-100% free public domain implementation of the SHA-1 algorithm
-by Dominik Reichl <dominik.reichl@t-online.de>
-Web: http://www.dominik-reichl.de/
-
-Version 1.8 - 2008-03-16
-- Converted project files to Visual Studio 2008 format.
-- Added Unicode support for HashFile utility method.
-- Added support for hashing files using the HashFile method that are
-larger than 2 GB.
-- HashFile now returns an error code instead of copying an error
-message into the output buffer.
-- GetHash now returns an error code and validates the input parameter.
-- Added ReportHashStl STL utility method.
-- Added REPORT_HEX_SHORT reporting mode.
-- Improved Linux compatibility of test program.
-
-Version 1.7 - 2006-12-21
-- Fixed buffer underrun warning that appeared when compiling with
-Borland C Builder (thanks to Rex Bloom and Tim Gallagher for the
-patch).
-- Breaking change: ReportHash writes the final hash to the start
-of the buffer, i.e. it's not appending it to the string anymore.
-- Made some function parameters const.
-- Added Visual Studio 2005 project files to demo project.
-
-Version 1.6 - 2005-02-07 (thanks to Howard Kapustein for patches)
-- You can set the endianness in your files, no need to modify the
-header file of the CSHA1 class anymore.
-- Aligned data support.
-- Made support/compilation of the utility functions (ReportHash and
-HashFile) optional (useful when bytes count, for example in embedded
-environments).
-
-Version 1.5 - 2005-01-01
-- 64-bit compiler compatibility added.
-- Made variable wiping optional (define SHA1_WIPE_VARIABLES).
-- Removed unnecessary variable initializations.
-- ROL32 improvement for the Microsoft compiler (using _rotl).
-
-Version 1.4 - 2004-07-22
-- CSHA1 now compiles fine with GCC 3.3 under MacOS X  (thanks to Larry
-Hastings).
-
-Version 1.3 - 2003-08-17
-- Fixed a small memory bug and made a buffer array a class member to
-ensure correct working when using multiple CSHA1 class instances at
-one time.
-
-Version 1.2 - 2002-11-16
-- Borlands C++ compiler seems to have problems with string addition
-using sprintf. Fixed the bug which caused the digest report function
-not to work properly. CSHA1 is now Borland compatible.
-
-Version 1.1 - 2002-10-11
-- Removed two unnecessary header file includes and changed BOOL to
-bool. Fixed some minor bugs in the web page contents.
-
-Version 1.0 - 2002-06-20
-- First official release.
