shell脚本简单密码加密

1. #!/bin/sh
2. #输入密码
3. echo "请输入原密码："
4. read resultFirst
5. firstPWD=$resultFirst
6. echo "请再次输入原密码："
7. read resultSecond
8. secondPWD=$resultSecond
9. result=""
10. output=""
11. function encryptPWD() {
12. for ((i=0;i<${#firstPWD};i++));do
13. #获取输入每一个字符并转换为ASCII码
14. letter=`printf "%d" "'${firstPWD:$i:1}"`
15. let letter=letter+300
16. result+=$letter
17. done
18. #判断ASCII码长度
19. if [ ${#result} -lt 10 ];then
20. output=${result}
21. echo "您的密码太简单，建议加深密码难度！！！"
22. else
23. output=${result:(${#result}-10):${#result}}${result:0:(${#result}-10)}
24. fi
25. }
26. if [ "$firstPWD" = "$secondPWD" ];then
27. encryptPWD
28. echo "您的加密后密码为："
29. echo $output
30. else
