Method Details

getFunctionOutput

public byte[] getFunctionOutput(int outLen)

Description copied from interface: OutputXOFCalculator

Return the outLen bytes of function output for what has been written to the calculator's output stream.

Specified by:

getFunctionOutput in interface OutputXOFCalculator<T extends FipsParameters>

Parameters:

outLen - the number of output bytes requested.

Returns:

a byte array containing outLen bytes of output.

getParameters

public abstract T getParameters()

Description copied from interface: OutputXOFCalculator

Return the parameters for this XOF calculator.

Specified by:

getParameters in interface OutputXOFCalculator<T extends FipsParameters>

Returns:

the XOF calculator's parameters.

getFunctionStream

public abstract UpdateOutputStream getFunctionStream()

Description copied from interface: OutputXOFCalculator

Returns a stream that will accept data for the purpose of calculating a MAC. Use org.bouncycastle.util.io.TeeOutputStream if you want to accumulate the data on the fly as well.

Specified by:

getFunctionStream in interface OutputXOFCalculator<T extends FipsParameters>

Returns:

an UpdateOutputStream

getFunctionOutput

public abstract int getFunctionOutput(byte[] output,
 int off,
 int outLen)

Description copied from interface: OutputXOFCalculator

Output the function output for what has been written to the calculator's output stream.

Specified by:

getFunctionOutput in interface OutputXOFCalculator<T extends FipsParameters>

Parameters:

output - output array to write the output bytes to.

off - offset to start writing the bytes at.

outLen - the number of output bytes requested.

Returns:

the number of bytes written

reset

public abstract void reset()

Description copied from interface: OutputXOFCalculator

Reset the calculator back to its initial state.

Specified by:

reset in interface OutputXOFCalculator<T extends FipsParameters>
