[root@monitor ssl.crt]# openssl x509 -in

mail.bob.com.crt -serial -noout

serial=00

[root@monitor ssl.crt]#

不过真实的证书序列号是很长的。

[root@monitor ssl.crt]# openssl x509 -in

my.crt -serial

-noout

serial=D01E40900000274B0000000100000004

[root@monitor

ssl.crt]#

上面是一个真实的证书的序列号，证书的内容如下 (来自

/usr/share/ssl/certs/ca-bundle.crt)
