Authors of XZ Utils =================== XZ Utils is developed and maintained by Lasse Collin and Jia Tan . Major parts of liblzma are based on code written by Igor Pavlov, specifically the LZMA SDK . Without this code, XZ Utils wouldn't exist. The SHA-256 implementation in liblzma is based on code written by Wei Dai in Crypto++ Library . A few scripts have been adapted from GNU gzip. The original versions were written by Jean-loup Gailly, Charles Levert, and Paul Eggert. Andrew Dudman helped adapting the scripts and their man pages for XZ Utils. The initial version of the threaded .xz decompressor was written by Sebastian Andrzej Siewior. The initial version of the .lz (lzip) decoder was written by Michał Górny. Architecture-specific CRC optimizations were contributed by Ilya Kurdyukov, Hans Jansen, and Chenxi Mao.
