WebThe DRBG produces a sequence of bits from a secret initial value called a seed. A cryptographic DRBG has the additional property that the output is unpredictable given that the seed is not known. A DRBG is sometimes also called a pseudo-random number generator (PRNG) or a deterministic random number generator. WebSep 14, 2024 · In normal use the prng is opaque and its internal state cannot be accessed. However, if the "state" option is specified, the prng gets a state () method that returns a plain object the can be used to reconstruct a prng later in the same state (by passing that saved object back as the state option).
