11Corrected a problem which generated improper hash values on 16 bit machines
12Routine SHA1Update changed from
13 void SHA1Update(SHA1_CTX* context, unsigned char* data, unsigned int
14len)
15to
16 void SHA1Update(SHA1_CTX* context, unsigned char* data, unsigned
17long len)
18
19The 'len' parameter was declared an int which works fine on 32 bit machines.
20However, on 16 bit machines an int is too small for the shifts being done
21against
22it. This caused the hash function to generate incorrect values if len was
23greater than 8191 (8K - 1) due to the 'len << 3' on line 3 of SHA1Update().
24
25Since the file IO in main() reads 16K at a time, any file 8K or larger would
26be guaranteed to generate the wrong hash (e.g. Test Vector #3, a million
27"a"s).
28
29I also changed the declaration of variables i & j in SHA1Update to
30unsigned long from unsigned int for the same reason.
31
32These changes should make no difference to any 32 bit implementations since
33an
34int and a long are the same size in those environments.
35
36--
37I also corrected a few compiler warnings generated by Borland C.
381. Added #include <process.h> for exit() prototype
392. Removed unused variable 'j' in SHA1Final
403. Changed exit(0) to return(0) at end of main.

42ALL changes I made can be located by searching for comments containing 'JHB'

481- Removed #include <process.h> and used return() instead of exit()
492- Fixed overwriting of finalcount in SHA1Final() (discovered by Chris Hall)
