Constructor Detail

TestRandomEntropySourceProvider

public TestRandomEntropySourceProvider(boolean isPredictionResistant)

Create a test entropy source provider.

Parameters:

isPredictionResistant - boolean indicating if the SecureRandom is based on prediction resistant entropy or not (true if it is).

Method Detail

get

public EntropySource get(int bitsRequired)

Return an entropy source that will create bitsRequired bits of entropy on each invocation of getEntropy().

Specified by:

get in interface EntropySourceProvider

Parameters:

bitsRequired - size (in bits) of entropy to be created by the provided source.

Returns:

an EntropySource that generates bitsRequired bits of entropy on each call to its getEntropy() method.
