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 1.6 - 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 any more
- Aligned data support
- Made support/compilation of the utility functions (ReportHash
and HashFile) optional (useful, if 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)
======== Test Vectors (from FIPS PUB 180-1) ========

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 1.6 - 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 any more
- Aligned data support
- Made support/compilation of the utility functions (ReportHash
and HashFile) optional (useful, if bytes count, for example in
embedded environments)
Version 1.9 - 2011-11-10
- Added Unicode test vectors.
- Improved support for hashing files using the HashFile method that
are larger than 4 GB.
- Improved file hashing performance (by using a larger buffer).
- Disabled unnecessary compiler warnings.
- Internal variables are now private.
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 1.8 - 2009-03-16
- 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.
======== Test Vectors (from FIPS PUB 180-1) ========
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 1.5 - 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).
SHA1(A million repetitions of "a") =
34AA973C D4C4DAA4 F61EEB2B DBAD2731 6534016F
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.
