module Netsys_rng

: sig

Random-number generator

This is an interface to an OS-provided RNG that is fast and nevertheless secure enough for creating session keys. Note that it should not be used for creating long-term keys.

On Unix, the /dev/urandom device is used. If it is not available, the functions fail.

On Win32, an RNG is obtained using CryptAcquireContext.

val set_rng : (string -> unit) -> unit

Sets the globally used RNG

val fill_random : string -> unit

Fills this string with random bytes

end
