WebDec 22, 2024 · “The Caesar Cipher (Caesar Shift, Caesar’s Code) is a simple, easy to implement substitution cipher. The cipher is named after Julius Caesar. The cipher works by taking the letters of the message and then shifts the letter a defined space along the alphabet. For example a shift of 1 character would make a=b, b=c, c=d etc.” WebNov 5, 2016 · Implementation of Caesar Cipher in C# Step 1 Open your Visual Studio.
