From 76946dc4336c831fe2cc26696a035d807dd3cf13 Mon Sep 17 00:00:00 2001 From: Lasse Collin Date: Fri, 9 Feb 2024 17:20:31 +0200 Subject: Fix SHA-256 authors. The initial commit 5d018dc03549c1ee4958364712fb0c94e1bf2741 in 2007 had a comment in sha256.c that the code is based on Crypto++ Library 5.5.1. In 2009 the Authors list in sha256.c and the AUTHORS file was updated with information that the code had come from Crypto++ but via 7-Zip. I know I had viewed 7-Zip's SHA-256 code but back then the C code has been identical enough with Crypto++, so I don't why I thought the author info would need that extra step via 7-Zip for this single file. Another error is that I had mixed sha.* and shacal2.* files when checking for author info in Crypto++. The shacal2.* files aren't related to liblzma's sha256.c and thus Kevin Springle's code in Crypto++ isn't either. --- src/liblzma/check/sha256.c | 14 ++++---------- 1 file changed, 4 insertions(+), 10 deletions(-) (limited to 'src/liblzma') diff --git a/src/liblzma/check/sha256.c b/src/liblzma/check/sha256.c index 6feb3425..9247fa32 100644 --- a/src/liblzma/check/sha256.c +++ b/src/liblzma/check/sha256.c @@ -2,18 +2,12 @@ // /// \file sha256.c /// \brief SHA-256 -/// -/// \todo Crypto++ has x86 ASM optimizations.
