SecureRandom class abstract
A synchronous secure random number generator (RNG).
Being synchronous, this RNG cannot return direct results from sources of randomness like '/dev/random' or similar. For that, use an EntropySource which allows to be called asynchronously. Usually an EntropySource should be seen like a random generation device while a SecureRandom should be seen like a cryptographic PRNG. Thus, data from an EntropySource should be seen as 'more random' than that returned from a SecureRandom.
