Yeah, 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 freely available.
Self-decrypting HTML? That's an innovative approach.

(*) Depends on the OS at the moment.
Maybe this is the source?
