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.

In 2005, Curve25519 was first released by Daniel J. Bernstein.[5] (https://en.wikipedia.org/wiki/Curve25519)

DJB? Nice! Always been a fan.

Yeah, look at the curves on that guy.

It says that

Starting in 2014, OpenSSH defaults to Curve25519-based ECDH.

So what changed recently? (I didn't watch the video, in fairness).

ssh-keygen now defaults to ed25519 so you don't have to do ssh-keygen -t ed25519 anymore. The default since 2014 is for key exchange when connecting.

Got it, thank you!
