From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

OpenSSH's ssh-keygen command just got a great upgrade.

New video from @vkc@mspsocial.net


Edit:

She has a peertube channel: !veronicaexplains@tinkerbetter.tube and it federatess as a Lemmy Community

The Peertube video in Lemmy.ml: https://lemmy.ml/post/8842820

YouTube thumbnails are cancer

YouTube titles, too :(

DeArrow by the same developer as SponsorBlock seems to be actively developed and community contributions are fast.

TL;DR: It'll use a new, more secure key type.

tl;dw - ed25519 keys are now the default

[–] SteveTech@programming.dev 2 points 11 months ago

Woah peertube federating with lemmy is actually really cool!

Isn't elliptic curves cryptography sensitive to quantum computers attack? Shor's algorithm etc

[–] duncesplayed@lemmy.one 1 points 11 months ago

Yes, it is. ed25519 depends upon discrete log for its security, which Shor's algorithm can (theoretically, of course, not like it's ever been done) efficiently solve.

The post-quantum algorithms are in active research right now. I don't blame anyone for avoiding those at least until we've quantum computers big enough to solve baby toy elliptic curves.

i don't think I've created an RSA key since 2017

[–] aard@kyu.de 1 points 11 months ago (1 children)

A surprising amount of services (including Azure last I tried) can only handle RSA keys, so after trying ecdsa only for a while I ended up adding a RSA key again.

With that said - it's 2023, in almost all cases you should have your keys in a hardware module nowadays, in which case you'd use a different command for keygeneration.

Do you have a link for storing keys in hardware? I have no idea how you'd do that.

I had to create one this year after discovering that connectbot (ssh client on Android) didn't support agent forwarding otherwise.

[–] lemann@lemmy.one 0 points 11 months ago (2 children)

Probably a good idea to look for a different client, call me tinfoil but I wouldn't want to touch a very old mechanism that is supported/pushed by a very recognisable 3 letter agency

[–] 018118055@sopuli.xyz 1 points 11 months ago

Probably. It's in f-droid but increasingly looking not quite unmaintained, but not developed actively enough.

I've just started using SSH inside of Termux, got tired of all the weird pitfalls SSH Clients for Android usually have
