[barbican] Simple Crypto Plugin kek issue
Hi, I have installed barbican and using it with openstack magnum. When I am using the default kek describe in document below, works fine and magnum cluster creation goes successful. https://docs.openstack.org/barbican/latest/install/barbican-backend.html But when I generate a new kek with below command. python3 -c "from cryptography.fernet import Fernet ; key = Fernet.generate_key(); print(key)" and put it in barbican.conf, the magnum cluster failed to create and I see below logs in barbican. 2021-10-29 12:53:28.932 568554 INFO barbican.plugin.crypto.simple_crypto [req-aaac01e9-82af-421b-b85a-ff998d904972 ad702ac807f44c73a32a9b7a795b693c d782069f335041138f0cb141fde9933f -

You should remove old data( project kek) in table kek_data(barbican), and your project kek will issued with your new master kek. Ammad Syed <syedammad83@gmail.com> 于2021年10月29日周五 下午4:04写道：
