Chef on RHEL8 or RHEL9 servers

Hi All,

We are using Chef for automation in our on-prem environment, currently the chef is running on a RHEL7 server but we are planning to do an OS upgrade to RHEL8 or RHEL9. We are using below versions of chef and need to know whether these are SHA1 or SHA256 signed, can anyone suggest how to check it?

chef-server-core-12.17.33-1.el7.x86_64
chef-manage-2.5.16-1.el7.x86_64
chef-14.13.11-1.el7.x86_64

As for RHEL8 or RHEL9 servers these packages has to be SHA256 signed so kindly suggest which version would be compatible.
