Module Mirage_crypto_rng_lwt

RNG seeding on Lwt.

This module initializes a Fortuna RNG with getrandom(), and CPU RNG.

val initialize : ?⁠sleep:int64 -> unit -> unit

initialize ~sleep () will bring the RNG into a working state. The argument sleep is measured in ns (default 1s), and used to sleep between collection of entropy from the CPU RNG, every 10 * sleep getrandom is used to collect entropy.
