34d9477962SSam Leffler.Sh SYNOPSIS
35bc9a9cb4SRuslan Ermilov.Cd "device rndtest"
36d9477962SSam Leffler.Sh DESCRIPTION
37d9477962SSam LefflerThe
38d9477962SSam Leffler.Nm
39bc9a9cb4SRuslan Ermilovdriver
40bc9a9cb4SRuslan Ermilov.Dq "hooks up"
41bc9a9cb4SRuslan Ermilovto hardware crypto devices to monitor the
42d9477962SSam Lefflerentropy data passed to the
43d9477962SSam Leffler.Xr random 4
44d9477962SSam Lefflersubsystem.
45d9477962SSam LefflerThis data is periodically tested for FIPS 140-2 compliance and
46d9477962SSam Lefflerstatistics are collected.
47d9477962SSam LefflerIf the harvested entropy fails any of the FIPS test suite, then
48bc9a9cb4SRuslan Ermilovit is discarded and testing is continuously applied until
49bc9a9cb4SRuslan Ermilov.Dq "good data"
50d9477962SSam Leffleris received from the device.
51d9477962SSam LefflerFailures are optionally reported on the console.

58d9477962SSam Leffler.Sh HISTORY
59bc9a9cb4SRuslan ErmilovThe idea for this and the original code came from
60bc9a9cb4SRuslan Ermilov.An "Jason L. Wright" .
61d9477962SSam LefflerThe
62d9477962SSam Leffler.Nm
63d9477962SSam Lefflerdevice driver first appeared in
64d9477962SSam Leffler.Fx 5.0 .
65d9477962SSam Leffler.Sh BUGS
66d9477962SSam LefflerCrypto device drivers must be compiled specially to make use of this driver;
67d9477962SSam Lefflerthis should not be necessary.
68d9477962SSam LefflerThis feature might better be integrated into the
69d9477962SSam Leffler.Xr random 4
70d9477962SSam Lefflersubsystem where it can be used applied to devices that claim to supply
71bc9a9cb4SRuslan Ermilov.Dq "pure entropy" .
