Announcing 'Flip'

Flip is a handy tool for inverting a file. 0's flip to 1's, 1's flip to 0's.

1. Step one: Upload an original file, such as myreport.doc.
2. Step two: Save the flip file myreport.doc.flip.
3. Repeat with the .flip file and the original file is restored.

How is Flip useful? If .exe downloads are blocked, you can create a .exe.flip file on another computer, email it to yourself, and use Flip to restore it to a normal .exe file. This method bypasses exe filters by 1) changing the file extension and 2) scrambling the contents of the file.

Source code exists for a CLI version. Run make.
