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
void SHA1Update(P_SHA1_CTX* context, unsigned char* data, unsigned int
len)
to
void SHA1Update(SHA1_CTX* context, unsigned char* data, unsigned
void SHA1Update(P_SHA1_CTX* context, unsigned char* data, unsigned
long len)
The 'len' parameter was declared an int which works fine on 32 bit machines.
