32d9477962SSam Leffler.Sh SYNOPSIS
33bc9a9cb4SRuslan Ermilov.Cd "device rndtest"
34d9477962SSam Leffler.Sh DESCRIPTION
35d9477962SSam LefflerThe
36d9477962SSam Leffler.Nm
37bc9a9cb4SRuslan Ermilovdriver
38bc9a9cb4SRuslan Ermilov.Dq "hooks up"
39bc9a9cb4SRuslan Ermilovto hardware crypto devices to monitor the
40d9477962SSam Lefflerentropy data passed to the
41d9477962SSam Leffler.Xr random 4
42d9477962SSam Lefflersubsystem.
43d9477962SSam LefflerThis data is periodically tested for FIPS 140-2 compliance and
44d9477962SSam Lefflerstatistics are collected.
45d9477962SSam LefflerIf the harvested entropy fails any of the FIPS test suite, then
46bc9a9cb4SRuslan Ermilovit is discarded and testing is continuously applied until
47bc9a9cb4SRuslan Ermilov.Dq "good data"
48d9477962SSam Leffleris received from the device.
49d9477962SSam LefflerFailures are optionally reported on the console.

56d9477962SSam Leffler.Sh HISTORY
57bc9a9cb4SRuslan ErmilovThe idea for this and the original code came from
58bc9a9cb4SRuslan Ermilov.An "Jason L. Wright" .
59d9477962SSam LefflerThe
60d9477962SSam Leffler.Nm
61d9477962SSam Lefflerdevice driver first appeared in
62d9477962SSam Leffler.Fx 5.0 .
63d9477962SSam Leffler.Sh BUGS
64d9477962SSam LefflerCrypto device drivers must be compiled specially to make use of this driver;
65d9477962SSam Lefflerthis should not be necessary.
66d9477962SSam LefflerThis feature might better be integrated into the
67d9477962SSam Leffler.Xr random 4
6803cfc716SChristian Brueffersubsystem where it can be applied to devices that claim to supply
69bc9a9cb4SRuslan Ermilov.Dq "pure entropy" .
