zlib

The zlib is a free library for compressing and decompressing data with the Deflate algorithm.

Technology

Zlib can create both gzip files (. gz) as also edit a data stream. The format of the output data stream, the Deflate algorithm and the gzip file format were standardized as RFC 1950, RFC 1951 and RFC 1952. zlib is data blocks from. The output blocks are protected by Adler -32 checksums.

History

The program library is by Jean- Loup Gailly ( compression) and Mark Adler (decompression), the authors of gzip and other known data compression programs. It was originally created for the libpng reference library for the Deflate compression in PNG format. The first public version 0.9 was released on 1 May 1995. (Acquired zlib license, approved by the OSI and for numerous other projects) In addition to the program introduced by the Free Software license was also made sure not to use any patented algorithms.

The small, efficient and versatile library has established itself especially among Linux as the de facto standard for deflate (de-) compression is used by hundreds of programs and is popular because of their relatively low memory consumption for embedded systems.
