## README



The repository does not contain a README file or any similar documentation file. The structure and code files suggest that this is a technical implementation of compression and decompression algorithms, including LZMA, XZ, and others, along with cryptographic functions like AES and SHA-256.

If you need assistance generating a README based on specific files or functions, please specify which components you want to highlight or any particular use case for the README. Otherwise, here is a basic README template tailored to the inferred purpose of the project:

# 7-Zip Compression Library

This repository contains low-level implementations of various compression, decompression, and cryptographic hashing algorithms used in the 7-Zip project. It includes support for LZMA, LZMA2, BCJ2, PPMD, and other coders, along with hash functions such as SHA-256 and CRC64.

## Features

- **Compression Algorithms**: LZMA, LZMA2, PPMD, Delta encoding.
- **Decompression**: Support for decoding LZMA, LZMA2, and XZ formats.
- **Cryptographic Hashing**: SHA-256, CRC64.
- **Optimized Assembly Code**: Architecture-specific assembly files for performance-critical operations on x86, ARM, and ARM64.
- **Multi-threading Support**: Files related to multi-threaded compression and decompression.

## Usage

This codebase is intended for developers who need to integrate or extend the 7-Zip compression algorithms or hashing functions in their applications. It provides APIs for:
- Compressing and decompressing data.
- Hashing data for integrity verification.
- Managing file and stream operations.

## Building

The build system supports various compilers and platforms. Makefiles and project files are provided for:
- GCC
- Clang
- Microsoft Visual Studio

### Requirements

- A C/C++ compiler.
- Make (for GCC/Clang builds).
- Windows SDK (for Windows builds).

### Build Instructions

For GCC/Clang:
```bash
make -f makefile.gcc
```

For Visual Studio:
Open the `.dsp` or `.dsw` files in the appropriate directory and build.

## Contributing

If you are interested in contributing, ensure you are familiar with the codebase and the 7-Zip SDK. Contributions should align with the goals of the 7-Zip project and maintain performance and clarity.

## License

The code is licensed under the GNU LGPL, along with some files under different open-source licenses. Please check individual files for specific license information.

## Contact
