From f3a2ba44e93e2c192a872f2705fe66dbf39708d6 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Fri, 5 Nov 2021 12:59:55 +0900 Subject: certs: check-in the default x509 config file When x509.genkey is created, it prints a log: Generating X.509 key generation config ..., which is not the ordinary Kbuild log style. Check-in the default config as certs/default_x509.genkey to make it readable, and copy it to certs/x509.genkey if it is not present. The log is shown in the Kbuild style.
