- class jacdac.rng.RngClient(bus: jacdac.bus.Bus, role: str)
Bases:
jacdac.bus.Client- Generates random numbers using entropy sourced from physical processes.
This typically uses a cryptographical pseudo-random number generator (for example [Fortuna](<https://en.wikipedia.org/wiki/Fortuna_(PRNG)>)),
which is periodically re-seeded with entropy coming from some hardware source.
Implements a client for the Random Number Generator service.
- property random: bytes | None
A register that returns a 64 bytes random buffer on every request. This never blocks for a long time. If you need additional random bytes, keep querying the register.,
- property variant: jacdac.rng.constants.RngVariant | None
(Optional) The type of algorithm/technique used to generate the number. Quantum refers to dedicated hardware device generating random noise due to quantum effects. ADCNoise is the noise from quick readings of analog-digital converter, which reads temperature of the MCU or some floating pin. WebCrypto refers is used in simulators, where the source of randomness comes from an advanced operating system.,
