In Cryptography, What are the advantages of using a PRNG over an RNG? What are the advantages of using an RNG over a PRNG?

Solution

PRNG:

Pseudorandom number generators are not random number generators at all. These generators typically use cryptographic algorithms (e.g., block ciphers or hash functions) to process a input value from the RNG into many random looking and unpredictable bytes.

PRNGs are most important in applications such as simulations , electronic games , and cryptography.

RNG:

A random number generator is a device that produces sequences of numbers. Two main classes of generators are present software and physical generators. software generators produce pseudo random numbers. Although they may be useful in some applications, they should not be used in most applications where randomness is required.
