# JitterEntropyPort
Elixir wrapper for `jiterentropy-rngd` by @smuellerDD:
Using the Jitter RNG core, the rngd provides an entropy source that feeds
into the Linux /dev/random device if its entropy runs low. It updates
the /dev/random entropy estimator such that the newly provided entropy
unblocks /dev/random.
The seeding of /dev/random also ensures that /dev/urandom benefits from
entropy. Especially during boot time, when the entropy of Linux is low,
the Jitter RNGd provides a source of sufficient entropy.
Useful on embedded devices without a TRNG/PRNG support.
Requires the `jitter` module in the Linux kernel is loaded or compiled in.
More info here: https://www.chronox.de/jent/doc/CPU-Jitter-NPTRNG.html
## Kernel Config
Enable the jitter entropy module using menuconfig, or modify the Linux kernel config by setting:
```
CONFIG_CRYPTO_RNG=y
CONFIG_CRYPTO_JITTERENTROPY=y
```
If the `jitterentropy` needs loaded as a kernel module set in your config.exs:
config :jitter_entropy_port, :load_module, true
## Installation
If [available in Hex](https://hex.pm/docs/publish), the package can be installed
by adding `jitter_entropy_port` to your list of dependencies in `mix.exs`:
```elixir
def deps do
[
{:jitter_entropy_port, "~> 0.1.0"}
]
end
```
