Compression library based on the algorithm used in aPACK. Includes both 32-bit and 64-bit libraries, and source code for decompression in C and asm.

Registration key system which uses public-key cryptography to produce a signature protecting the registration information. This is a demo version.

16-bit DOS executable compressor. aPACK compresses the file while keeping it executable. aPACK uses advanced compression heuristics and tricks to achieve the best compression ratio. aPACK has ranked as one of the best 16-bit DOS executable packers for years.

BriefLZ is a small and fast open source implementation of a Lempel-Ziv style compression algorithm. The main focus is on speed and code footprint, but the ratios achieved are quite good compared to similar algorithms.

tinf is a small library implementing the decompression algorithm for the deflate compressed data format (called 'inflate'). Deflate compression is used in e.g. zlib, gzip, zip, and png.

aPackage is a simple sfx archiver for Windows, developed as an alternative to the well-known archive formats (zip, rar). aPackage uses the aPLib compression library to produce tight self-extracting archives while maintaining a small stub size and fast extraction speed.

A simple byte-patch generator. Can create fast multi-file patches with search/replace from simple scripts, with optional backup creation and CRC checking. Output is a Win32 GUI executable.

A little utility to cut out parts of a file and save them as binary data or C / asm includable data. File offsets can be given in dec, hex or oct. C-source included.

WCRT is a small C runtime library for Visual C++, which implements parts of its functionality through calls to the Win32API. It is meant as a replacement for the Visual C runtime library (libc.lib) when creating small statically linked executables.
