devr-file.so

Updated: April 19, 2023

Random service entropy library for path-based entropy sources

Syntax:

random -l devr-file.so:path=path,[option[,option ...]]

Runs on:

QNX Neutrino

Options:

delay=seconds
Provide entropy to the random service at this interval, in seconds. (Range 1-300s, default 15s).
prio=priority
The minimum priority for the entropy collection thread.
path=path
Path to the entropy source.
entropy=entropy_bytes
Number of bytes to read from the path and provide to the random service.

Description:

The devr-file.so shared object reads entropy from a file. Although the file is usually managed by a resource manager for a hardware random number generator, it can also be a large file with random values in it.

Examples:

random -l devr-file.so:path=/dev/hwrng
