module Nocrypto_entropy_unix:sig..end
This module provides one-shot RNG seeding from the Unix kernel RNG, typically
/dev/urandomCalling initialize is enough to bring the RNG into a working state.
initialize is idempotent as long as the default generator is unchanged.
It is harmless to call it several times.
If you are using lwt, conside using Nocrypto_entropy_lwt as this
module allows for continuous reseeding.
Unless you want to recover from an unlikely case of missing system RNG, the
recommended way to prime the RNG is to invoke initialize at the module
level:
let () = Nocrypto_entropy_unix.initialize () val initialize : unit -> unit
This is the closest thing to Random.self_init and is a good way to prime
the RNG.
val sys_rng : stringval reseed : ?bytes:int -> ?device:string -> Nocrypto.Rng.g -> unitreseed ~bytes ~g mixes in bytes bytes from the system RNG into the
generator g.
bytes default to a small value reasonable for periodic reseeding.
device defaults to sys_rng.
