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 peri-
     odically tested for FIPS 140-2 compliance and statistics are collected.  If the harvested entropy fails any of the FIPS test suite, then it
     is discarded 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
     integrated into the random(4) subsystem where it can be applied to devices that claim to supply ``pure entropy''.
