Cryptography

Cryptography, or cryptology is the practice and study of techniques for secure communication in the presence of adversarial behavior. More generally, cryptography is about constructing and analyzing protocols that prevent third parties or the public from reading private messages.

While you certainly wouldnt want to use it in todays modern world, a long time ago it might have done the trick. Play Around with different text below. Simply enter some text and press either "Decrypt" to decrypt a encrypted message or "Encrypt" to encrypt a message. Have Fun!
