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

Actually it is the same story with TLS 1.3 and TLS 1.2. A bunch of sites still doesn't support TLS 1.3 (e. g. arstechnica.com, startpage.com) and some of them only support TLS 1.2 with RSA (e. g. startpage.com).

You can try this yourself in Firefox by disabling ciphers (search for security.ssl3 in about:config) or by setting the minimum TLS version to 1.3 (security.tls.version.min = 4 in about:config).

Strange enough TLS 1.3 still doesn't support signed ed25519 certificates :| P‐256, NIST P‐384 or NIST P‐521 curves are known to be "backdoored" or having deliberately chosen mathematical weakness. I'm not an expert and just a noob security/selfhoster enthusiast but I don't want to depend on curves made by NSA or other spy agencies !

I also wondering if the EU isn't going to implement something similar with all their new spying laws currently discussed...

AFAIK, they're not known to be backdoored, only suspected

[–] deepdive@lemmy.world 2 points 11 months ago

Yeah wrong wording, but the fact that we have to depend mostly on NSA's cryptographic schemes makes it very suspicious !
