#3 Do not echo password in windows

[Brent]

Please change the code for keys.c to include the following change to readString. This prevents it from outputting the key to the console.

#ifdef WIN32
#include "conio.h"
#endif

int i=0;
while(i<MAXKEYBYTES)
{
iKeyBuffer[i] = getch();
if (iKeyBuffer[i] == 0xd ) // enter key
break;
i++;
}
iKeyBuffer[i] = (char)0;

Other than this change, the software is great. Keep up the good work.
