Navicat查看数据库的密码
Navicat查看数据库的密码前⾔
现在数据库密码都是⾃动保存的，时间⼀长就会忘记某⼀个数据库的密码
但是Navicat保存的数据库密码⼜是加密的，这时候就需要破解来获取密码
整理内容来⾃
⼀、⾸先打开注册表，到navicat中对应的数据库加密密码
使⽤win+R键打开命令⾏，输⼊ regedit进⼊注册表
到图⽚中对应⽬录下数据库的PWD，打开并复制加密密码
⼆、然后去在线⼯具运⾏php代码破解加密内容获取密码
打开梦见天崩地裂
复制最下边的代码到在线⼯具页⾯中
根据⾃⼰使⽤的navicat版本选择对应的版本号，修改decrypt('A3E590714589C4E9F7')；中的内容为刚
才复制的字符串运⾏获得密码【如果选择12版本不对，可以尝试11，我个⼈navicat版本是12，但是使⽤版本号为11才能破解成功】<?php
