 To generate a private key and certificate, you may use the `openssl` commandline utility:
 
-    openssl req -newkey rsa:2048 -new -x509 -days 3652 -nodes -out sp.example.org.crt -keyout sp.example.org.pem
+    openssl req -newkey rsa:3072 -new -x509 -days 3652 -nodes -out sp.example.org.crt -keyout sp.example.org.pem
