@prologic@twtxt.net I’m sure you can somehow install something that calculates blake2b on OpenBSD. But it’s not part of the base system as a standalone CLI tool, there only appear to be Perl modules for it. The other SHA tools do exist.

I mean sure if i want to run it over on my tooth brush why not use something that is accessible everywhere like md5? crc32? It was chosen a long while back and the only benefit in changing now is “i cant find an implementation for x” when the down side is it breaks all existing threads. so…

here are plenty of implementations https://www.blake2.net/#su

@movq@www.uninformativ.de i’m sorry if I sound too contrarian. I’m not a fan of using an obscure hash as well. The problem is that of future and backward compatibility. If we change to sha256 or another we don’t just need to support sha256. But need to now support both sha256 AND blake2b. Or we devide the community. Users of some clients will still use the old algorithm and get left behind.

Really we should all think hard about how changes will break things and if those breakages are acceptable.
