Method Detail

acceptEntropy

public int acceptEntropy(EntropySource source,
                         long data,
                         int entropyGuess)

Description copied from class: RandomSource

Accepts entropy data from a source

Specified by:

acceptEntropy in class RandomSource

acceptTimerEntropy

public int acceptTimerEntropy(EntropySource timer)

Description copied from class: RandomSource

Accepts entropy in the form of timing data from a source

Specified by:

acceptTimerEntropy in class RandomSource

acceptTimerEntropy

public int acceptTimerEntropy(EntropySource fnpTimingSource,
                              double bias)

Description copied from class: RandomSource

Accept entropy from a source with a bias

Specified by:

acceptTimerEntropy in class RandomSource

bias - Value by which we multiply the entropy before counting it. Must be <= 1.0.

acceptEntropyBytes

public int acceptEntropyBytes(EntropySource myPacketDataSource,
                              byte[] buf,
                              int offset,
                              int length,
                              double bias)

Description copied from class: RandomSource

Accepts larger amounts of entropy data from a source, with a bias

Specified by:

acceptEntropyBytes in class RandomSource

Parameters:

myPacketDataSource - The source from which the data has come.

buf - The buffer to read bytes from.

offset - The offset to start reading from.

length - The number of bytes to read.

bias - The bias. Value by which we multiply the entropy before counting it. Must be <= 1.0.

close

public void close()

Description copied from class: RandomSource

If the RandomSource has any resources it wants to close, it can do so when this method is called

Specified by:

close in class RandomSource
