Worth knowing that there is currently an openssl3 issue to "just build it" (it always worked), and it's also impacting Fedora 36 :

https://bugzilla.redhat.com/show_bug.cgi?id=2022033
https://github.com/AGWA/git-crypt/issues/232

Just to test, I gave it a try with a slightly modified version :

And was able to rebuild in copr and did a functional tests on a stream 9 host and was able to unlock a git-crypted repo (with symmetric key, haven't tried with gpg agent)

FWIW, just found that OPENSSL_API_COMPAT option by following upstream issue and https://github.com/loqs/PACKAGES-OSSL3/commit/5d7999584dc0f45fae6489bf579f0622425e47f4

This package has changed maintainer in Fedora. Reassigning to the new maintainer of this component.
