1 ACKNOWLEDGMENTS 2 3* We used "Screaming Fast Galois Field Arithmetic Using Intel 4 SIMD Instructions" paper by James S. Plank, Kevin M. Greenan 5 and Ethan L. Miller to improve Reed-Solomon coding performance. 6 Also we are grateful to Artem Drobanov and Bulat Ziganshin 7 for samples and ideas allowed to make Reed-Solomon coding 8 more efficient. 9 10* RAR text compression algorithm is based on Dmitry Shkarin PPMII 11 and Dmitry Subbotin carryless rangecoder public domain source code. 12 You may find it in ftp.elf.stuba.sk/pub/pc/pack. 13 14* RAR encryption includes parts of code from Szymon Stefanek 15 and Brian Gladman AES implementations also as Steve Reid SHA-1 source. 16 17 --------------------------------------------------------------------------- 18 Copyright (c) 2002, Dr Brian Gladman < >, Worcester, UK. 19 All rights reserved. 20 21 LICENSE TERMS 22 23 The free distribution and use of this software in both source and binary 24 form is allowed (with or without changes) provided that: 25 26 1. distributions of this source code include the above copyright 27 notice, this list of conditions and the following disclaimer; 28 29 2. distributions in binary form include the above copyright 30 notice, this list of conditions and the following disclaimer 31 in the documentation and/or other associated materials; 32 33 3. the copyright holder's name is not used to endorse products 34 built using this software without specific written permission. 35 36 ALTERNATIVELY, provided that this notice is retained in full, this product 37 may be distributed under the terms of the GNU General Public License (GPL), 38 in which case the provisions of the GPL apply INSTEAD OF those given above. 39 40 DISCLAIMER 41 42 This software is provided 'as is' with no explicit or implied warranties 43 in respect of its properties, including, but not limited to, correctness 44 and/or fitness for purpose. 45 --------------------------------------------------------------------------- 46 47 Source code of this package also as other cryptographic technology 48 and computing project related links are available on Brian Gladman's 49 web site: http://www.gladman.me.uk 50 51* RAR uses CRC32 function based on Intel Slicing-by-8 algorithm. 52 Original Intel Slicing-by-8 code is available here: 53 54 https://sourceforge.net/projects/slicing-by-8/ 55 56 Original Intel Slicing-by-8 code is licensed under BSD License 57 available at http://www.opensource.org/licenses/bsd-license.html 58 59 Copyright (c) 2004-2006 Intel Corporation. 60 All Rights Reserved 61 62 Redistribution and use in source and binary forms, with or without 63 modification, are permitted provided that the following conditions 64 are met: 65 66 Redistributions of source code must retain the above copyright notice, 67 this list of conditions and the following disclaimer. 68 69 Redistributions in binary form must reproduce the above copyright 70 notice, this list of conditions and the following disclaimer 71 in the documentation and/or other materials provided with 72 the distribution. 73 74 THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS 75 "AS IS" AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT 76 LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS 77 FOR A PARTICULAR PURPOSE ARE DISCLAIMED.
