Score: 6.7/10 (Innovation: 7, Technical: 7, Documentation: 4, Utility: 6)

This project provides a novel approach to air-gapped file encryption by embedding encrypted data and a decryption mechanism within a single self-decrypting HTML page. It leverages reproducible builds and OpenPGP signatures for auditability, allowing decryption without network access using just a web browser or bare openssl. It's interesting for its clever manipulation of HTML structure to maintain signature integrity while enabling decryption.

Target audience: security engineers, backend devs, devops
