WebCryptographic algorithms require keys. A Random Number Generator (RNG), also called a Random Bit Generator (RBG), is needed in the key generation process to create a random (strong) key as well as for other cryptographic purposes … WebCompare this to Alice generating a 20 digit pseudorandom sequence, using a four-digit random seed. Now, this is equivalent to a uniform selection from 10,000 possible initial seeds, meaning she can only generate 10,000 different sequences, which is a vanishingly small fraction of all possible sequences.
