我使用这个非常好的教程生成了一个自签名证书:

https://www.youtube.com/watch?v=1xtBkukWiek

但是，当我导入证书时，主题(“颁发给”)和颁发者(“颁发者”)属性都在证书存储中显示为设置过程中提供的“通用名称”。如何创建 X509 证书并为 Subject 和 Issuer 指定不同的值？

Answer 1

How can I create an X509 certificate and specify different values for "issued to" and "issued by"?

你不能。自签名意味着颁发者的专有名称与主体的专有名称相同。这也意味着授权 key 标识符 (AKI) 与主题公钥 (SPKI) 相同。

这是来自 CA 根的示例，它也是一个自签名证书。 CA 根证书和自签名最终实体证书之间存在一些差异。例如，CA 设置基本约束的 CA=true和 critical .
