This code is a modified version of crypting code in Infozip distribution
The encryption/decryption parts of this source code (as opposed to the
non-echoing password parts) were originally written in Europe. The
whole source package can be freely distributed, including from the USA.
(Prior to January 2000, re-export from the US was a violation of US law.)
This encryption code is a direct transcription of the algorithm from
Roger Schlafly, described by Phil Katz in the file appnote.txt. This
file (appnote.txt) is distributed with the PKZIP program (even in the
version without encryption capabilities).
If you don't need crypting in your application, just define symbols
NOCRYPT and NOUNCRYPT.
This code support the "Traditional PKWARE Encryption".
The new AES encryption added on Zip format by Winzip (see the page

Modifications for Zip64 support
Copyright (C) 2009-2010 Mathias Svensson ( http://result42.com )
Modified by Sergey A. Tachenov to allow QIODevice API usage.
For more info read MiniZip_info.txt
Changes
Oct-2009 - Defined ZPOS64_T to fpos_t on windows and u_int64_t on linux. (might need to find a better why for this)
Oct-2009 - Change to fseeko64, ftello64 and fopen64 so large files would work on linux.
More if/def section may be needed to support other platforms
Oct-2009 - Defined fxxxx64 calls to normal fopen/ftell/fseek so they would compile on windows.
(but you should use iowin32.c for windows instead)

/// A file inside ZIP archive.
/** \class QuaZipFile quazipfile.h
* This is the most interesting class. Not only it provides C++
* interface to the ZIP/UNZIP package, but also integrates it with Qt by
* subclassing QIODevice. This makes possible to access files inside ZIP
* archive using QTextStream or QDataStream, for example. Actually, this
* is the main purpose of the whole QuaZIP library.
*
* You can either use existing QuaZip instance to create instance of
* this class or pass ZIP archive file name to this class, in which case
* it will create internal QuaZip object. See constructors' descriptions
* for details. Writing is only possible with the existing instance.
*
* Note that due to the underlying library's limitation it is not
* possible to use multiple QuaZipFile instances to open several files
* in the same archive at the same time. If you need to write to
* multiple files in parallel, then you should write to temporary files
* first, then pack them all at once when you have finished writing. If
* you need to read multiple files inside the same archive in parallel,
* you should extract them all into a temporary directory first.
*
* \section quazipfile-sequential Sequential or random-access?
*
* At the first thought, QuaZipFile has fixed size, the start and the
* end and should be therefore considered random-access device. But
* there is one major obstacle to making it random-access: ZIP/UNZIP API
* does not support seek() operation and the only way to implement it is
* through reopening the file and re-reading to the required position,
* but this is prohibitively slow.
*
* Therefore, QuaZipFile is considered to be a sequential device. This
* has advantage of availability of the ungetChar() operation (QIODevice
* does not implement it properly for non-sequential devices unless they
* support seek()). Disadvantage is a somewhat strange behaviour of the
* size() and pos() functions. This should be kept in mind while using
* this class.

*
* \a zip is the pointer to the existing QuaZip object. This
* QuaZipFile object then can be used to read current file in the
* \a zip or to write to the file inside it.
*
* \warning Using this constructor for reading current file can be
* tricky. Let's take the following example:
* \code
* QuaZip zip("archive.zip");
* zip.open(QuaZip::mdUnzip);
* zip.setCurrentFile("file-in-archive");
* QuaZipFile file(&zip);
* file.open(QIODevice::ReadOnly);
* // ok, now we can read from the file
* file.read(somewhere, some);
* zip.setCurrentFile("another-file-in-archive"); // oops...
* QuaZipFile anotherFile(&zip);
* anotherFile.open(QIODevice::ReadOnly);
* anotherFile.read(somewhere, some); // this is still ok...
* file.read(somewhere, some); // and this is NOT
* \endcode
* So, what exactly happens here? When we change current file in the
* \c zip archive, \c file that references it becomes invalid
* (actually, as far as I understand ZIP/UNZIP sources, it becomes
* closed, but QuaZipFile has no means to detect it).
*
* Summary: do not close \c zip object or change its current file as
* long as QuaZipFile is open. Even better - use another constructors
* which create internal QuaZip instances, one per object, and
* therefore do not cause unnecessary trouble. This constructor may
* be useful, though, if you already have a QuaZip instance and do
* not want to access several files at once. Good example:
* \code
* QuaZip zip("archive.zip");
* zip.open(QuaZip::mdUnzip);
* // first, we need some information about archive itself
* QByteArray comment=zip.getComment();
* // and now we are going to access files inside it
* QuaZipFile file(&zip);
* for(bool more=zip.goToFirstFile(); more; more=zip.goToNextFile()) {
* file.open(QIODevice::ReadOnly);
* // do something cool with file here
* file.close(); // do not forget to close!
* }
* zip.close();
* \endcode

Changes
Oct-2009 - Mathias Svensson - Remove old C style function prototypes
Oct-2009 - Mathias Svensson - Added Zip64 Support when creating new file archives
Oct-2009 - Mathias Svensson - Did some code cleanup and refactoring to get better overview of some functions.
Oct-2009 - Mathias Svensson - Added zipRemoveExtraInfoBlock to strip extra field data from its ZIP64 data
It is used when recreting zip archive with RAW when deleting items from a zip.
ZIP64 data is automaticly added to items that needs it, and existing ZIP64 data need to be removed.
Oct-2009 - Mathias Svensson - Added support for BZIP2 as compression mode (bzip2 lib is required)
Jan-2010 - back to unzip and minizip 1.0 name scheme, with compatibility layer

/** \class QuaZip quazip.h
* This class implements basic interface to the ZIP archive. It can be
* used to read table contents of the ZIP archive and retreiving
* information about the files inside it.
*
* You can also use this class to open files inside archive by passing
* pointer to the instance of this class to the constructor of the
* QuaZipFile class. But see QuaZipFile::QuaZipFile(QuaZip*, QObject*)
* for the possible pitfalls.
*
* This class is indended to provide interface to the ZIP subpackage of
* the ZIP/UNZIP package as well as to the UNZIP subpackage. But
* currently it supports only UNZIP.
*
* The use of this class is simple - just create instance using
* constructor, then set ZIP archive file name using setFile() function
* (if you did not passed the name to the constructor), then open() and
* then use different functions to work with it! Well, if you are
* paranoid, you may also wish to call close before destructing the
* instance, to check for errors on close.
*
* You may also use getUnzFile() and getZipFile() functions to get the
* ZIP archive handle and use it with ZIP/UNZIP package API directly.
*
* This class supports localized file names inside ZIP archive, but you
* have to set up proper codec with setCodec() function. By default,
* locale codec will be used, which is probably ok for UNIX systems, but
* will almost certainly fail with ZIP archives created in Windows. This
* is because Windows ZIP programs have strange habit of using DOS
* encoding for file names in ZIP archives. For example, ZIP archive
* with cyrillic names created in Windows will have file names in \c
* IBM866 encoding instead of \c WINDOWS-1251. I think that calling one
* function is not much trouble, but for true platform independency it
* would be nice to have some mechanism for file name encoding auto
* detection using locale information. Does anyone know a good way to do
* it?

* argument. See setComment() if you need to set global comment.
*
* If the ZIP file is accessed via explicitly set QIODevice, then
* this device is opened in the necessary mode. If the device was

* open mode is compatible to the mode needed for the requested operation.
* If necessary, seeking is performed to position the device properly.
*
* \return \c true if successful, \c false otherwise.
*
* \note ZIP/UNZIP API open calls do not return error code - they
* just return \c NULL indicating an error. But to make things
* easier, quazip.h header defines additional error code \c
* UNZ_ERROROPEN and getZipError() will return it if the open call
* of the ZIP/UNZIP API returns \c NULL.
*
* Argument \a ioApi specifies IO function set for ZIP/UNZIP
* package to use. See unzip.h, zip.h and ioapi.h for details. Note
* that IO API for QuaZip is different from the original package.
* The file path argument was changed to be of type \c voidpf, and
* QuaZip passes a QIODevice pointer there. This QIODevice is either
* set explicitly via setIoDevice() or the QuaZip(QIODevice*)
* constructor, or it is created internally when opening the archive
* by its file name. The default API (qioapi.cpp) just delegates
* everything to the QIODevice API. Not only this allows to use a
* QIODevice instead of file name, but also has a nice side effect
* of raising the file size limit from 2G to 4G (in non-zip64 archives).
*
* \note If the zip64 support is needed, the ioApi argument \em must be NULL
* because due to the backwards compatibility issues it can be used to
* provide a 32-bit API only.
*
* In short: just forget about the \a ioApi argument and you'll be

* but at least it makes your programs work instead of crashing. Note that
