Introduction

This site is a part of bsc and libbsc, a program and a library for lossless data compression. bsc is a high performance file compressor based on lossless, block-sorting data compression algorithms. libbsc is a library based on bsc, it uses the same algorithms as bsc and enables you to compress memory blocks.

Features
