"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. " - Cryptographic prng in java
