In cryptography, a pseudo-random generator (PRG) is a deterministic procedure that maps a random seed to a longer pseudo-random string such that no statistical test can distinguish between the output of the generator and the uniform distribution. Pseudo-random generators have numerous applications in cryptography. For instance, pseudo-random generators provide an efficient analog of one-time pads.

How can we know how good a TRNG is?
Imagine that a perfect TRNG generates 100 bits, which are then fed into a high quality PRNG such as ChaCha20, which generates 1000 bits.
How many bits of entropy is in the 1000 bits? Depends on who is …
