Method Detail

withPRF

public FipsKDF.FeedbackModeParametersBuilder withPRF(FipsKDF.PRF prf)

Return a new parameters builder based around the passed in PRF.

Parameters:

prf - the PRF to be used in the final KDF.

Returns:

a new parameters builder.

withR

public FipsKDF.FeedbackModeParametersBuilder withR(int r)

Return a new parameters builder based around the passed in counter size. The counter will be after the iteration data.

Parameters:

r - the length in bits of the counter to be used.

Returns:

a new parameters builder.

withRAndLocation

public FipsKDF.FeedbackModeParametersBuilder withRAndLocation(int r,
                                                              FipsKDF.CounterLocation counterLocation)

Return a new parameters builder based around the passed in counter size and counter position.

Parameters:

r - the length in bits of the counter to be used.

counterLocation - the location of the counter in data passed to the PRF during calculation.

Returns:

a new parameters builder.

using

public FipsKDF.FeedbackModeParameters using(byte[] ki,
                                            byte[] iv,
                                            byte[] fixedInputData)

Return a new parameter set for ki and a prefix.

Parameters:

ki - derivation key for the KDF.

iv - the IV to use at the start of the calculation.

fixedInputData - fixed input data to use in calculation.

Returns:

a FeedbackModeParameters object.

using

public FipsKDF.FeedbackModeParameters using(byte[] ki,
                                            byte[] iv,
                                            byte[] label,
                                            byte[] context,
                                            int L)

Build method for parameters which builds fixed input as outlined in SP 800-108 with the fixed input as a prefix, or suffix, to the counter.

Parameters:

ki - input key.

iv - initialization vector.

label - label - fixed input component.

context - context - fixed input component.

L - number of bits per request for the KDF these parameters will initialise - fixed input component.

Returns:

a FeedbackModeParameters object.
