怎么查看Navicat已連接保存的數據庫密碼?下面本篇文章給大家介紹一下查看navicat已保存密碼的方法,希望對大家有所幫助!
在使用Navicat 是都是習慣性的保存了密碼,久而久之后 就會忘記數據庫密碼, 這就很不舒服了,
但是,這有個技巧,可以查看navicat 已連接保存的密碼
首先去 導出連接
導出連接獲取到 connections.ncx 文件
這里記著 導出密碼!!! 不然導出的文件里不包含加密的密碼
然后找到 文件里 password 字段的值
把他復制出來
開始破譯密碼
多虧一位Github上的大佬寫了個程序;可以直接破解這個加密密碼
程序是php的;如果本地沒裝php也沒關系 , 直接找個在線運行的工具 https://tool.lu/coderunner/
把代碼粘上去就行了
然后把剛復制的 加密密碼 替換倒數第二行 里的值 , 然后運行就行了
$decode = $navicatPassword->decrypt('999239DEBFA1960BCCB12566F1F417A6');
