Mad Decent Crypto

Just yesterday my team and I took 3rd place at HackRU for our submission, MAD DECENT CRYPTO. The application performs steganographic encryption on messages it receives through a text message, and sends a decryption key to the recipient specified in the message. The messages are encrypted into pictures of Riff Raff, which we pull from Flickr and then post in a stream. The recipient gets a timestamp along with their key, which they use to find their image in the stream. When they enter their key, the image is decrypted and they receive the message. As soon as the message is decrypted the image is deleted from the server. We used a steganographic PHP class, the Flickr API, and the Twilio API for sending/receiving text messages.
