Encrypting a Zip File

Please read about encryption before using this feature.

To encrypt or re-encrypt all of the files in an open WinZip® file (.zip or .zipx):

  1. In the main WinZip window, select all of the files in the WinZip file (Ctrl+A is a handy keyboard shortcut).
  2. Click Encrypt In the Tools tab .
  3. In the Encrypt dialog, enter the password in the Enter password and Re-enter password (for confirmation) fields and then click OK.

 

The type of encryption that is used depends on the encryption settings in the Encryption tab of the WinZip Settings dialog.

Any files in the Zip file that are already encrypted must first be decrypted before they are re-encrypted using the method and password you specified. WinZip will first try to decrypt the files using the current encryption password; if a file cannot be decrypted with this password, WinZip will ask you for the correct decryption password. If you are unable to supply the correct password, the file will be skipped, and it will remain unchanged in the Zip file.
