Obviously, more than that, you can find a description from the StackOverflow link that explains why the JDK uses/dev/urandom, but it doesn't work. Random number generator, based on SHA1PRNG. And SHA1PRNG relies heavily on high-quality seeds, and if the seeds are not good enough, the results of random numbers can be predicted. So developers need to ma
