RNDTEST(4)		 BSD Kernel Interfaces Manual		    RNDTEST(4)

NAME
     rndtest --	FIPS 140-2 random number generator test	monitor

SYNOPSIS
     device rndtest

DESCRIPTION
     The rndtest driver	"hooks up" to hardware crypto devices to monitor the
     entropy data passed to the	random(4) subsystem.  This data	is periodi-
     cally tested for FIPS 140-2 compliance and	statistics are collected.  If
     the harvested entropy fails any of	the FIPS test suite, then it is	dis-
     carded and	testing	is continuously	applied	until "good data" is received
     from the device.  Failures	are optionally reported	on the console.

SEE ALSO
     crypto(4),	hifn(4), random(4), safe(4), ubsec(4), crypto(9)

HISTORY
     The idea for this and the original	code came from Jason L.	Wright.	 The
     rndtest device driver first appeared in FreeBSD 5.0.

BUGS
     Crypto device drivers must	be compiled specially to make use of this
     driver; this should not be	necessary.  This feature might better be inte-
     grated into the random(4) subsystem where it can be applied to devices
     that claim	to supply "pure	entropy".
