基于C#實現(xiàn)rar文件密碼破解工具
更新時間：2025年07月01日 11:08:51 作者：iCxhust
這篇文章主要為大家詳細(xì)介紹了如何基于C#實現(xiàn)一個rar文件密碼破解工具,文中的示例代碼講解詳細(xì),感興趣的小伙伴可以跟隨小編一起學(xué)習(xí)一下
本文主要介紹了一個C#編寫的RAR壓縮文件密碼恢復(fù)工具,該程序通過加載密碼字典文件,逐個嘗試密碼來破解受密碼保護(hù)的RAR文件。
主要功能包括
1.選擇RAR文件和密碼字典
2.顯示恢復(fù)進(jìn)度
3.統(tǒng)計嘗試密碼數(shù)量和速度
4.計算剩余時間
本工具采用后臺線程運行密碼破解過程,可以避免UI凍結(jié),并提供取消操作功能。
