Thoughts on web design, security, crypto...

• What is crypto?
• Breach excuse generator
• Light and responsive web design

And yes, I wrote most of this page in nano. Via PuTTY. And it was fun. Mostly. Somewhat. For a moment.

...okay not as much as copy/pasting some ASCII art.

PGP key

Brand new key, hurray. Needs GnuPG 2.5.something because it uses ML-KEM-1024.
I put a short-ish expiration date on it, because probably I’ll have to change it in the not too distant future, since right now it’s half PQC, half not... But it still beats an expired key that I had been unable to use since GnuPG broke support for oversized RSA keys.

Also, hi

I really just set this up in order to give a little something to whomever gets curious enough about my e-mail. Hi, you ^^

Software

Oh, a new section... with not much here yet, but this should grow, given enough time.

• SimtinHTTP, a simple and tiny HTTP server written in Rust. Since it’s hosted by itself (don’t let the Apache header fool you, it’s proxied) and doesn’t support HTTPS (and I haven’t yet gone through the headache-inducing trouble of configuring Let’s Encrypt on that kind of setup), I guess I should provide a couple of SHA256 hashes:
  • simtin-http-0.8.0.exe (Windows x64): 99c3ec93eeef5f471cc1379b1f98b0132b782874077e6f2e04f387abc7d4a226
  • simtin-http-0.8.0-musl (Linux): 49c0ea404f044bc0576b2a81ff336bfea33afd46abdb86ed960f6ab71346624e
  I also provide automatic builds here, if you prefer the very latest thing (might be buggy sometimes).
• list-features, a Rust crate that extracts the list of enabled feature flags during compilation. I wrote it because I didn’t find something suitable (small / no deps, low MSRV) for use in SimtinHTTP and other projects.
• fifo-cache, a minimalist, thread-safe, FIFO (First In, First Out) cache with TTL (Time To Live) support for Rust. Same motivation for writing it as for the list-features crate.
• CompanyFlag, a browser add-on (manifest V3) that shows the country of origin of the current website’s company. Here it is for Firefox and for Edge. For the other browsers with MV3 support, it can be installed from source or from the Gitlab pipeline’s artifacts.
