NArchive is a brand new fast archiver for NeoAxis that uses QuickLZ for compression and System.Security.Cryptography for encryption.
Currently the usage is pretty Spartanish but it gets the job done, new versions will be more user friendly.

To create the archive you will need to call CreateArchive method:

Code: Select all   Expand view

NArchiver.CreateArchive(string folderToArchive, bool excludeFolderName, string fileName)

folderToArchive - name of the folder to archive; includes all subfolders.
excludeFolderName - specifies whether to exclude the base folder name from the entry names in the archive.
fileName - path and name of the archive including the extension (using .na by default)

Game, ResourceEditor and MapEditor will automatically recognize .na if NArchive.dll is in same folder as they are. Password is hardcoded in NArchiver class, and extension to read is hardcoded in NArchiveFactory class.

Speed: ~14.5s for 180mb Data folder to be compressed and encrypted to 128mb.

Sorry if I'm kinda hijacking your thread, but I didn't think this was worth it's own topic

Also, as a note, if your wanting support for rar, tar, tar.gz, tar.bz2, or 7z archives, contact me (I'm usually on the irc), as I have a package setup that should be able to do it, I just have to figure out how to get NeoAxis to like .net 4.0 libraries....

Why not worthy it's own topic?

I think the encryption addition sounds handy, good to see an example implementation.
Many art asset dealers force you in their EULA to have their content in encrypted format.

How do you call CreateArchive method ?
