016 · Well, because we use modular addition you can simply do the following: c = p + k ( mod 26) = p + k − n × 26 ( mod 26). In other words, you can subtract 26 as many times as you want until you get in the index range 0..25 again. In the example above, using a key of 29 is identical to a key valued 29 − 26 = 3. WebApr 10, 2024 · When plain text is encrypted it becomes unreadable and is known as ciphertext. In a Substitution cipher, any character of plain text from the given fixed set of characters is substituted by some other character from the same set depending on a key. For example with a shift of 1, A would be replaced by B, B would become C, and so on.
