openssl常用命令行

Base64编解码

[root@dev ~]# echo -n "chenfy" | openssl base64
Y2hlbmZ5
[root@dev ~]# echo "Y2hlbmZ5" | openssl base64 -d
chenfy[root@dev ~]# 

文件一致性校验

[root@dev ~]# openssl md5 /etc/passwd
MD5(/etc/passwd)= d66feb4f3f36a9e2f9cd8aaa6d8c1d30

[root@dev ~]# openssl sha1 /etc/passwd
SHA1(/etc/passwd)= 2201ea5ac6e340439ace6376e26e71bc3d75759e

对称算法加解密

[root@dev ~]# openssl enc -e -aes-128-cbc -k 1234 </etc/passwd >cipher
[root@dev ~]# openssl enc -d -aes-128-cbc -k 1234 <cipher | diff /etc/passwd -
[root@dev ~]#

[root@dev ~]# openssl enc -e -des-ede3-cbc -a -k 1234 </etc/passwd >cipher
[root@dev ~]# openssl enc -d -des-ede3-cbc -a -k 1234 <cipher | diff /etc/passwd -
