Sigil is an app that aims to provide multi-layered text encryption for Android with a modern Material 3 interface. I intend to convert it into a complete privacy and cryptography suite until the initial v1.0.0 stable release (Current release: v0.5.0-dev3)
Just implemented the zero-width text steganography section; it was a pain to optimize and to get work across platforms, but I did it in the end. Attached are screenshots of it. I tried to get it to look like the main tab, but I don’t think it worked out quite as well, or it could be that I have looked at the main tab for too long. Anyway, next on the agenda is the whitespace section, also just to be clear, the zero-width one, though not visible, takes a shit ton of characters as it essentially encodes all the data in binary, so even though it isn’t visible, it’s still there and easy to find out. I have thought of making the LLM section specifically to combat it. Stay tuned to find out how well it works (I probably won’t survive implementing the LLM section, but oh well, problem for future me, I guess….)
