How to Access Password-Protected ZIP Files

When opening a password-protected ZIP archive created with 7-Zip or similar software:

  • Double-click the ZIP file to open it with your compression tool.
  • The program will prompt you to enter the password before you can extract or view the files.
  • Enter the correct password to access the contents.
  • If the password is incorrect, extraction or viewing will be denied.

Alternative Method: Using PowerShell to Encrypt Files Before Zipping

If you prefer not to rely on third-party software for password protecting the ZIP file itself, a workaround is to encrypt files individually before compressing them. Windows 11 includes PowerShell, which can be used to encrypt files securely using built-in encryption cmdlets.

Encrypting Files with PowerShell

  • Open PowerShell as an administrator.
  • Use the Protect-CmsMessage cmdlet to encrypt files, specifying a certificate or using password-based encryption.
  • This method encrypts the file contents so that even if the ZIP file is extracted, the files remain encrypted.

Example PowerShell Command for Password-Based Encryption

“`powershell
Get-Content -Path “C:\Path\To\Your\File.txt” |
Protect-CmsMessage -To “[email protected]” -OutFile “C:\Path\To\Your\File.txt.p7m”
“`

*Note:* This example uses certificate-based encryption. For password-based encryption, additional scripting is necessary, and it is generally more complex than using dedicated compression software.

Limitations of PowerShell Encryption Method

  • Requires familiarity with certificates or advanced PowerShell scripting.
  • Does not create a password-protected ZIP file per se; rather, the files inside are encrypted.
  • Users extracting files will need the appropriate key or password to decrypt each file individually.

This method is suitable for users with advanced security requirements but is less convenient than using third-party archivers for password-protecting ZIP files directly.
