Jornada (Catalan for "Day") is a simple app that can encrypt and decrypt blocks of text. You can use this application in order to keep prying eyes from reading text messages, emails, and other communications.
The main feature of Jornada is that the app creates a new cipher daily. What this means is that at 12:00 AM, your message can no longer be decoded!
Note: This application was created as a homework assignment/proof-of-concept. It is NOT meant to be completely secure, and ANY other Jornada user can decode and read your messages. That said, the cipher is pretty difficult to crack for an average person.
