オレオレ証明書を一撃で作るワンライナー

Posted at

なんかテストとかでオレオレ証明書がたくさん欲しいとき、いちいちインタラクティブに作成するのは面倒。

sudo openssl req -batch -new -x509 -newkey rsa:2048 -nodes -sha256 \
  -subj /CN=example.com/O=oreore -days 3650 \
  -keyout /etc/httpd/ssl.key/example.key \
  -out /etc/httpd/ssl.crt/example.crt

こんな感じでたくさん作れます。

for x in {0..9}; do
  sudo openssl req -batch -new -x509 -newkey rsa:2048 -nodes -sha256 \
    -subj /CN=$x.example.com/O=oreore -days 3650 \
    -keyout /etc/httpd/ssl.key/$x.key \
    -out /etc/httpd/ssl.crt/$x.crt
done
