Cryptography in RHEL8

RHEL8 has a new mechnism to centralise the cryptographic defaults for a machine.
This is handled by the crypto-policies package. Details of the rationale and update policy can be found in other documents

Strong crypto defaults in RHEL-8 and deprecations of weak crypto algorithms

System-wide crypto policies in RHEL 8
