How do you Encrypt Files in a Zip file?

How do you Encrypt Files in a Zip file? WinZip can encrypt files while you Make new Zip files (.zip or .zipx) and it can also add encryption to data in existing Zip files.

Encrypt while creating Zip files

WinZip in the Default view:

  1. Click the Encrypt toggle in the Actions pane
  2. If you have not already done so, Press the Options button that now displays in the Actions pane to set the encryption level
  3. Add files to your new Zip file
  4. Enter a password when the Encrypt dialog displays
  5. Save the Zip file

WinZip in the Classic view:

  1. Press the Encrypt button in the Create/Share (Edit) tab
  2. If you have not already done so, Press Conversion Settings drop-down menu on the Settings tab and choose Encryption to set the encryption level
  3. Add files to your new Zip file
  4. Enter a password when the Encrypt dialog displays
  5. Save the Zip file

If you are making a Zip file in a folder window using the context menu (right-click), you will have the option to encrypt the files and select encryption strength if the Add dialog is displayed. If you choose to add files to an existing Zip file using Create to recently used Zip file there will be no Add dialog and therefore no opportunity to encrypt the files while they are being added. In such a case, you can encrypt files after they have been added.

One more option would be to use WinZip Express for Explorer. To do this, Press Zip and Share (WinZip Express) when you right-click. With WinZip Express you can zip, choose to encrypt and make use of many additional options such as saving to a cloud service.

Encrypting data in an existing Zip file

In the WinZip user interface:

  • Method 1:
    1. Open the Zip file
    2. Press the Encrypt toggle in the Actions pane, click Options below the toggle when it appears, and click Apply to all files in the Zip
  • Method 2:
    1. Open the Zip file
    2. Click the Tools tab
    3. Press the Encrypt button in the Selected Files section (WinZip 22.0 or later)
      For recent WinZip versions prior to 22.0, Press Selected Files, check the box next to Encrypt files, and click the Convert Selected Files button

In a Windows Explorer folder window:

  1. Right-click on the Zip file in a folder window.
  2. Choose WinZip
  3. Click Encrypt

In each case, WinZip will ask for a password and then encrypt all files currently in the Zip file. Depending on the method you use, you may or may not have the option to change the encryption strength.

If a file in the Zip file is already encrypted, it will first be decrypted and then re-encrypted using the password and encryption method you specified. WinZip will first try to decrypt the file using the current password; if the file cannot be decrypted with this password, WinZip will ask you for the correct password. If you are unable to supply the correct password, the file can be skipped, and it will remain unchanged in the Zip file. The password you entered in the Encrypt dialog box will remain active until either you delete or replace it, or you close the archive.
