Ceaser Cipher Java Implementation The Caesar cipher, also known as a shift cipher, … Before looking at the caesar cipher program in java with output for encryption and decryption, first, we need to understand the terms plaintext and ciphertext. 3. Mathematical representation The encryption can be represented using modular arithmetic by first transforming the letters into numbers, according to the scheme, A = 0, B = 1,…, Z = 25. Replies. The system was designed using "Java 2 Micro Edition" language which is the third part of Java language used in mobile applications.
