Thankfully the C code making up the latest version is only 18K lines long and there have been ports to C++ which were a little over 3K lines long. Any security vulnerability in the library could have a significant global impact. The zlib library is considered to be one of the most widely distributed pieces of code in the world as it's used by a huge variety of software. The compression functionality of zlib was produced by Jean-loup Gailly and the decompression components were written by Mark Adler. In addition to ZIP files, DEFLATE has found use in GZIP and PNG files as well as the HTTP protocol.Īn open-source implementation of DEFLATE was included in zlib, which was first released in 1995. DEFLATE was defined by Phil Katz in 1989 and is a derivative of the LZ77 algorithm originally published twelve years prior to that. Though the popular ZIP archive file format supports multiple lossless data compression schemes, DEFLATE remains almost ubiquitous. Unfortunately, often when presented with a data feed those decisions have already been made on your behalf. Having a wide variety of compression formats means you can pick between various trade-offs.
