Module Mirage_crypto_rng_unixSource
RNG seeding on Unix.
This module initializes a Fortuna RNG with getrandom(), and CPU RNG. On BSD systems (FreeBSD, OpenBSD, macOS) getentropy () is used instead of getrandom (). On Windows 10 or higher, BCryptGenRandom() is used with the default RNG. Windows 8 or lower are not supported by this library.
initialize ~g rng will bring the RNG into a working state.
getrandom size returns a buffer of size filled with random bytes.
A generator that opens /dev/urandom and reads from that file descriptor data whenever random data is needed. The file descriptor is closed in at_exit.
A generator using getrandom(3) on Linux, getentropy(3) on BSD and macOS, and BCryptGenRandom() on Windows.
use_default () initializes the RNG Mirage_crypto_rng.default_generator with a sensible default, at the moment using Getentropy.
use_dev_random () initializes the RNG Mirage_crypto_rng.default_generator with the Urandom generator. This raises an exception if "/dev/urandom" cannot be opened.
use_getentropy () initializes the RNG Mirage_crypto_rng.default_generator with the Getentropy generator.
