|
||||
|
||||
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'
