I feel like I’m missing something here…
Who’s going to be fingerprinting DHCP messages on your home network?
Outside of that, fingerprinting or tracking any DHCP info would be the least of my concerns. You have 0 control over any data the moment your devices connect to a public network. What use is DHCP info when you can person-in-the middle all the traffic anyway?
And anyway, what info are you concerned about? Having had a VERY quick browse of RFC2131 the worst thing would be “leaking” the device MAC address which can be discovered via several other means anyway
Take it as a ranty blog interspaced with some furry art.
You can just ignore the furry art if it’s not your style because helpfully all of the important content is in the text.
Soatok links to the same Latacora blog on the first line and says that they’re only really going to reword what’s said there.
PGP/GPG maintainers have had many years to fix the problems that have been identified but they haven’t. Is it safe when used “properly”? Yes! It’s absolutely safe when used properly but the problem is it’s hard to use full stop.
I’m not saying modern solutions are perfect, because they’re not but the alternates that Latacora ( and Soatok ) suggest are better. Do you want to encrypt a file? Use age. Use minisign/signify for signing. They do do one thing and do it well. Signal is easy to use and sorts all of the key management for you. Most people don’t know what a private key is. They just know they want encrypted messaging because of the NSA or Snowden or whatever his name was on the news, they can’t remember and they don’t really care.
PGP has legitimate use cases but the vast majority of people don’t have those cases and should just use Signal. Signal and the Signal protocol is the centralised tool you’re looking for.
