WebPseudo-Random Number Generators (PRNG) provide low-quality randomness that are much faster, and can be used for non-security related functionality (such as ordering results on … WebBecause Random.nextInt() is a statistical PRNG, it is easy for an attacker to guess the strings it generates. Although the underlying design of the receipt system is also faulty, it would be more secure if it used a random number generator that did not produce predictable receipt identifiers, such as a cryptographic PRNG.
