is there a way to read the common name from a .pem file in my shell?

推荐答案

首先，.pem扩展名只引用文件中使用的编码类型。
通用名称是证书的主题或颁发者的功能。

First off, the .pem extension only refers to the type of encoding used in the file. The common name would be a feature of the Subject or Issuer of a certificate.

如果.pem文件包含 x509证书，
这应该做的诀窍：

If the .pem file contains an x509 certificate, this should do the trick:

openssl x509 -in cacert.pem -noout -text

这将转储整个证书。 openssl x509 命令有几个选项来抑制您不想看到的字段。您可以在手册页中的 文本选项

This will dump the whole certificate. The openssl x509 command has several options to suppress the fields you don't want to see. You find those explained in the man page, under TEXT OPTIONS
