Linux Entropy Daemon

This repository hosts the code for a simple client application to seed the Linux kernel with entropy from a remote server via HTTP. It attempts to adhere to the UNIX philosophy of doing one thing and doing it well.

Build

To compile the code execute the following in a terminal. This will produce three entropyd binaries for the arm, arm64 and amd64 architectures in different directories under bin.

make clean && make build

Usage

Usage of entropyd:
  -dry-run
        makes a request for 512 bits of entropy but does not mix in to the kernel entropy pool
  -max int
        maximum amount of entropy (in bits) in a HTTP request (default 8192)
  -min int
        minimum amount of entropy (in bits) in a HTTP request (default 512)
  -poll int
        interval (in milliseconds) at which to poll the kernel entropy pool (default 200)
  -url string
        URL of the remote entropy server (default "https://entropy.malc.org.uk/entropy/")
