These are questions better asked of a FIPS lab since they are the experts and we are not.

I expect that your alternative installation process’s validity will depend on the security policy and what it says needs to be done.  This hasn’t been written yet so there is no answer at this point.

Skipping the self tests is definitely not permitted.  The full suite of self tests *must* be run before the module can be used.

You question prompts the possibility of making fipsinstall a standalone executable, this is something we could look into if we get time.  I expect we’d look favourably on a pull request that allowed either or both options.

To date it was never necessary to ship this utility in our product. Now with OpenSSL 3.0 it appears the only way to get FIPS support is to run "openssl fipsinstall ..." to create a FIPS config file to be included by the main config file. However, at nearly 1MB in size this binary is prohibitively large.

Would I still be considered FIPS compliant if I use my own standalone tool instead of the openssl binary to generate the FIPS config? I presume I don't need to bother with the self-test callback and that it only matters whether or not OSSL_PROVIDER_load(NULL, "fips") succeeds?
