  • Is it possible to have FIPS enabled in the RHEL kernel without it affecting apache?
    • If not, what stops apache with mod_ssl from running if FIPS in enabled in the kernel?
  • Does the kernel need to be running with FIPS enabled for tools like authconfig to use the FIPS algorithms like SHA512?
    • What about configuring SSH daemon to access the FIPS algorithms?
