使用 OpenSSL 工具進(jìn)行密碼明文的加密與解密
Written By: Xinyao Tian
簡(jiǎn)介
本文檔描述了使用 OpenSSL 工具在 Bash 腳本中對(duì)密碼進(jìn)行加密和解密的簡(jiǎn)單方式。
BASE64 的加密與解密腳本
使用 Base64 算法進(jìn)行密碼的加密
腳本名稱(chēng)為 encryptPasswd.sh, 腳本內(nèi)容如下:
#!/bin/bash
# Script developed by Xinyao Tian on 2023/08/10
echo "INFO: Encrypting plain text password through $0"
passwd_plaintext=$1
passwd_encrypted=`echo $passwd_plaintext | openssl enc -base64`
echo "INFO: Encrypted password is:"
echo $passwd_encrypted
使用 Base64 算法進(jìn)行密碼的解密
腳本名稱(chēng)為 decryptPasswd.sh, 腳本內(nèi)容如下:
#!/bin/bash
# Script developed by Xinyao Tian on 2023/08/10
echo "INFO: Decrypting encryped password through $0"
passwd_encrypted=$1
passwd_plaintext=`echo $passwd_encrypted | openssl enc -base64 -d`
echo "INFO: Decrypted password is:"
echo $passwd_plaintext
使用方法
檢視目錄中的腳本:
[flinkrt@p0-tkldmp-rc01 ~]$ ls -l
total 8

加密使用方法如下:
[flinkrt@p0-tkldmp-rc01 ~]$ ./encryptPasswd.sh 123456
INFO: Encrypting plain text password through ./encryptPasswd.sh
INFO: Encrypted password:
MTIzNDU2Cg==
解密使用方法如下:
[flinkrt@p0-tkldmp-rc01 ~]$ ./decryptPasswd.sh MTIzNDU2Cg==
