This is not the flex you think it is, Microsoft.

@Rob_Gustof @enteio @KeePassXC That’s right — it runs entirely in your browser. Once the web app is loaded, you can go offline. It’s completely safe and private. I’m also planning to release a standalone desktop version on the Microsoft Store soon.

[Stefan Oltmann 📯 @StefanOltmann]

@TallNupinks @enteio @KeePassXC Thank you! Sure, I’ll add an encryption feature. 🙂

Nope, the contents can only be extracted using steganography tools. The data is hidden within the image pixels using the LSB (Least Significant Bit) method — a text editor won’t be able to show it.

@enteio @KeePassXC Just found secret.png inside — you totally got me! 😂 Well played! 👌

Thanks a ton for the shoutout and for sharing my tool — really appreciate it! 🙏🏻🙂🍻

🚀 PixelSafe – by Stefan from our Discord community

This #opensource tool lets you hide secrets inside PNG files 🫣

For example, store your @KeePassXC database inside a screenshot, or send private messages to your friends.

Started a new project: PixelSafe, a steganogrphy tool to hide data in PNG pixels. Made with Kotlin/WASM.

I'm excited to introduce my latest side project!

I've been exploring Compose for Web and experimenting with Ktor's new WASM support, which led me to create a seed browser for my favorite game Oxygen Not Included.

See https://t.co/2nHfhPOUgd :)

@IgnatBeresnev Thanks for checking. Accidentally I released said version some time ago, but folks at Maven Central deleted it for me. Looks like it’s not completely deleted.
