| | | | | I remember seeing a tool many years ago that could hide other files in BMP image files. I was a bit too young to understand how it worked, but I think I understand the trick now: Understand the structure of the file type at the byte level. Find a spot that can hold an arbitrary length of data. Sneak in whatever you want in there. As a proof of concept, I used Go to make Sneak - a program to add or extract a hidden file in a ZIP archive. | |

| | | Why a DAO for Berty? (Part I) TLDR: The Berty protocol will never depend on a Blockchain. We plan to set up a DAO to secure governance of its development team. Berty 's mission is to create a protocol and applications enabling secure p2p communication between people. More simply put, it means that Berty's applications will protect confidential conversations between individuals, including in adverse political situations that might compromise the security or the availability of the internet itself. | ||
