.Sh NAME
|
|
.Nm rndtest
|
|
.Nd FIPS 140-2 random number generator test monitor
|
|
.Sh SYNOPSIS
|
|
.Cd device rndtest
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver ``hooks up'' to hardware crypto devices to monitor the
|
|
entropy data passed to the
|
|
.Xr random 4
|
|
subsystem.
|
|
This data is periodically 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.

|
|
.Sh HISTORY
|
|
The idea for this and the original code came from Jason L. Wright.
|
|
The
|
|
.Nm
|
|
device driver first appeared in
|
|
.Fx 5.0 .
|
|
.Sh 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
|
|
.Xr random 4
|
|
subsystem where it can be used applied to devices that claim to supply
|
|
``pure entropy''.
