## What is s?

s-Note allows encrypting note into an image leveraging on mix of steganography and cryptography techniques. The encryption process requires the user to select its own password. Images that contain notes must not be modified: not resized or filtered in order to preserve the integrity of the note itself.

s-Note exploits the standard AES cryptography algorithm to encrypt  user info and a modified version of the F5 steganography algorithm to inject them into an image.
