Vying for:

Most Socially Useful Hack


We are sneaky people who loves to hide secrets from others ;)

What it does

Secretivity uses zero-width characters in a binary system to encode a secret text behind a normal text that looks absolutely normal and unsuspecting! Includes an option to encrypt/decrypt text with AES-256.

How we built it

Secretivity is built natively with Swift in Xcode.

Challenges we ran into

Many messaging apps tend to truncate whitespace characters. This will remove our secret text when pasting into messaging apps.

Accomplishments that we're proud of

Surviving winter without winter clothes in this hall for 24 hours.

What we learned

Heat from the laptops are not sufficient for warmth.

What's next for BH - Secretivity

Expose an API for encrypting with zero-width characters for use with other purposes. Such as implementing a messenger-based encryption service or pretty much any purpose where security by obfuscation is needed.
