7-Zip

An open source utility that provides fast incremental file transfer. It also has useful features for backup and restore operations among many other use cases.

zsync - rsync over http

Base on libdeflate, added support compress & decompress by stream, and added base API for support parallel compress. And at the same time, try to keep it simple and fast. See programs/pgzip.c, a de…

Base on zstd, added delta update dict API for hsynz.

Extremely fast non-cryptographic hash algorithm

hsynz is a library for delta update using sync algorithm, like zsync. rsync over http(s); implement the sync algorithm on client side, and server side only need http(s) cdn. support compressor zstd…

msufsort parallel suffix array construction algorithm

Lite version of HDiffPatch, tiny code & ram requires when patch on embedded systems,MCU,NB-IoT,...

The libsais library provides fast linear-time construction of suffix array (SA), generalized suffix array (GSA), longest common prefix (LCP) array, permuted LCP (PLCP) array, Burrows-Wheeler transf…

An encoder/decoder for the VCDIFF (RFC3284) format

a C\C++ library and command-line tools for Diff & Patch between binary files or directories(folder); cross-platform; runs fast; create small delta/differential; support large files and limit memory…

tiny code & ram requires when decompress on embedded systems,MCU,NB-IoT,...

Brotli compression format

Heavily optimized library for DEFLATE/zlib/gzip compression and decompression

Fast, small, in-memory inflate (zlib, deflate and gzip decompression)

Precomp, C++ version - further compress already compressed files

Zstandard - Fast real-time compression algorithm

stable & fast to patch apk archives, used by Android app store. 为安卓应用商店使用而优化的apk增量更新算法。

a C++ library and command-line tools for Zip(Jar,Apk) file Diff & Patch; create minimal delta/differential; support Jar sign(apk v1 sign) & apk v2,v3,v4 sign .

A minimal 2-file (cpp+h) TCP & HTTP client implementation. Supports GET & simple POST. Optional SSL via PolarSSL/mbedTLS. Cross-platform, uses POSIX or Win32 API. C++03 with STL.

Delphi泛型库--DGL(The Delphi Generic Library)

这是Unity Android APP il2cpp热更完美解决方案的Demo。更新build_demo_apk里的Unity路径，执行即可一键重build Patch和apk。因为文件libunity是没有热更的，如unity版本有变化则热更不适用。

bsdiff and bspatch are libraries for building and applying patches to binary files.
