如何看navicat数据库连接的密码_查看navicat连接数据库的密码
一、版本问题
场景:在配置数据库连接后,忘记了数据库的密码,想要找回来。
其实有些版本(好像是低版本才有,具体哪个版本就没去研究了)在配置连接页面,是有个选项勾选是否显示密码的,有的话就简单了。
这里主要是介绍不能直接显示密码的版本,忘记密码后,如何进行查看密码(前提是你之前配置的是正确的!)。
二、不支持直接查看密码的版本,查看密码的步骤
第一步:导出链接,导出连接获取到 connections.ncx 文件
这里需要勾选 导出密码!!! 不然导出的文件里不包含加密的密码
第二步:找到加密密码,进行破解
在导出的connections.ncx文件中找到password,然后复制出来
找个在线执行php的网站(如果你本地有的话,也行),就找了一个:https://www.w3cschool.cn/tryrun/runcode?lang=php,
打开这个网址https://www.w3cschool.cn/tryrun/runcode?lang=php,把下面的代码复制进去,并且把倒数第三行换成你需要解密的密码

如图得到了解析出来的密码,文章来自https://blog.csdn.net/weixin_41287260/article/details/141476859,我害怕原来博主删文章什么的,重新复制一份。
