zlib 1.2.11 Manual

Jan 02, 2011·Those formats provide their own check values. If a custom format is developed using the raw deflate format for compressed data, it is recommended that a check value such as an Adler-32 or a CRC-32 be applied to the uncompressed data as is done in the zlib, gzip, and zip formats. For most applications, the zlib format should be used as is.

GZIP/ZLIB/Deflate Data Compression Core

ZipAccel-C is a custom hardware implementation of a lossless data compression engine that complies with the Deflate, GZIP, and ZLIB compression standards. The core receives uncompressed input files and produces compressed files. No post processing of the compressed files is required, as the core encapsulates the com-pressed data payload with the proper headers and footers.
