I don't think that is correct. The RHEL 8 openssl which was FIPS 140-2
validated is 1.1.1k. See:
https://csrc.nist.gov/CSRC/media/projects/cryptographic-module-validation-program/documents/security-policies/140sp4642.pdf
Does RHEL publish the source of their fork somewhere? In OpenSSL 1.1.1 the
code for FIPS_mode is:
int FIPS_mode(void)
{
/* This version of the library does not support FIPS mode. */
return 0;
}
Do you know if RHEL patched OpenSSL to allow FIPS_mode() to return other than 0
or if that function is useless regardless?
Yes the RHEL and OpenSUSE rpms for openssl are heavily patched for the
FIPS versions, as is the Ubuntu one. It has been a while but last time I
looked at all of this they were all using very similar patches to allow
the "system wide" FIPS mode rather than depending on the app to
explicitly go into FIPS_mode().
I can look for links, but investigating it involved (for example)
installing the source rpm and then wading through hundreds of patches in
the SOURCE directory.
