.SH DESCRIPTION
.B infnoise
provides access to the Infinite Noise True Random Number Generator and
allows the data it generates to be fed into the system's random number
generator.
.PP
.B infnoise \-\-help
shows a short summary of the options.
.PP
.B infnoise \-\-version
displays the program's version information.
.PP
.B infnoise \-\-list\-devices
lists all the supported TRNG devices present on the system.
.PP
.B infnoise
reads random data from a TRNG and outputs filtered random data to its
standard output. The various options control the program's behaviour.
.SH OPTIONS
.TP
.B \-\-debug
measures the quality of the data obtained from the TRNG. It is
typically used with \-\-no\-output as a sanity test.
.TP
.B \-\-dev\-random
adds the filtered data to the system's entropy pool instead of sending
it to its standard output.
.TP
.B \-\-raw
disables output whitening.
.TP
.BR \-\-multiplier <\fIvalue\fP>
writes 256 bits ×
.I value
for every 512 bits written to the Keccak sponge; the default of 0
means to write all the available entropy, without multiplying it.
.TP
.B \-\-no\-output
disables output of random data.
.TP
.BR \-\-pidfile <\fIfile\fP>
stores the process' identifier in
.IR file .
.TP
.B \-\-daemon
starts the program as a daemon.
.TP
.BR \-\-serial <\fIserial\fP>
uses the device matching the specified
.IR serial .
