Comment 1 Brian Stinson 2022-04-01 17:20:29 UTC 
@rharwood It looks like kernel -71 -72 -73 and -74 are signed properly in CentOS Stream, but after that the kernels are signed with the Test cert:

• pesign -l --in=vmlinuz                                      
---------------------------------------------
certificate address is 0x7f1b2bff3808
Content was not encrypted.
Content is detached; signature cannot be verified.
The signer's common name is Red Hat Test Certificate
No signer email address.
Signing time: Wed Mar 30, 2022
There were certs or crls included.
---------------------------------------------


Did this update to pesign cause any changes here? https://kojihub.stream.rdu2.redhat.com/koji/buildinfo?buildID=17784


Kernel -74 (signed properly): https://kojihub.stream.rdu2.redhat.com/koji/buildinfo?buildID=17731
Kernel -75 (signed with the test cert): https://kojihub.stream.rdu2.redhat.com/koji/buildinfo?buildID=17791
