+
+Corrected a problem which generated improper hash values on 16 bit machines
+Routine SHA1Update changed from
+	void SHA1Update(SHA1_CTX* context, unsigned char* data, unsigned int
+len)
+to
+	void SHA1Update(SHA1_CTX* context, unsigned char* data, unsigned
+long len)
+
+The 'len' parameter was declared an int which works fine on 32 bit machines.
+However, on 16 bit machines an int is too small for the shifts being done
+against
+it.  This caused the hash function to generate incorrect values if len was
+greater than 8191 (8K - 1) due to the 'len << 3' on line 3 of SHA1Update().
+
+Since the file IO in main() reads 16K at a time, any file 8K or larger would
+be guaranteed to generate the wrong hash (e.g. Test Vector #3, a million
+"a"s).
+
+I also changed the declaration of variables i & j in SHA1Update to 
+unsigned long from unsigned int for the same reason.
+
+These changes should make no difference to any 32 bit implementations since
+an
+int and a long are the same size in those environments.
+
+--
+I also corrected a few compiler warnings generated by Borland C.
+1. Added #include <process.h> for exit() prototype
+2. Removed unused variable 'j' in SHA1Final
+3. Changed exit(0) to return(0) at end of main.
+
+ALL changes I made can be located by searching for comments containing 'JHB'
+-----------------
+Modified 8/98
+By Steve Reid <sreid@sea-to-sky.net>
+Still 100% public domain
+
+1- Removed #include <process.h> and used return() instead of exit()
+2- Fixed overwriting of finalcount in SHA1Final() (discovered by Chris Hall)
+3- Changed email address from steve@edmweb.com to sreid@sea-to-sky.net
+
+-----------------
+Modified 4/01
+By Saul Kravitz <Saul.Kravitz@celera.com>
+Still 100% PD
+Modified to run on Compaq Alpha hardware.  
+
+-----------------
+Modified 4/01
+By Jouni Malinen <j@w1.fi>
+Minor changes to match the coding style used in Dynamics.
+
+Modified September 24, 2004
+By Jouni Malinen <j@w1.fi>
+Fixed alignment issue in SHA1Transform when SHA1HANDSOFF is defined.
