Send secret messages to your friends!
You send a secret message. Only your friend can decode it, with the right password you set and their DecoderPro app!
Type your message into DecoderPro and set a password (if you want). Then, hit "encode message" and decoder pro will "encode" the message. Send them this scrambled text of nonsense, where they will take that text and put it into their DecoderPro app. Using the app (and the right password), they and only they will be able to decode it using DecoderPro and the correct password!
