This command is disabled in Red Hat Enterprise Linux. The FIPS provider is automatically loaded when the system is booted in FIPS mode, or when the environment variable OPENSSL_FORCE_FIPS_MODE is set. See the documentation for more information.
This functionality was added in OpenSSL 3.0.
Red Hat Enterprise Linux uses a supplementary config for FIPS module located in OpenSSL configuration directory and managed by crypto policies. If present, it should have format
[fips_sect] tls1-prf-ems-check = 0 activate = 1
The tls1-prf-ems-check option specifies whether FIPS module will require the presence of extended master secret or not.
The activate option enforces FIPS provider activation.
