Stegnography is the science of hiding messages in plain sight.
What it does
Embeds/extracts messages in text as zero width Unicode characters. This allows implanting secret messages and data in any text application, such as chat, email, and documents.
How we built it
Challenges we ran into
We encountered a clipboard restriction in X11, a windowing environment for Linux. It culls zero width characters past 10 consecutive occurrences, which forced us to manage the distribution of the message throughout the decoy text.
Accomplishments that we're proud of
We made a truly useful program that will see much use outside of the hackathon.
What we learned
Python GUI with TKinter, bitwise operations, and converting between Unicode and bytecode.
What's next for InvisiCrypt
Time to take over the world! (Of casual cryptography.)
