A. The Additive (or shift) Cipher System The first type of monoalphabetic substitution cipher we wish to examine is called the additive cipher. In this cipher method, each plaintext letter is replaced by another character whose position in the alphabet is a certain number of units away. We actually shift each letter a certain number of places over. Caesar cipher (shift cipher) is a simple substitution cipher based on a replacement of every single character of the open text with a character, which is fixed number of positions further down the alphabet.In the times of Julius Caesar was used only the shift of 3 characters, but nowadays the term Caesar cipher refers to all variants (shifts) of this cryptosystem.

I'm trying to make a simple Caesar cipher in java that accepts 2 arguments. One being the phrase, and the next being the shift of the letters. I'm very new to Java, and I'm still trying to understand the basics. As a requirement, the cipher should keep capital letters capital, and lower case letters lower case. Java Program on Caesar Cipher. The Caesar cipher, also known as a shift cipher, is one of the simplest forms of encryption. It is a substitution cipher where each letter in the original message (called the plaintext) is replaced with a letter corresponding to a certain number of letters up or down in the alphabet.
