This is the Caesar Cipher App for Android! You can use it to encrypt or decrypt any message you want with the most famous cipher: the Caesar Cipher.
Named after the roman emperor Julius Caesar, the cipher uses a simple substitution mechanism where each message letter is replaced by another cipher letter. Which cipher letter is used depends on the number of shifts, e.g. a shift of 3 converts an "A" into a "D". When decrypting a ciphertext the shift is reversed so that you end up with the original message.
Try it out for yourself and have fun!
