Picssage lets you hide messages inside pictures. Enter your key word, choose an image, type your message and press Encrypt. After encrypting, the resulting image is about 99% similar to the original one, so nobody will notice the difference. Picssage allows you to encrypt your message in any of the three colour channels of your image, meaning that you can hide up to three diferent messages in a single picture. It uses a double protection system, combining cryptography and steganography. If someone tried to decrypt your message using Picssage, they wouldn't be able to as they would need to know your secret key word.
