Question about NameFilter

[KKacer]

First, congratulations for the great work,

Second, I have 2 questions which want to ask here:

Can you please provide a sample on using your NameFilter for creating a zip?
Let's imagine we want to Zip a whole folder containing some codes, I want to
exclude any folder named "bin" and "obj" and their contents.

I had a successful build without using any filters, not too good with regex, and couldn't find examples about this topic for your product.

My used code:

var zip = new FastZip
{
    Password = ZipPass, CreateEmptyDirectories = true, UseZip64 = UseZip64.On
};
zip.CreateZip(OutputZipFullName, ZipInputDir, true, "");

In addition maybe an extra optional parameter named "exclude" to be implemented on FastZip, can be helpful.

---

My second question, which I think could be an easier one, and guess you already implemented it is: I also want to use AES 256 as the encryption of this zip file, how/where can I tell the SharpZipLib to use it as the encryption algorithm?

Regards.

There are a few examples of using FastZip with filters on the Wiki page at https://github.com/icsharpcode/SharpZipLib/wiki/FastZip#-using-the-filefilter-parameter. The string filter parameters on CreateZip can actually be a list of regular expressions rather than just a single one, and should support both including and excluding files.

As it stands now, FastZip unfortunately doesn't directly support creation of zip files with AES encryption - there is some discussion about that in #454 and #380 (you can however create AES encrypted zips using ZipOutputStream.)

Solved my issue with exclusions right after,
And about AES, yes I saw those 2 posts also,
And as you said I am already using ZipOutputStream,
but still didn't find where/how I should apply it.

[Numpsy]

If you're adding entries to ZipOutputStream and want to AES encrypt them, you can set the AESKeySize property of ZipEntry to 128 or 256 before calling PutNextEntry

FastZip has now been extended with a new EntryEncryptionMethod property that enables it to directly create AES encrypted zips, and it also has new variants of CreateZip that take the filters as instances of IScanFilter rather than strings, which allow for greater flexibility in how filtering is done.
