Specifications


The specifications for zlib and deflate were written by Peter Deutsch (Jean-loup co-authored the deflate spec), and Glenn Randers-Pehrson edited and submitted them to the Internet Engineering Task Force (IETF) as Internet Drafts. As of 22 May 1996, both have officially achieved RFC status. Variously formatted versions are available from many locations around the world, as is the related gzip specification (also written by Peter and also now an RFC).
