About this app

Encrypt messages with a substitution cipher made famous by Julius Caesar. Copy and paste your encrypted messages to friends in other messaging apps or emails. Select an Encode value and the message can only be decoded with the opposite value. For example, a message encoded with a value of 5 can only be decoded by a value of -5.

Messages encoded with value 0 are plaintext.

Have fun!
