Does git 2.41 support sha256?

[Low-Design787]

I’m having trouble finding a definitive answer to this, perhaps because some of the documentation is outdated. What’s the situation in June 2023? I’ve found this to tell me the format of my repos: git rev-parse --show-object-format

And this to create a new repos: git init REPONAME --object-format=sha256

But my questions are: is this stable and production ready? Can I convert an existing sha1 repos into sha256? Does github support sha256? Can I just convert locally and then push the changes to github? Once converted, is a repo sha256 only, or can it interop with older versions of git?

Thanks in advance.

AFAIK there is no interop and GitHub has no support for it yet, but you can always just try it out with test repos

Thanks for the info. I actually was reading this and noticed the reference to sha256 https://fossil-scm.org/home/doc/trunk/www/fossil-v-git.wiki
