FIPS stands for “Federal Information Processing Standards.” It’s a set of government standards that define how certain things are used in the government–for example, encryption algorithms. FIPS defines certain specific encryption methods that can be used, as well as methods for generating encryption keys. It’s published by the National Institute of Standards and Technology, or NIST. FIPS mode is stupid.

For CPUs with the AES New Instructions (AES-NI) support, install the dracut-fips-aesni package as well:
