Show HN: Air-gapped file encryption as self-decrypting HTML page

A developer has created an open-source project that allows for air-gapped file encryption using a single, self-decrypting HTML page. The project, which is hosted on GitHub, uses a combination of reproducible builds and OpenPGP signatures to ensure the file's integrity and authenticity. The encryption process is made possible by cleverly manipulating the HTML structure to decrypt the file without breaking the PGP signature, allowing it to be decrypted using only a web browser or the OpenSSL command-line tool. The project's source code is freely available, making it fully auditable.
