How To Open Secure Zip Files
If the archive is strongly encrypted (set by default on PKWARE products), you may get this error when trying to open in Windows Compressed Folders (the Windows default) as it does not support strong encryption. If you are prompted for password and not passphrase, this is an indication that the file is not being opened by PKZIP or SecureZIP

I put some files into an encrypted archive with Secure Zip (was using a computer at another organization) and emailed them to some people. None of them have Secure Zip (nor do I on any of my own computers) and none of us can open them. Neither 7zip nor Winzip can open these archives.
We often compress or ZIP files on Mac to save space, but we should also take more care in what we're storing. Chances are you're compressing files that hold sensitive information. Zipping files is a great method for making the data inside more difficult to access, but that compression doesn't prevent prying eyes from taking a look.
There's a simple way to zip and password protect folders and files via Terminal. It takes some unique commands, but it's the most straightforward method to password protect ZIP file and folders on Mac. Here's how it's done:
That's all it takes! You'll now see a compressed file on your desktop. Double-clicking the file or folder to open it will prompt you for the password you typed into Terminal, so be sure to keep your passwords in a safe location.
BetterZip works via a structure it appropriately calls archives, which are projects for compressing and encrypting backups of your files and folders. You can add as many files or folders to an archive as you like, and choose where you'd like your archive saved after it's compressed.
Where BetterZip stands apart is it allows you the option to edit files within an archive. If the app detects you actually made any changes to a document, it offers you the option to update (re-compress) your archive. You can also search within archives.
When it comes to encryption, BetterZip is also better than the alternatives for compressed files. When you create passwords for zipped files archived in BetterZip, it saves those passwords for you in its password manager. When you attempt to open an encrypted file or folder in betterZip, it will attempt to use the saved passwords in its password manager. This helps you create secure passwords others can't possibly guess, but also helps make it easy to edit or view files as you won't have to remember passwords or deal with external password managers.
Archiver has a really clean drag and drop interface that allows you to drag any file or folder onto its app window, then press a single button to create a zipped archive of your documents. It also supports compressing multiple files or folders, and will compress them individually in a batch process.
There are a few key ways to open a password protected file on your Mac. If you know the password and just need to view a file, double-clicking it and entering the password will open the file up and uncompress it.
Double-clicking a folder or file and Terminal are both destructive to your compression, meaning the encrypted file is unzipped after you open it. BetterZip doesn't disturb your folder or file's compression. The app allows you to view and edit files within a zipped folder or zipped files themselves. So long as you use BetterZip, you can perform many functions without disturbing the compression, and the app has a 'save' feature if you do edit documents.
Zipping and encrypting files or folders on your Mac is important. It's one of the best way to safeguard important documents you won't need to access often, and sensitive personal information that can be tucked away on an external drive. Photos, tax documents, personal files, and other such items are perfect candidates for encryption on Mac.
Archiver and BetterZip are two great apps that do a sensational job of encrypting and compressing files in a wide array of formats. Power users may find BetterZip's ease of use for accessing zipped files very attractive, while others may appreciate Archiver's drag and drop interface and simplicity.
Either way, we think these apps are far better options than Terminal, which is fussy and linear. One wrong keystroke in Terminal can cause issues, so it's better to have a visual interface via an app when dealing with sensitive files or folders.
Most of us prefer to password protect a Zip file to make it impossible for unauthorized persons to access our files. It will be truly easy to unzip a password protected Zip file if you know the password.

The good news is that you don't need to worry about a password getting in your way. There are quite a number of methods you can use to accomplishing your goals. Let's check them out.
The most effective, safest and easiest way to extract a password protected Zip file is using a professional Zip password unlocker that is both robust in its operation and guarantees the security of your data.

I'm trying to extract contents of password protected zip files that have been zipped using PKWARE SecureZip in Python.Modules that I've tried already are zipfile and pyzipper. But methods of these modules always return 'NotImplementedError: strong encryption (flag bit 6)'.
I have tried to work around this by checking for ways to extract these zip files from the command prompt.However, I don't see 'pkzipc.exe' in my installation directory (as explained in this document).
