rndtest — FIPS 140-2 random number generator test monitor

       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”.

Debian                                           March 11, 2003                                       RNDTEST(4)

       The  rndtest  driver  “hooks  up”  to  hardware  crypto devices to monitor the entropy data passed to the
       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.

       The  idea  for  this  and  the  original code came from Jason L. Wright.  The rndtest device driver first
       appeared in FreeBSD 5.0.
