Method Detail

fromDefaultEntropy

public FipsDRBG.Builder fromDefaultEntropy()

Return a builder using an EntropySourceProvider based on the default SecureRandom with predictionResistant set to false.

Any SecureRandom created from a builder constructed like this will make use of input passed to SecureRandom.setSeed() if the default SecureRandom does for its generateSeed() call.

Returns:

a new Builder instance.

fromEntropySource

public FipsDRBG.Builder fromEntropySource(java.security.SecureRandom entropySource,
                                          boolean predictionResistant)

Construct a builder with an EntropySourceProvider based on the passed in SecureRandom and the passed in value for prediction resistance.

Any SecureRandom created from a builder constructed like this will make use of input passed to SecureRandom.setSeed() if the passed in SecureRandom does for its generateSeed() call.

Parameters:

entropySource - a source of entropy.

predictionResistant - true if this entropySource is prediction resistant, false otherwise.

Returns:

a new Builder instance.

fromEntropySource

public FipsDRBG.Builder fromEntropySource(EntropySourceProvider entropySourceProvider)

Create a builder which makes creates the SecureRandom objects from a specified entropy source provider.

Note: If this method is used any calls to setSeed() in the resulting SecureRandom will be ignored.

Parameters:

entropySourceProvider - a provider of EntropySource objects.

Returns:

a new Builder instance.
