Policy "Hardened Amazon Linux 2023 (version 2)" is failing on the latest AL 2023 with the FUTURE crypto policy.

The problem is we made the boxes more secure by usr/bin/update-crypto-policies --set FUTURE which dropped some Ciphers, Group exchange, Key exchange, and MACs and added others.

Maybe a new policy for DEFAULT crypto policy and another for FUTURE?

Love the tool, working out well as we harden our OS.

Just out of curiosity, where did that update-crypto-policies command come from, @Houlistonm ?

Appears to upstream from Amazon ...

You mean these?

That apparently was ported to other distros as well, but is not actively maitnained outside of RHEL.

looks right (from memory), I'm on holiday this week, so I can't compare to one of our VMs.
