It's really just focused on a keto diet, but using the app at https://www.carbmanager.com you can look up low-carb foods really well and enter units in all kinds of ways. I know someone who successfully used it for about 2 months a while ago, but then they went off keto and the app DB didn't have many non-carb heavy foods.
> Are you indicating that Cloudflare's implementation isn't truly fully post quantum secure because of lagging certificate standards/technology?
Yes, although I wouldn't say "truly" because they haven't intimated that it is. I'm not claiming any malfeasance on Cloudflare's part: they have been very explicit about the fact that the PQ components deployed so far are only in the key exchange. Bas Westerbaan has a great post on the Cloudflare blog about the state of PQ in 2024.
Hmmm. This solution still leaves quite a few days a compromised certificate can be used(!).. that's significant.. but I guess it's better than nothing?
I have been using Syncthing fork since before the official app was discontinued, and can vouch for its quality. My favorite feature is that it allows conditional pausing of folders based on phone state, such as if the phone is charging or connected to WiFi. Just be warned that the version on Google Play was no longer updated last time I checked (Googles fault), so you're better downloading releases from the Github repo.
What is addressed recently by NIST, Cloudflare, Google, Apple, and others primarily involves potential(?) weaknesses in TLS key exchange & asymmetric cryptography. Let's Encrypt is more about certificates, I think, no?
The cert gives assurance the right endpoint has been reached to bootstrap tls. So arguably its part of the attack surface. The tls key exchange may not have direct dependency but it has some indirect? Clearly the on the wire pki used to establish emphemeral session keys would be the main issue and that is down to the webserver and browser not letsencrypt.
