Hi,

Thank you for your interest in Syncfusion products.

Currently we don't have support for this feature. Please let me know if you have any other questions.

Best Regards,

I just thought I'd ask if the ability to open or save password protected zip files has been added to ZipArchive yet.

It's been almost three year since the last post by SyncFusion.
Has password pretection been added to ZipArchive yet?
Thanks.

Hi Howard,

Thank you for your interest in Syncfusion products.

The feature to password protect zip files created using Compression.Base is not yet available. We will let you know once it is added in our library.

Please let me know if you have any questions.

Regards,
Geetha

How about now?

Hi Mike,
 
Currently, we don’t have support for “Password functionality in Compression.Base”. However, we have added it to our feature request list and it will be implemented in our upcoming release 2017 Vol 4.
 
Please let us know if you have any concerns.
 
Regards,

How about now - it's been 12 years since the original request?

Hi Darren, 

Thanks for your patience. 

We have implemented the feature Password functionality in Compression.Base and included in our release version v15.3.0.26 which was rolled out in August 2017. We suggest you to use our latest version v17.4.0.39, which includes this implementation along with more bug fixes and features. 

You can download the Essential Studio 2019 Volume 4 release version v17.4.0.39 from the following link. 


Please look into the following into the following code snippets for protecting and un-protecting the Zip files. 

Code Snippet to protect a Zip file: 

ZipArchive zipArchive = new ZipArchive(); 
zipArchive.AddFile("../../Data/Template1.txt"); 
zipArchive.AddFile("../../Data/Template2.txt"); 
zipArchive.AddFile("../../Data/Template3.txt"); 
zipArchive.Protect("Syncfusion", EncryptionAlgorithm.ZipCrypto); 
zipArchive.Save("WithPasswordZipCrypto.zip"); 

Code snippet to un-protect a Zip file: 

ZipArchive zipArchive = new ZipArchive(); 
zipArchive.Open(new FileStream("../../Data/Protected.zip", FileMode.Open), false, "Syncfusion"); 
zipArchive.UnProtect(); 
zipArchive.Save("WithOutPassword.zip"); 

A simple working sample can be downloaded from the following link. 


Regards, 
Keerthi.
