few nitpicks on the code:
> int
> bin2hex (unsigned char *pcIbuf, unsigned char *pszObuf, unsigned int ilen)
> {
> unsigned int i; // loop iteration counter
> unsigned int j = (ilen * 2) + 1; // output buffer length
> unsigned char *p;
>
> p = pszObuf; // point to start of output buffer
^^^ given that you allow a MAXBUF input size, the worst case hexdump
output is 2*MAXBUF+1 which will overflow your obuf[] array, i.e.
corrupt stack.
> for (i = 0; i < ilen; i++) {
> sprintf_s (p, j, "%2.2x", (unsigned char) pcIbuf [i]);
You may try %02x as a format string instead; IIRC %2.2x does pad small
numbers with space instead of 0
