open a password protected Zip file in C# code.

hello
we are developing one tool where we need to open and make password
protected zip files.
we found some solutions but they don't support password protected
things.

does any one knows about this

or any aproach for this.

We need to open password procted zip file

and then again recrate it using some other password

Thank you in advance.

What have you tried?

I'm fairly certain SharpZipLib supports this

I don't understand your issue.

Do you have to open the password protected zip file from an exe ?

Please refer this site and make use of the dll and explore your project with
this namespace.

I had the same project and it was working well with this dll.

Download it From:
www.chilkatsoft.com/refDoc/csZipRef.html

Please let me know the status.

please post your doubts and help me to explore ny knowledge.

Isn't the product you suggested just an ActiveX/COM control with a
..NET wrapper? In other words, it is unmanaged and has none of the
advantages of a .NET component?

I'm curious, because reading between the lines on their web site, you
would think that it is a .NET component, yet there is no specific
mention of managed code, written in C# / VB.NET or anything else.

Another one... is this actually a true .NET component or another
disguised ActiveX/COM that conveniently does not mention anything
about its true composition?

Apart from this, maybe...? (http://www.chilkatsoft.com/ChilkatDotNet.asp)

The Chilkat.NET components are written in Managed Visual C++ and created
specifically for
the .NET framework. They offer seamless integration with the .NET framework
class library, as
well as seamless interoperability within Chilkat.NET.

I would then say, you're right!

Must have been thinking of another company.
