+ 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)
+
