如何查看navicat已连接用户的密码
2024-10-21 10:17:26
1：从注册表中查看加密后的密码。
1.1：windows键+r，输入 regedit
1.2：在注册表中找到 \HKEY_CURRENT_USER\SOFTWARE\PremiumSoft\navicat\servers 并找到 UserName 即 账号
1.3：从上面步骤中，打开注册表、并找到如下图片中的密码栏：Pwd（加密的密码）
2：解密密码，打开在线工具运行一下代码，并修改倒数第二行代码，将上面的密码写入decrypt(’’);中，点击运行。即可
2.1：在线编码网址，https://tool.lu/coderunner/
2.2：解密代码：
