Steno.io brings encryption to a next level: on a piece of paper. It uses the Puzzle algorithm to generate a secure relation between two sets of words based on a password. The words in the message are then replaced by their corresponding ones in the other set (a dictionary). By having a ciphertext composed of words, Steno.io is able to hide the message in the massive amount of information that is internet. But its best advantage is when wrote down on a paper, it can evade any electronic surveillance.
Open source application creates more secure and better software, giving back the control of the information to the user. This is why Steno.io is under the BSD license.
