Crypto Img - Encrypt images using other images as the key

Crypto Img is a desktop app that encrypts images by distributing their encrypted data across other images, turning folders into a visual key. Unlike traditional password-only encryption, decryption requires the exact base image set used during encoding. It supports single and batch processing, secure container export (.scx), AES encryption, device-bound licensing, and a limited demo mode. Built for creators who want visual-style protection with real cryptographic strength.

Hey Product Hunt 👋 Crypto Img was born from a simple curiosity: what if encryption wasn’t just about a password, but about an environment? Most tools protect files with a key. I wanted to experiment with something more… physical. In Crypto Img, encrypted image data is fragmented and distributed across a real folder of images. That folder becomes part of the “key”. Without the exact visual set used during encoding, the file is useless. It’s not security by obscurity. Under the hood there’s real AES encryption. But on top of that, there’s a visual layer that makes the structure itself part of the protection. As a solo developer, the biggest challenge was balancing strength and usability. I didn’t want a CLI-only crypto toy. I wanted something creators, designers, and privacy-minded people could actually use. So I built: • A secure container format (.scx) • Single and batch processing • Real cryptographic encryption • A device-bound license system • A demo edition with daily limits It’s a lightweight desktop app focused on control, privacy, and experimentation with visual cryptography concepts. I’d genuinely love feedback, especially from builders and security-curious folks. How would you use something like this?
