Package io.github.pr0methean.betterrandom.seed

Tools to obtain and apply truly-random seeds for Random implementations, especially those that also implement ByteArrayReseedableRandom.

Interface Summary

Interface	Description
SeedGenerator	Strategy interface for seeding random number generators.

Class Summary

Class	Description
AnuQuantumSeedClient	API client for the Australian National University's quantum RNG, which extracts randomness from quantum-vacuum fluctuations.
BufferedSeedGenerator	A seed generator that wraps another, maintaining a buffer of previously-fetched bytes to reduce the number of I/O calls.
LegacyRandomSeeder	A RandomSeeder that can reseed any instance of Random.
RandomDotOrgAnonymousClient	Connects to random.org's old API (via HTTPS) and downloads a set of random bits to use as seed data.
RandomDotOrgApi2Client	Uses the random.org JSON API documented at api.random.org.
RandomSeeder	Thread that loops over ByteArrayReseedableRandom instances and reseeds them.
RandomSeeder.DefaultThreadFactory	A ThreadFactory that sets the name and priority of the threads it creates.
SecureRandomSeedGenerator	SeedGenerator implementation that uses Java's bundled SecureRandom RNG to generate random seed data.
SeedGeneratorPreferenceList	A SeedGenerator implementation that iterates over multiple delegates until one succeeds.
SeedGeneratorPreferenceList.Builder
WebSeedClient	A SeedGenerator that is a client for a Web random-number service.
WebSeedClientConfiguration	Common configuration parameters for an instance of WebSeedClient.
WebSeedClientConfiguration.Builder

Enum Summary

Enum	Description
DefaultSeedGenerator	Seed generator that is the default for the program where it is running.
DevRandomSeedGenerator	RNG seed strategy that gets data from /dev/random on systems that provide it (e.g.

Exception Summary

Exception	Description
SeedException	Exception thrown by SeedGenerator implementations when they are unable to generate a new seed for an RNG.
