Method Details

getStrength

public int getStrength()

Returns the security strength requested in bits.

Returns:: the strength requested, or -1 if the effective strength should be used.

getPredictionResistance

public boolean getPredictionResistance()

Returns whether prediction resistance is requested.

Returns:: whether prediction resistance is requested

getAdditionalInput

public byte[] getAdditionalInput()

Returns the requested additional input.

Returns:: the requested additional input, null if not requested. A new byte array is returned each time this method is called.
