WebNov 6, 2024 · The Java Random class is a Pseudo-Random Number Generator (PRNG), also known as Deterministic Random Number Generator (DRNG). This means it's not truly random. The sequence of random numbers in a PRNG can be completely determined based on its seed.

WebFeb 24, 2024 · Cryptographic Hash is a Hash function that takes random size input and yields a fixed-size output. It is easy to calculate but challenging to retrieve the original data. It is strong and difficult to duplicate the same hash with unique inputs and is a one-way function so revert is not possible.
