29.Dt RNDTEST 4
30.Os
31.Sh NAME
32.Nm rndtest
33.Nd FIPS 140-2 random number generator test monitor
34.Sh SYNOPSIS
35.Cd "device rndtest"
36.Sh DESCRIPTION
37The
38.Nm
39driver
40.Dq "hooks up"
41to hardware crypto devices to monitor the
42entropy data passed to the
43.Xr random 4
44subsystem.
45This data is periodically tested for FIPS 140-2 compliance and
46statistics are collected.
47If the harvested entropy fails any of the FIPS test suite, then
48it is discarded and testing is continuously applied until
49.Dq "good data"
50is received from the device.
51Failures are optionally reported on the console.
52.Sh SEE ALSO
53.Xr crypto 4 ,
54.Xr hifn 4 ,
55.Xr random 4 ,
56.Xr safe 4 ,
57.Xr ubsec 4 ,
58.Xr crypto 9
59.Sh HISTORY
60The idea for this and the original code came from
61.An "Jason L. Wright" .
62The
63.Nm
64device driver first appeared in
65.Fx 5.0 .
66.Sh BUGS
67Crypto device drivers must be compiled specially to make use of this driver;
68this should not be necessary.
69This feature might better be integrated into the
70.Xr random 4
71subsystem where it can be applied to devices that claim to supply
72.Dq "pure entropy" .
