当我使用 Request.ServerVariables("CERT_SUBJECT") 时,值 C=US 是什么意思?

When I use Request.ServerVariables("CERT_SUBJECT"), what does the value C=US mean?

当我使用 Request.ServerVariables("CERT_SUBJECT") 时,我最终得到这样的字符串:

C=US, O=XXX, OU=XXX, OU=XXX, OU=XXX, CN=DOE.JOHN.JACOB.9999999

值 C=US 是什么意思?这是持卡人的国籍吗?发卡国家?

感谢您的帮助

Request.ServerVariables("CERT_SUBJECT") 给你:

Subject field of the client certificate.

参见 Server Variables

C根据here指定CountryName

An X.509 certificate consists of a number of fields. The Subject field is the one of most relevance to this tutorial. It gives the DName of the client to which the certificate belongs. A DName is a unique name given to an X.500 directory object. It consists of a number of attribute-value pairs called Relative Distinguished Names (RDNs). Some of the most common RDNs and their explanations are as follows:

CN: CommonName
OU: OrganizationalUnit
O: Organization
L: Locality
S: StateOrProvinceName
C: CountryName
