Method Detail

clear

public void clear()

Description copied from class: RandomBitsSource

Clears out sensitive data pools within the PRNG. Note that in so doing, the PRNG may be brought to an unusable state (e.g. requiring new seed material). Implementing classes should throw an exception when random bytes are request in this case.

Specified by:

clear in class RandomBitsSource

randomBytes

public byte[] randomBytes(byte[] bytes)

Fill a byte array with random bytes.

Overrides:

randomBytes in class RandomBitsSource

randomByte

public byte randomByte()

Description copied from class: RandomBitsSource

Generate a random byte.

Specified by:

randomByte in class RandomBitsSource

seed

public void seed(byte[] seed)

Description copied from class: RandomBitsSource

Seed the PRNG with the supplied array of bytes.

Specified by:

seed in class RandomBitsSource

seed

public void seed(EntropySource egs)

Description copied from class: RandomBitsSource

Seed the PRNG with a default number of bytes from the supplied entropy source.

Note that entropy source algorithms are frequently time and/or resource-intensive, which may cause significant delay before this method returns.

Specified by:

seed in class RandomBitsSource
