16进制数用base64编码批处理版

lockmove

这东西用处就是把md5值再用base64编码.不过我就写了点核心,如果要具体的话,自己添加.
用法是:输入6位16进制的数.输出4位base64.

1. @echo off&setlocal ENABLEDELAYEDEXPANSION
   
2. set code=ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/=
   
3. set /p num=input:
   
4. set num1=%num:~0,2%
   
5. set num2=%num:~2,2%
   
6. set num3=%num:~4,2%
   
7. set /a num1=0x%num1%
   
8. set /a num2=0x%num2%
   
9. set /a num3=0x%num3%
   
10. set /a "T1=(%num1%&252)>>2"
    
11. set /a "T2=((%num1%&3)<<4)+((%num2%&240)>>4)"
    
12. set /a "T3=((%num2%&15)<<2)+((%num3%&192)>>6)"
    
13. set /a "T4=(%num3%&63)"
    
14. echo code:!code:~%T1%,1!,!code:~%T2%,1!,!code:~%T3%,1!,!code:~%T4%,1!
    
15. pause>nul
