在线运行此php解密navicat导出的密码！

解决问题：

我们经常使用navicat连接数据库，有时候时间久了之后，会忘记之前的密码，那么现在我们有办法获得只要正常连接的数据库的密码

步骤：

1.导出连接

a.选择想要获取密码的数据库即可

b.拿到保存到本地的connections.ncx文件中的Password

2.解密password

a.登陆https://tool.lu/coderunner，使用PHP在线运行工具

b.粘贴如下代码

在 文件>导出链接>可以看到加密处理过的password=‘xxx’
可以放在解析工具中解析出来，已经有做好的小工具了
我搜索的时候整理了另一种放法： 用php解密
然后百度 在线运行php 在php在线运行网站运行下列代码
我在网上找的版本都是两个文件还不好运行，
我把找到的两段代码沾到一起了，可以方便直接用
11如果不行试一下12，decrypt(‘E75BF077AB8BAA3AC2D5’)替换单引号里的内容
