What you are about to enter is what is called a Distinguished Name or a DN. There are quite a few fields but you can leave some blank For some fields there will be a default value, If you enter '.', the field will be left blank. ----- Country Name (2 letter code) [AU]: JP # country State or Province Name (full name) [Some-State]: Hiroshima # State Locality Name (eg, city) []: Hiroshima # city Organization Name (eg, company) [Internet Widgits Pty Ltd]: Server World # company Organizational Unit Name (eg, section) []: IT Solution # department Common Name (eg, YOUR name) []: www.srv.world # server's FQDN
