centos下https 证书生成及转换方式
1、生成证书文件:
# mkdir cert # openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout private.key -out public.crt
# ls -ltr
total 10
-rw-r--r-- 1 root root 1220 Mar 23 13:41 public.crt
-rw-r--r-- 1 root root 1704 Mar 23 13:41 private.key
2、将crt证书转换成pem格式:
# openssl x509 -inform PEM -in public.crt > cert.pem [root@localhost cert]# ls -ltr total 15 -rw-r--r-- 1 root root 1220 Mar 23 13:41 public.crt -rw-r--r-- 1 root root 1704 Mar 23 13:41 private.key -rw-r--r-- 1 root root 1220 Mar 23 13:51 cert.pem
3、将key证书转换成pem格式:
# openssl rsa -in private.key -text > key.pem writing RSA key [root@localhost cert]# ll total 15 -rw-r--r-- 1 root root 5681 Mar 23 13:54 key.pem -rw-r--r-- 1 root root 1704 Mar 23 13:41 private.key -rw-r--r-- 1 root root 1220 Mar 23 13:41 public.crt
4、pem证书转换成crt格式:
# openssl x509 -in key.pem -out public.crt
5、pem证书转key格式:
# openssl rsa -in key.pem -out privkey.key
