I wrote a ziplib for use with another language (Blitz3D). I made sure to add decryption support so that I could encrypt my game data files with winrar and still be able to extract them in the game. I noticed that std.zip didn't have any decryption support, so I added it. It doesn't have any support for encryption (adding files to the archive and encrypting them), but that might come later. The attached file contains myzip.d, which is exactly the same as std.zip, except that the ZipArchive.expand() function no longer throws an exception if it finds an encrypted file, and it has an extra optional parameter - a char[] for the password. So to decrypt a file, you'd do something like.. ubyte[] data=zip.expand(zip.directory["test.txt"],"qwe"); Where "qwe" is the password. Note that because of the way zip encryption works, there is not necessarily a "right" or "wrong" password - use the wrong password, and it'll decrypt the file into nonsensical garbage. There is another file in the attached zip called message.txt. Try extracting it using the new expand() function with the password "walter". | ||||||||||||||||
