# Minizip 2.3.3
This library is a refactoring of the minizip contribution found in the zlib distribution and is supported on Windows, macOS, and Linux. The motivation for this work has been the inclusion of advanced features, improvements in code maintainability and readability, and the reduction of duplicate code. It is based on the original work of [Gilles Vollant](http://www.winimage.com/zLibDll/minizip.html) that has been contributed to by many people over the years.
Dev: ![Dev Branch Status](https://travis-ci.org/nmoinvaz/minizip.svg?branch=dev)
Master: ![Master Branch Status](https://travis-ci.org/nmoinvaz/minizip.svg?branch=master)
For my older fork of this library checkout the [1.2](https://github.com/nmoinvaz/minizip/tree/1.2) branch.
For the original work maintained by Mark Adler checkout the zlib minizip [contrib](https://github.com/madler/zlib/tree/master/contrib/minizip).

## Features
### Compression Methods
#### BZIP2
+ Requires ``cmake . -DUSE_BZIP2=ON`` or ``#define HAVE_BZIP2``
+ Requires [BZIP2](http://www.bzip.org/) library
#### LZMA
+ Requires ``cmake . -DUSE_LZMA=ON`` or ``#define HAVE_LZMA``
+ Requires [liblzma](https://tukaani.org/xz/) library
### Encryption
#### [WinZIP AES Encryption](https://www.winzip.com/aes_info.htm)
+ Requires ``cmake . -DUSE_AES=ON`` or ``#define HAVE_AES``
+ Requires Brian Gladman's [AES](https://github.com/BrianGladman/aes) and [SHA](https://github.com/BrianGladman/sha) libraries
When zipping with a password it will always use AES 256-bit encryption.
When unzipping it will use AES decryption only if necessary.
#### Disabling All Encryption
To disable encryption use the following cmake commands:
```
cmake . -DUSE_AES=OFF
cmake . -DUSE_PKCRYPT=OFF
```
### NTFS Timestamps
Support has been added for UTC last modified, last accessed, and creation dates.
### Streams
This library has been refactored around streams.
#### Memory Streaming
To unzip from a zip file in memory pass the memory stream to the open function.
```
uint8_t *zip_buffer = NULL;
int32_t zip_buffer_size = 0;
void *mem_stream = NULL;
// fill zip_buffer with zip contents
mz_stream_mem_create(&mem_stream);
mz_stream_mem_set_buffer(mem_stream, zip_buffer, zip_buffer_size);
mz_stream_open(mem_stream, NULL, MZ_OPEN_MODE_READ);
void *zip_handle = mz_zip_open(mem_stream, MZ_OPEN_MODE_READ);
// do unzip operations
mz_stream_mem_delete(&mem_stream);
```
To create a zip file in memory first create a growable memory stream and pass it to the open function.
```
void *mem_stream = NULL;
mz_stream_mem_create(&mem_stream);
mz_stream_mem_set_grow_size(mem_stream, (128 * 1024));
mz_stream_open(mem_stream, NULL, MZ_OPEN_MODE_CREATE);
void *zip_handle = mz_zip_open(mem_stream, MZ_OPEN_MODE_WRITE);
// do unzip operations
mz_stream_mem_delete(&mem_stream);
```
For a complete example, see test_zip_mem() in [test.c](https://github.com/nmoinvaz/minizip/blob/master/test/test.c).
#### Buffered Streaming
By default the library will read bytes typically one at a time. The buffered stream allows for buffered read and write operations to improve I/O performance.
```
void *stream = NULL;
void *buf_stream = NULL;
mz_stream_os_create(&stream)
// do open os stream
mz_stream_buffered_create(&buf_stream);
mz_stream_buffered_open(buf_stream, NULL, MZ_OPEN_MODE_READ);
mz_stream_buffered_set_base(buf_stream, stream);
void *zip_handle = mz_zip_open(buf_stream, MZ_OPEN_MODE_READ);
```
#### Disk Splitting Stream
To create an archive with multiple disks use the disk splitting stream and supply a disk size value in bytes.
```
void *stream = NULL;
void *split_stream = NULL;
mz_stream_os_create(&stream);
mz_stream_split_create(&split_stream);
mz_stream_split_set_prop_int64(split_stream, MZ_STREAM_PROP_DISK_SIZE, 64 * 1024);
mz_stream_set_base(split_stream, stream);
mz_stream_open(split_stream, path..
void *zip_handle = mz_zip_open(split_stream, MZ_OPEN_MODE_WRITE);
```
### Windows RT
+ Requires ``#define MZ_USE_WINRT_API``
## Limitations
+ Archives are required to have a central directory.
+ Central directory header values should be correct and it is necessary for the compressed size to be accurate for AES encryption.
+ Central directory encryption is not supported due to licensing restrictions mentioned by PKWARE in their zip appnote.
+ Central directory is the only data stored on the last disk of a split-disk archive and doesn't follow disk size restrictions.

Issue Date: 20/12/2007
This file contains the compilation options for AES (Rijndael) and code
that is common across encryption, key scheduling and table generation.
OPERATION
These source code files implement the AES algorithm Rijndael designed by
Joan Daemen and Vincent Rijmen. This version is designed for the standard
block size of 16 bytes and for key sizes of 128, 192 and 256 bits (16, 24
and 32 bytes).
This version is designed for flexibility and speed using operations on
32-bit words rather than operations on bytes. It can be compiled with
either big or little endian internal byte order but is faster when the
native byte order for the processor is used.
THE CIPHER INTERFACE
The cipher interface is implemented as an array of bytes in which lower
AES bit sequence indexes map to higher numeric significance within bytes.
uint8_t (an unsigned 8-bit type)
uint32_t (an unsigned 32-bit type)
struct aes_encrypt_ctx (structure for the cipher encryption context)
struct aes_decrypt_ctx (structure for the cipher decryption context)
AES_RETURN the function return type
C subroutine calls:
AES_RETURN aes_encrypt_key128(const unsigned char *key, aes_encrypt_ctx cx[1]);
AES_RETURN aes_encrypt_key192(const unsigned char *key, aes_encrypt_ctx cx[1]);
AES_RETURN aes_encrypt_key256(const unsigned char *key, aes_encrypt_ctx cx[1]);
AES_RETURN aes_encrypt(const unsigned char *in, unsigned char *out,
const aes_encrypt_ctx cx[1]);
AES_RETURN aes_decrypt_key128(const unsigned char *key, aes_decrypt_ctx cx[1]);
AES_RETURN aes_decrypt_key192(const unsigned char *key, aes_decrypt_ctx cx[1]);
AES_RETURN aes_decrypt_key256(const unsigned char *key, aes_decrypt_ctx cx[1]);
AES_RETURN aes_decrypt(const unsigned char *in, unsigned char *out,
const aes_decrypt_ctx cx[1]);
IMPORTANT NOTE: If you are using this C interface with dynamic tables make sure that
you call aes_init() before AES is used so that the tables are initialised.

/* 1. BYTE ORDER WITHIN 32 BIT WORDS
The fundamental data processing units in Rijndael are 8-bit bytes. The
input, output and key input are all enumerated arrays of bytes in which
bytes are numbered starting at zero and increasing to one less than the
number of bytes in the array in question. This enumeration is only used
for naming bytes and does not imply any adjacency or order relationship
from one byte to another. When these inputs and outputs are considered
as bit sequences, bits 8*n to 8*n+7 of the bit sequence are mapped to
byte[n] with bit 8n+i in the sequence mapped to bit 7-i within the byte.
In this implementation bits are numbered from 0 to 7 starting at the
numerically least significant end of each byte (bit n represents 2^n).
However, Rijndael can be implemented more efficiently using 32-bit
words by packing bytes into words so that bytes 4*n to 4*n+3 are placed
into word[n]. While in principle these bytes can be assembled into words
in any positions, this implementation only supports the two formats in
which bytes in adjacent positions within words also have adjacent byte
numbers. This order is called big-endian if the lowest numbered bytes
in words have the highest numeric significance and little-endian if the
opposite applies.
This code can work in either order irrespective of the order used by the
machine on which it runs. Normally the internal byte order will be set
to the order of the processor on which the code is to be run but this
define can be used to reverse this in special situations
WARNING: Assembler code versions rely on PLATFORM_BYTE_ORDER being set.
This define will hence be redefined later (in section 4) if necessary

/* 4. FAST INPUT/OUTPUT OPERATIONS.
On some machines it is possible to improve speed by transferring the
bytes in the input and output arrays to and from the internal 32-bit
variables by addressing these arrays as if they are arrays of 32-bit
words. On some machines this will always be possible but there may
be a large performance penalty if the byte arrays are not aligned on
the normal word boundaries. On other machines this technique will
lead to memory access errors when such 32-bit word accesses are not
properly aligned. The option SAFE_IO avoids such problems but will
often be slower on those machines that support misaligned access
(especially so if care is taken to align the input and output byte
arrays on 32-bit word boundaries). If SAFE_IO is not defined it is
assumed that access to byte arrays as if they are arrays of 32-bit
words will not cause problems when such accesses are misaligned.

Issue Date: 20/12/2007
This file contains the code for declaring the tables needed to implement
AES. The file aesopt.h is assumed to be included before this header file.
If there are no global variables, the definitions here can be used to put
the AES tables in a structure so that a pointer can then be added to the
AES context to pass them to the AES routines that need them. If this
facility is used, the calling program has to ensure that this pointer is
managed appropriately. In particular, the value of the t_dec(in,it) item
in the table structure must be set to zero in order to ensure that the
tables are initialised. In practice the three code sequences in aeskey.c
that control the calls to aes_init() and the aes_init() routine itself will
have to be changed for a specific implementation. If global variables are
available it will generally be preferable to use them with the precomputed
STATIC_TABLES option that uses static global tables.
The following defines can be used to control the way the tables
are defined, initialised and used in embedded environments that
require special features for these purposes
the 't_dec' construction is used to declare fixed table arrays
the 't_set' construction is used to set fixed table values
the 't_use' construction is used to access fixed table values
256 byte tables:
t_xxx(s,box) => forward S box
t_xxx(i,box) => inverse S box
256 32-bit word OR 4 x 256 32-bit word tables:
t_xxx(f,n) => forward normal round
t_xxx(f,l) => forward last round
t_xxx(i,n) => inverse normal round
t_xxx(i,l) => inverse last round
t_xxx(l,s) => key schedule table
t_xxx(i,m) => key schedule table
Other variables and tables:
t_xxx(r,c) => the rcon table

Issue Date: 20/12/2007
The unsigned integer types defined here are of the form uint_<nn>t where
<nn> is the length of the type; for example, the unsigned 32-bit type is
'uint32_t'. These are NOT the same as the 'C99 integer types' that are
defined in the inttypes.h and stdint.h headers since attempts to use these
types have shown that support for them is still highly variable. However,
since the latter are of the form uint<nn>_t, a regular expression search
and replace (in VC++ search on 'uint_{:z}t' and replace with 'uint\1_t')
can be used to convert the types used here to the C99 standard types.

one of the generated Huffman code words is longer than
maxLen, which up to and including version 1.0.2 was 20 bits,
which is extremely unlikely. In version 1.0.3 maxLen was
changed to 17 bits, which has minimal effect on compression
ratio, but does mean this scaling step is used from time to
time, enough to verify that it works.
This means that bzip2-1.0.3 and later will only produce
Huffman codes with a maximum length of 17 bits. However, in
order to preserve backwards compatibility with bitstreams
produced by versions pre-1.0.3, the decompressor must still
handle lengths of up to 20. */

/**
* \file api/lzma.h
* \brief The public API of liblzma data compression library
*
* liblzma is a public domain general-purpose data compression library with
* a zlib-like API. The native file format is .xz, but also the old .lzma
* format and raw (no headers) streams are supported. Multiple compression
* algorithms (filters) are supported. Currently LZMA2 is the primary filter.
*
* liblzma is part of XZ Utils <http://tukaani.org/xz/>. XZ Utils includes
* a gzip-like command line tool named xz and some other tools. XZ Utils
* is developed and maintained by Lasse Collin.
*
* Major parts of liblzma are based on Igor Pavlov's public domain LZMA SDK
* <http://7-zip.org/sdk.html>.
*
* The SHA-256 implementation is based on the public domain code found from
* 7-Zip <http://7-zip.org/>, which has a modified version of the public
* domain SHA-256 code found from Crypto++ <http://www.cryptopp.com/>.
* The SHA-256 code in Crypto++ was written by Kevin Springle and Wei Dai.

/*****************************
* Required standard headers *
*****************************/
/*
* liblzma API headers need some standard types and macros. To allow
* including lzma.h without requiring the application to include other
* headers first, lzma.h includes the required standard headers unless
* they already seem to be included already or if LZMA_MANUAL_HEADERS
* has been defined.
*
* Here's what types and macros are needed and from which headers:
* - stddef.h: size_t, NULL
* - stdint.h: uint8_t, uint32_t, uint64_t, UINT32_C(n), uint64_C(n),
* UINT32_MAX, UINT64_MAX
*
* However, inttypes.h is a little more portable than stdint.h, although
* inttypes.h declares some unneeded things compared to plain stdint.h.
*
* The hacks below aren't perfect, specifically they assume that inttypes.h
* exists and that it typedefs at least uint8_t, uint32_t, and uint64_t,
* and that, in case of incomplete inttypes.h, unsigned int is 32-bit.
* If the application already takes care of setting up all the types and
* macros properly (for example by using gnulib's stdint.h or inttypes.h),
* we try to detect that the macros are already defined and don't include
* inttypes.h here again. However, you may define LZMA_MANUAL_HEADERS to
* force this file to never include any system headers.
*
* Some could argue that liblzma API should provide all the required types,
* for example lzma_uint64, LZMA_UINT64_C(n), and LZMA_UINT64_MAX. This was
* seen as an unnecessary mess, since most systems already provide all the
* necessary types and macros in the standard headers.

*
* - Initialize a coder to the lzma_stream, for example by using

* - In contrast to zlib, strm->next_in and strm->next_out are
* ignored by all initialization functions, thus it is safe
* to not initialize them yet.
* - The initialization functions always set strm->total_in and
* strm->total_out to zero.
* - If the initialization function fails, no memory is left allocated

// store the actual literals as they do with length-distance pairs.
//
// Algorithms such as LZMA2 first try to compress a chunk, and then check
// if the encoded result is smaller than the uncompressed one. If the chunk
// was uncompressible, it is better to store it in uncompressed form in
// the output stream. To do this, the whole uncompressed chunk has to be

// LZMA encodes match distances by storing the highest two bits using
// a six-bit value [0, 63], and then the missing lower bits.
// Dictionary size is also stored using this encoding in the .xz
// file format header.
//
// fastpos.h provides a way to quickly find out the correct six-bit
// values. The following table gives some examples of this encoding:
//
// dist return
// 0 0
// 1 1
// 2 2
// 3 3
// 4 4
// 5 4
// 6 5
// 7 5

// 24 9
// 25 9
// ... ...
//
//
// Provided functions or macros
// ----------------------------
//
// get_dist_slot(dist) is the basic version. get_dist_slot_2(dist)
// assumes that dist >= FULL_DISTANCES, thus the result is at least
// FULL_DISTANCES_BITS * 2. Using get_dist_slot(dist) instead of
// get_dist_slot_2(dist) would give the same result, but get_dist_slot_2(dist)
// should be tiny bit faster due to the assumption being made.
//
//
// Size vs. speed
// --------------
//
// With some CPUs that have fast BSR (bit scan reverse) instruction, the
// size optimized version is slightly faster than the bigger table based
// approach. Such CPUs include Intel Pentium Pro, Pentium II, Pentium III
// and Core 2 (possibly others). AMD K7 seems to have slower BSR, but that
// would still have speed roughly comparable to the table version. Older
// x86 CPUs like the original Pentium have very slow BSR; on those systems
// the table version is a lot faster.
//
// On some CPUs, the table version is a lot faster when using position
// dependent code, but with position independent code the size optimized
// version is slightly faster. This occurs at least on 32-bit SPARC (no
// ASM optimizations).
//
// I'm making the table version the default, because that has good speed
// on all systems I have tried. The size optimized version is sometimes
// slightly faster, but sometimes it is a lot slower.
