Webb20 okt. 2024 · 1 Answer Sorted by: 2 In most cases your runtime uses a DRBG rather than a PRNG. A DRBG is a Deterministic Random Bit Generator, so it delivers bits to the user rather than random numbers in a specific range. Generally it is possible to request bytes and then use - for instance - the lowest 4 bits.
