WebIf (when) I need to have, in Java, randomness which is good enough for formal cryptography (i.e. good, and also demonstrably good for regulatory purposes), then I use java.security.SecureRandom to generate an initial seed (at least 16 bytes), that I then run through HMAC_DRBG (specified in NIST SP800-90A)(the same publication contains the …

A pseudorandom number generator (PRNG), also known as a deterministic random bit generator (DRBG), is an algorithm for generating a sequence of numbers whose properties approximate the properties of sequences of random numbers. The PRNG-generated sequence is not truly random, because it is completely determined by an initial value, called the PRNG's seed (which may include truly random values). Although sequences that are closer to truly random can be generated using hardware …
