/* In order for the DH/DSA timing tests (which use cryptlib-internal
   mechanisms) to work, it's necessary to add the following lines of code to
   the start of cryptDeviceQueryCapability() in cryptapi.c, before any other
   code:

	if( cryptAlgo == 1000 )
		return( krnlSendMessage( device, IMESSAGE_SETATTRIBUTE_S,
								 cryptQueryInfo, CRYPT_IATTRIBUTE_KEY_SPKI ) );
	if( cryptAlgo == 1001 )
		return( krnlSendMessage( device, IMESSAGE_CTX_ENCRYPT,
								 cryptQueryInfo, sizeof( KEYAGREE_PARAMS ) ) );
	if( cryptAlgo == 1002 )
		return( krnlSendMessage( device, IMESSAGE_CTX_DECRYPT,
								 cryptQueryInfo, sizeof( KEYAGREE_PARAMS ) ) );
	if( cryptAlgo == 1003 )
		return( krnlSendMessage( device, IMESSAGE_CTX_SIGN,
								 cryptQueryInfo, sizeof( DLP_PARAMS ) ) );
	if( cryptAlgo == 1004 )
		return( krnlSendMessage( device, IMESSAGE_CTX_SIGCHECK,
								 cryptQueryInfo, sizeof( DLP_PARAMS ) ) );

   This is because the DH/DSA tests are handled by passing magic values into
   the function (which is very rarely used normally).  Remember to remove
   the magic-values check code after use!

   Under Unix, the test code can be built with:

	cc -c -D__UNIX__ testtime.c
	cc -o testtime -lpthread -lresolv testtime.o -L. -lcl

	1. Take the fastest time, which will be the time least affected by system

	2. Apply standard statistical techniques to weed out anomalies.  Since
