What is the ZIP password checker?

The ZIP password checker is a security utility designed to test whether an encrypted ZIP file uses a common weak password. If you want to check whether your own archive password is easy to guess, or you received an encrypted archive that may use a simple numeric code, this utility can provide common password lists and numeric combinations for fast batch testing. Most importantly, everything runs locally in your browser to keep both files and passwords private.

How to batch test ZIP passwords online?

  • Import file:Drag the .zip archive you want to test into the dashed area at the top of the page.
  • Configure dictionary:If the archive is encrypted, the system prepares a common weak-password list by default. You can also generate numeric dictionaries with 4 to 6 digits using one click, or paste your own password list into the text box with one password per line.
  • Start testing:Click the start batch test button and the utility will run quickly in the background while showing the current progress and the password being tested.
  • Get results:As soon as the correct password is found, the test stops and highlights it immediately. If the entire dictionary is tested without success, the utility will suggest trying a more complex list.

Frequently asked questions

验证密码时会将我的文件和密码上传吗?

绝对不会。我们的工具完全基于现代 HTML5 和纯前端 JavaScript 技术构建。您的压缩包文件和输入的所有密码测试,都仅仅在您的本地设备内存中运行和校验,没有任何数据会通过网络传输到我们的服务器。您可以完全放心地测试您的私密文件。

密码验证的速度快吗?需要完全解压吗?

非常快。我们采用了底层“探针”技术。如果压缩包是文件级加密,工具只会尝试解密文件头的一小段数据来验证密码的正确性;如果是目录级全局加密,则仅验证目录树权限。无论文件有多大,都不需要执行漫长的全量解压过程,通常在毫秒级即可返回验证结果。

这个工具可以用来“破解”或“暴力猜解”密码吗?

不可以。本工具的设计初衷是为了方便用户在已知多个可能密码的情况下,进行快速的人工校验测试。它不提供自动化的暴力穷举或字典破解功能。如果您完全忘记了密码,请尝试回想常用的密码组合,或寻求专业的数据恢复帮助。
