7-ZIP 命令创建和提取一个密码保护的 ZIP 文件在 Windows？

在 Mac/Linux 上压缩/解压密码保护的压缩文件，我使用: 邮编:

zip -P password -r encrypted.zip folderIWantToZip

解开拉链:

unzip -P password encrypted.zip

Windows 上命令行上的等效命令是什么(假设已经安装了7zip) ？

我一直在研究，发现不可能使用 Javazip4j 库进行密码加密。Windows 也没有像 Mac/Linux 那样的 zip 命令提示符

From http://www.dotnetperls.com:

7z a secure.7z * -pSECRET

Where: 

7z        : name and path of 7-Zip executable
a         : add to archive
secure.7z : name of destination archive
*         : add all files from current directory to destination archive
-pSECRET  : specify the password "SECRET"

To open :

7z x secure.7z

Then provide the SECRET password

Note: If the password contains spaces or special characters, then enclose it with single quotes

7z a secure.7z * -p"pa$$word @|"

I'm maybe a little bit late but I'm currently trying to develop a program which can brute force a password protected zip archive. First I tried all commands I found in the internet to extract it through cmd... But it never worked....Every time I tried it, the cmd output said, that the key was wrong but it was right. I think they just disenabled this function in a current version.

What I've done to Solve the problem was to download an older 7zip version(4.?) and to use this for extracting through cmd.

This is the command: "C:/Program Files (86)/old7-zip/7z.exe" x -pKey "C:/YOURE_ZIP_PATH"

The first value("C:/Program Files (86)/old7-zip/7z.exe") has to be the path where you have installed the old 7zip to. The x is for extract and the -p For you're password. Make sure you put your password without any spaces behind the -p! The last value is your zip archive to extract. The destination where the zip is extracted to will be the current path of cmd. You can change it with: cd YOURE_PATH

Now I let execute this command through java with my password trys. Then I check the error output stream of cmd and if it is null-> then the password is right!

To fully script-automate:

Create:

7z -mhc=on -mhe=on -pPasswordHere a %ZipDest% %WhatYouWantToZip%

Unzip:

7z x %ZipFile% -pPasswordHere

(Depending, you might need to: Set Path=C:\Program Files\7-Zip;%Path% )

General Syntax:

7z a archive_name target parameters

Check your 7-Zip dir. Depending on the release you have, 7z may be replaced with 7za in the syntax.

Parameters:

  • -p encrypt and prompt for PW.
  • -pPUT_PASSWORD_HERE (this replaces -p) if you want to preset the PW with no prompt.
  • -mhe=on to hide file structure, otherwise file structure and names will be visible by default.

Eg. This will prompt for a PW and hide file structures:

7z a archive_name target -p -mhe=on

Eg. No prompt, visible file structure:

7z a archive_name target -pPUT_PASSWORD_HERE

And so on. If you leave target blank, 7z will assume * in current directory and it will recurs directories by default.
