前言

通常在我們測(cè)邏輯漏洞或?qū)懪老x(chóng)的時(shí)候，如果遇到前端加密，我們可以選擇將加密算法拖出來(lái)，對(duì)自己調(diào)試的參數(shù)進(jìn)行加密。

MD5加密實(shí)例

1.登錄測(cè)試，獲取到post參數(shù)

2.在疑似點(diǎn)下斷，并再次發(fā)包

3.查看此處值與加密后的值相同，所以這個(gè)就是加密算法

4.這是一個(gè)閉包函數(shù)，實(shí)現(xiàn)加密算法

~這里可以直接用md5進(jìn)行加密測(cè)試，但不排除他命名為md5()，實(shí)際上自己實(shí)現(xiàn)的加密算法。~
