Sorry, I meant to include the config information in my previous email. I should probably go back to the beginning, I've been trying a lot of different combinations without success, so unwinding to the beginning and taking one step at a time is probably appropriate.
Since I want the FIPS changes limited to my application only, this is based on the response from Dr. Paul Dale earlier in the thread, the first approach he recommended, so the application code looks like this:</div>

<div> </div>

Since I'm back to not using my own config file, this is the relevant content in /usr/local/ssl/openssl.cnf. Again, from Dr. Paul Dale's advice of needing a FIPS section, and not needing base or default sections:</div>

What is in the /usr/local/ssl/openssl-fips.cnf config file?<br>
<br>
Does the config file attempt to activate the FIPS provider itself? Does <br>
it supply the necessary FIPS provider config parameters?<br>
<br>
Typically the config file has a ".include" directive in it which <br>
includes the necessary FIPS config params. That included file will look <br>
something like this:<br>
<br>
$ cat fipsmodule.cnf<br>
<br>
[fips_sect]<br>
<br>
activate = 1<br>
<br>
conditional-errors = 1<br>
<br>
security-checks = 1<br>
<br>
module-mac = <br>
95:06:06:D1:85:17:92:F6:7B:7D:C2:43:36:A4:59:5D:75:6F:39:E6:13:0B:4B:26:5A:1B:48:78:33:5B:BE:F0<br>
<br>
Most likely what is happening is that the FIPS provider is failing to <br>
load. Either because it cannot find the fips.so file, or because the <br>
necessary FIPS config parameters above are not found or not correct.<br>
<br>
You can test whether a provider is actually available for use or not <br>
using the OSSL_PROVIDER_available() function call. E.g.:<br>
<br>
if (!OSSL_PROVIDER_available(fips_libctx, "fips")) {<br>
/* error handling */<br>
}<br>
<br>
<a href="https://www.openssl.org/docs/man3.0/man3/OSSL_PROVIDER_available.html">https://www.openssl.org/docs/man3.0/man3/OSSL_PROVIDER_available.html</a><br>
<br>
If things are failing then you might find it helpful to dump the OpenSSL <br>
error stack to try and get some clues as to what the problem might be, e.g.<br>
<br>
ERR_print_errors_fp(stdout);<br>
<br>
<a href="https://www.openssl.org/docs/man3.0/man3/ERR_print_errors_fp.html">https://www.openssl.org/docs/man3.0/man3/ERR_print_errors_fp.html</a><br>
