WinZip® uses the standard Zip 2.0 encryption format, a format that is also supported by most other Zip utilities.
Password protecting files in a Zip file provides a measure of protection against casual users who do not have the password and are trying to determine the contents of the files. However, the Zip 2.0 encryption format is known to be relatively weak, and cannot be expected to provide protection from individuals with access to specialized password recovery tools.
You should not rely on WinZip password protection to provide strong security for your data. If you have important security requirements for your data, you should look into more robust cryptography solutions.
Using password security while using the Extract, Test, CheckOut, or Install features:
If you use the Extract, Test, CheckOut, or Install features on a password protected archive, you will automatically be prompted for the password.
Using password security while adding or updating an archive:
To password protect files, it is important to specify the password AFTER opening or creating an archive and BEFORE adding the files.
Follow these steps to password protect files in an archive:
1. Open or create an archive. If you are using the New Archive dialog box, check the Add Dialog checkbox at the bottom of the dialog box.
2. In the Add dialog box, click the Password button, and type a password.Notes
· The main WinZip window lists password protected files with a plus sign following the filename.
· In addition to the methods specified above, you can choose Password from the Options menu to specify a password.
· Use the Mask password checkbox to control whether the password is hidden while typed. If you check this option, you will have to re-type the password for confirmation (to avoid typographical errors).
· Passwords are cleared (reset so that no password is in effect) when an archive is closed or another archive is opened.
· Passwords can also be used for ARJ files; in this case, the external ARJ program is responsible for all data encryption.
· In general, longer passwords (for example, passwords with 8 or more characters) are more secure than shorter passwords, and passwords that contain a mixture of alphabetic characters, numeric characters, and punctuation characters are more secure than passwords containing only alphabetic characters.
· Be sure to remember any passwords you use, so that you can extract your files!
