Brown <jbrown@burgoyne.com> +Still 100% Public Domain + +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.
