This is an implementation of the AES algorithm, specifically ECB, CTR and CBC mode.
Block size can be chosen in aes.h - available choices are AES128, AES192, AES256.
The implementation is verified against the test vectors in:
National Institute of Standards and Technology Special Publication 800-38A 2001 ED
ECB-AES128

NOTE: String length must be evenly divisible by 16byte (str_len % 16 == 0)
You should pad the end of the string with zeros if this is not the case.
For AES192/256 the key size is proportionally larger.

Introduction
LZ4 is lossless compression algorithm, providing compression speed >500 MB/s per core,
scalable with multi-cores CPU. It features an extremely fast decoder, with speed in
multiple GB/s per core, typically reaching RAM speed limits on multi-core systems.
The LZ4 compression library provides in-memory compression and decompression functions.
It gives full buffer control to user.
Compression can be done in:
- a single step (described as Simple Functions)
- a single step, reusing a context (described in Advanced Functions)
- unbounded multiple steps (described as Streaming compression)
lz4.h generates and decodes LZ4-compressed blocks (doc/lz4_Block_format.md).
Decompressing such a compressed block requires additional metadata.
Exact metadata depends on exact decompression function.
For the typical case of LZ4_decompress_safe(),
metadata includes block's compressed size, and maximum bound of decompressed size.
Each application is free to encode and pass such metadata in whichever way it wants.
lz4.h only handle blocks, it can not generate Frames.
Blocks are different from Frames (doc/lz4_Frame_format.md).
Frames bundle both blocks and metadata in a specified manner.
Embedding metadata is required for compressed data to be self-contained and portable.
Frame format is delivered through a companion API, declared in lz4frame.h.
The `lz4` CLI can only manage frames.

/*! In-place compression and decompression
*
* It's possible to have input and output sharing the same buffer,
* for highly constrained memory environments.
* In both cases, it requires input to lay at the end of the buffer,
* and decompression to start at beginning of the buffer.
* Buffer size must feature some margin, hence be larger than final size.
*
* |<------------------------buffer--------------------------------->|
* |<-----------compressed data--------->|
* |<-----------decompressed size------------------>|
* |<----margin---->|
*
* This technique is more useful for decompression,
* since decompressed size is typically larger,
* and margin is short.
*
* In-place decompression will work inside any buffer
* which size is >= LZ4_DECOMPRESS_INPLACE_BUFFER_SIZE(decompressedSize).
* This presumes that decompressedSize > compressedSize.
* Otherwise, it means compression actually expanded data,
* and it would be more efficient to store such data with a flag indicating it's not compressed.
* This can happen when data is not compressible (already compressed, or encrypted).
*
* For in-place compression, margin is larger, as it must be able to cope with both
* history preservation, requiring input data to remain unmodified up to LZ4_DISTANCE_MAX,
* and data expansion, which can happen when input is not compressible.
* As a consequence, buffer size requirements are much higher,
* and memory savings offered by in-place compression are more limited.
*
* There are ways to limit this cost for compression :
* - Reduce history size, by modifying LZ4_DISTANCE_MAX.
* Note that it is a compile-time constant, so all compressions will apply this limit.
* Lower values will reduce compression ratio, except when input_size < LZ4_DISTANCE_MAX,
* so it's a reasonable trick when inputs are known to be small.
* - Require the compressor to deliver a "maximum compressed size".
* This is the `dstCapacity` parameter in `LZ4_compress*()`.
* When this size is < LZ4_COMPRESSBOUND(inputSize), then compression can fail,
* in which case, the return code will be 0 (zero).
* The caller must be ready for these cases to happen,
* and typically design a backup scheme to send data uncompressed.
* The combination of both techniques can significantly reduce
* the amount of margin required for in-place compression.
*
* In-place compression can work in any buffer
* which size is >= (maxCompressedSize)
* with maxCompressedSize == LZ4_COMPRESSBOUND(srcSize) for guaranteed compression success.
* LZ4_COMPRESS_INPLACE_BUFFER_SIZE() depends on both maxCompressedSize and LZ4_DISTANCE_MAX,
* so it's possible to reduce memory requirements by playing with them.

-- About
QOI encodes and decodes images in a lossless format. Compared to stb_image and
stb_image_write QOI offers 20x-50x faster encoding, 3x-4x faster decoding and
20% better compression.
-- Synopsis
// Define `QOI_IMPLEMENTATION` in *one* C/C++ file before including this
// library to create the implementation.
#define QOI_IMPLEMENTATION
#include "qoi.h"
// Encode and store an RGBA buffer to the file system. The qoi_desc describes
// the input pixel data.
qoi_write("image_new.qoi", rgba_pixels, &(qoi_desc){
.width = 1920,
.height = 1080,
.channels = 4,
.colorspace = QOI_SRGB
});
// Load and decode a QOI image from the file system into a 32bbp RGBA buffer.
// The qoi_desc struct will be filled with the width, height, number of channels
// and colorspace read from the file header.
qoi_desc desc;
void *rgba_pixels = qoi_read("image.qoi", &desc, 4);
-- Documentation
This library provides the following functions;
- qoi_read -- read and decode a QOI file
- qoi_decode -- decode the raw bytes of a QOI image from memory
- qoi_write -- encode and write a QOI file
- qoi_encode -- encode an rgba buffer into a QOI image in memory
See the function declaration below for the signature and more information.
If you don't want/need the qoi_read and qoi_write functions, you can define
QOI_NO_STDIO before including this library.
This library uses malloc() and free(). To supply your own malloc implementation
you can define QOI_MALLOC and QOI_FREE before including this library.
This library uses memset() to zero-initialize the index. To supply your own
implementation you can define QOI_ZEROARR before including this library.
-- Data Format
A QOI file has a 14 byte header, followed by any number of data "chunks" and an
8-byte end marker.
struct qoi_header_t {
char magic[4]; // magic bytes "qoif"
uint32_t width; // image width in pixels (BE)
uint32_t height; // image height in pixels (BE)
uint8_t channels; // 3 = RGB, 4 = RGBA
uint8_t colorspace; // 0 = sRGB with linear alpha, 1 = all channels linear
};
Images are encoded row by row, left to right, top to bottom. The decoder and
encoder start with {r: 0, g: 0, b: 0, a: 255} as the previous pixel value. An
image is complete when all pixels specified by width * height have been covered.
Pixels are encoded as
- a run of the previous pixel
- an index into an array of previously seen pixels
- a difference to the previous pixel value in r,g,b
- full r,g,b or r,g,b,a values
The color channels are assumed to not be premultiplied with the alpha channel
("un-premultiplied alpha").
A running array[64] (zero-initialized) of previously seen pixel values is
maintained by the encoder and decoder. Each pixel that is seen by the encoder
and decoder is put into this array at the position formed by a hash function of
the color value. In the encoder, if the pixel value at the index matches the
current pixel, this index position is written to the stream as QOI_OP_INDEX.
The hash function for the index is:
index_position = (r * 3 + g * 5 + b * 7 + a * 11) % 64
Each chunk starts with a 2- or 8-bit tag, followed by a number of data bits. The
bit length of chunks is divisible by 8 - i.e. all chunks are byte aligned. All
values encoded in these data bits have the most significant bit on the left.
The 8-bit tags have precedence over the 2-bit tags. A decoder must check for the
presence of an 8-bit tag first.
The byte stream's end is marked with 7 0x00 bytes followed a single 0x01 byte.
The possible chunks are:
.- QOI_OP_INDEX ----------.
| Byte[0] |
| 7 6 5 4 3 2 1 0 |
|-------+-----------------|
| 0 0 | index |
`-------------------------`
2-bit tag b00
6-bit index into the color index array: 0..63
A valid encoder must not issue 2 or more consecutive QOI_OP_INDEX chunks to the
same index. QOI_OP_RUN should be used instead.
.- QOI_OP_DIFF -----------.
| Byte[0] |
| 7 6 5 4 3 2 1 0 |
|-------+-----+-----+-----|
| 0 1 | dr | dg | db |
`-------------------------`
2-bit tag b01
2-bit red channel difference from the previous pixel between -2..1
2-bit green channel difference from the previous pixel between -2..1
2-bit blue channel difference from the previous pixel between -2..1
The difference to the current channel values are using a wraparound operation,
so "1 - 2" will result in 255, while "255 + 1" will result in 0.
Values are stored as unsigned integers with a bias of 2. E.g. -2 is stored as
0 (b00). 1 is stored as 3 (b11).
The alpha value remains unchanged from the previous pixel.
.- QOI_OP_LUMA -------------------------------------.
| Byte[0] | Byte[1] |
| 7 6 5 4 3 2 1 0 | 7 6 5 4 3 2 1 0 |
|-------+-----------------+-------------+-----------|
| 1 0 | green diff | dr - dg | db - dg |
`---------------------------------------------------`
2-bit tag b10
6-bit green channel difference from the previous pixel -32..31
4-bit red channel difference minus green channel difference -8..7
4-bit blue channel difference minus green channel difference -8..7
The green channel is used to indicate the general direction of change and is
encoded in 6 bits. The red and blue channels (dr and db) base their diffs off
of the green channel difference and are encoded in 4 bits. I.e.:
dr_dg = (cur_px.r - prev_px.r) - (cur_px.g - prev_px.g)
db_dg = (cur_px.b - prev_px.b) - (cur_px.g - prev_px.g)
The difference to the current channel values are using a wraparound operation,
so "10 - 13" will result in 253, while "250 + 7" will result in 1.
Values are stored as unsigned integers with a bias of 32 for the green channel
and a bias of 8 for the red and blue channel.
The alpha value remains unchanged from the previous pixel.
.- QOI_OP_RUN ------------.
| Byte[0] |
| 7 6 5 4 3 2 1 0 |
|-------+-----------------|
| 1 1 | run |
`-------------------------`
2-bit tag b11
6-bit run-length repeating the previous pixel: 1..62
The run-length is stored with a bias of -1. Note that the run-lengths 63 and 64
(b111110 and b111111) are illegal as they are occupied by the QOI_OP_RGB and
QOI_OP_RGBA tags.
.- QOI_OP_RGB ------------------------------------------.
| Byte[0] | Byte[1] | Byte[2] | Byte[3] |
| 7 6 5 4 3 2 1 0 | 7 .. 0 | 7 .. 0 | 7 .. 0 |
|-------------------------+---------+---------+---------|
| 1 1 1 1 1 1 1 0 | red | green | blue |
`-------------------------------------------------------`
8-bit tag b11111110
8-bit red channel value
8-bit green channel value
8-bit blue channel value
The alpha value remains unchanged from the previous pixel.
.- QOI_OP_RGBA ---------------------------------------------------.
| Byte[0] | Byte[1] | Byte[2] | Byte[3] | Byte[4] |
| 7 6 5 4 3 2 1 0 | 7 .. 0 | 7 .. 0 | 7 .. 0 | 7 .. 0 |
|-------------------------+---------+---------+---------+---------|
| 1 1 1 1 1 1 1 1 | red | green | blue | alpha |
`-----------------------------------------------------------------`
8-bit tag b11111111
8-bit red channel value
8-bit green channel value
8-bit blue channel value
8-bit alpha channel value

// stb_c_lexer.h - v0.12 - public domain Sean Barrett 2013
// lexer for making little C-like languages with recursive-descent parsers
//
// This file provides both the interface and the implementation.
// To instantiate the implementation,
// #define STB_C_LEXER_IMPLEMENTATION
// in *ONE* source file, before #including this file.
//
// The default configuration is fairly close to a C lexer, although
// suffixes on integer constants are not handled (you can override this).
//
// History:
// 0.12 fix compilation bug for NUL support; better support separate inclusion
// 0.11 fix clang static analysis warning
// 0.10 fix warnings
// 0.09 hex floats, no-stdlib fixes
// 0.08 fix bad pointer comparison
// 0.07 fix mishandling of hexadecimal constants parsed by strtol
// 0.06 fix missing next character after ending quote mark (Andreas Fredriksson)
// 0.05 refixed get_location because github version had lost the fix
// 0.04 fix octal parsing bug
// 0.03 added STB_C_LEX_DISCARD_PREPROCESSOR option
// refactor API to simplify (only one struct instead of two)
// change literal enum names to have 'lit' at the end
// 0.02 first public release
//
// Status:
// - haven't tested compiling as C++
// - haven't tested the float parsing path
// - haven't tested the non-default-config paths (e.g. non-stdlib)
// - only tested default-config paths by eyeballing output of self-parse
//
// - haven't implemented multiline strings
// - haven't implemented octal/hex character constants
// - haven't implemented support for unicode CLEX_char
// - need to expand error reporting so you don't just get "CLEX_parse_error"
//
