Additional info WRT to FIPS 140-3

OpenSSL FIPS can be compiled from source on Raspberry Pi Systems, however an
Important distinction:

OpenSSL 3 FIPS support is provider-based:
enable-fips
fips.so / fips.dll
openssl fipsinstall
fipsmodule.cnf

Distro/kernel FIPS mode is system-level:
boot-time policy
kernel/userland enforcement
distro packages and validation hooks
So:
V-270744 - Ubuntu 24.04 LTS must implement NIST FIPS-validated cryptography
check text /proc/sys/crypto/fips_enabled is an example of a distro/kernel-level FIPS indicator
but it is not what this OpenSSL/Pi OS Trixie repo is using.

The OpenSSL/Pi OS Trixie repo is using a provider model, not a Linux sysctl check
If using Ubuntu 24.04 for this project the FIPs module is only availabel in the Pro version ($) and not compatible with Raspberry Pi
The Ubuntu Server package for Raspberry Pi is an additional 2/3 larger than the Pi OS Lite Package.

The Debian unstable branch has OpenSSL Kernel mode which could be applied to Pi OS but I am uncertain of its success.

So, to reiterate, for this current phase of the project FIPS is not worth the $ or time for a training exersize.
