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

Air-gapped file encryption packed into a single, self-decrypting HTML page. Repo: https://github.com/ApelegHQ/ts-cms-ep-sfx I was inspired by self-extracting archives. I wanted to share files with basically no dependencies. The goal was: 1. Something that didn't require any installation (assuming a web browser) 2. Have a single file with no network that could self-decrypt 3. Be fully auditable The second point is done by having (sort of(*)) reproducible builds and embedded OpenPGP signatures. The first point is made by cleverly manipulating the HTML structure so that it can decrypt without breaking the PGP signature. It can even decrypt using bare openssl (which was a design goal too, though getting the exact structure right took some work and bug reports). The third point is accomplished by the first two, and by the source being f

Most of my time goes to Group Income (https://groupincome.org) / Shelter (https://shelterprotocol.net), a protocol and platform for building rich decentralised rich (web) applications with end-to-end-encryption. The idea is building the tech for an experience rivaling or surpassing that of siloed apps but with a focus on user and data autonomy. The rest of my time goes into a few personal projects, most with no public URL yet. * An IndieAuth provider based on WebAuthn, the idea being that instead of relying on delegating authentication, it could be handled directly using, e.g., U2F keys or a device. * A temporary e-mail address provider with deterministic addresses for attribution. * A self-service menu / ordering service * An E2EE document signing solution Some of these have led to a few mini-projects that I actively maintain du

e to not finding a fitting solution, such as: * An HTTP media type negotiator (https://github.com/ApelegHQ/ts-http-media-type-negotiator) -- negotiate based on accept headers. This was because I couldn't find a negotiator that correctly parsed headers. * A JS sandbox (https://github.com/ApelegHQ/lot) -- Tried to implement something lightweight yet functional * A MIME multipart encoder and decoder (https://github.com/ApelegHQ/ts-multipart-parser) -- Attempt at a lightweight, general and spec-correct parser * A lightweight ASN.1 DER encoder (https://github.com/ApelegHQ/ts-asn1-der), meant to be used with its sister project (https://github.com/ApelegHQ/ts-cms-classes) --- Part of the document signing project In addition, trying to move a side-side project to Svelte 5: * A web-based self-contained encryption/decryption tool (https://github.com/ApelegHQ/ts-cms-ep-sfx) --- Created to easily share files with maximum compatibility (ZIP archive inside a CMS payload) and minimum requirements.
