"Fossies" - the Fresh Open Source Software Archive
Member "unrar/acknow.txt" (7 Oct 2021, 2780 Bytes) of package /linux/misc/unrarsrc-6.1.7.tar.gz:
As a special service "Fossies" has tried to format the requested text file into HTML format (style: standard
) with prefixed line numbers.
Alternatively you can here view
the uninterpreted source code file.
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.
10 * RAR4 text compression algorithm is based on Dmitry Shkarin PPMII
11 and Dmitry Subbotin carryless rangecoder public domain source code.
12 You can find it in ftp.elf.stuba.sk/pub/pc/pack.
14 * RAR encryption includes parts of public domain code
15 from Szymon Stefanek AES and Steve Reid SHA-1 implementations.
17 * With exception of SFX modules, RAR uses CRC32 function based
18 on Intel Slicing-by-8 algorithm. Original Intel Slicing-by-8 code
19 is available here:

54 * RAR archives may optionally include BLAKE2sp hash ( https://blake2.net ),
55 designed by Jean-Philippe Aumasson, Samuel Neves, Zooko Wilcox-O'Hearn
56 and Christian Winnerlein.
58 * Useful hints provided by Alexander Khoroshev and Bulat Ziganshin allowed
59 to significantly improve RAR compression and speed.
