You are about to be asked to enter information that will be incorporated

into your certificate request.

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) [XX]:CN

State or Province Name (full name) []:ShangHai

Locality Name (eg, city) [Default City]:ShangHai

Organization Name (eg, company) [Default Company Ltd]:IT

Organizational Unit Name (eg, section) []:IT

Common Name (eg, your name or your server's hostname) []:example.com

Email Address []:admin@example.com

Certificate is to be certified until Mar 20 14:54:33 2032 GMT (3650 days)

Sign the certificate? [y/n]:y

1 out of 1 certificate requests certified, commit? [y/n]y

Write out database with 1 new entries

The stateOrProvinceName field needed to be the same in the

CA certificate (ShangHai) and the request (ShangHai)

1.CA默认使用policy_match策略，要求请求证书和CA证书 countryName stateOrProvinceName organizationName三个字段保持一致，如果不一致会报错

2.当上面三个字段保持一致时，请求证书和CA证书编码不一致时也会报错，CA编码为utf8only
