Method Summary

Modifier and Type	Method and Description
FipsKDF.CounterModeParameters	using(byte[] ki, boolean isPrefix, 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.
FipsKDF.CounterModeParameters	using(byte[] ki, byte[] fixedInputPrefix) Return a new parameter set for ki and a prefix.
FipsKDF.CounterModeParameters	using(byte[] ki, byte[] fixedInputPrefix, byte[] fixedInputSuffix) Return a new parameter set for ki and the prefix/suffix data.
FipsKDF.CounterModeParametersBuilder	withPRFAndR(FipsKDF.PRF prf, int r) Return a new parameters builder based around the passed in PRF and counter size.

Method Detail

withPRFAndR

public FipsKDF.CounterModeParametersBuilder withPRFAndR(FipsKDF.PRF prf,
                                                        int r)

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

Parameters:

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

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

Returns:

a new parameters builder.

using

public FipsKDF.CounterModeParameters using(byte[] ki,
                                           byte[] fixedInputPrefix)

Return a new parameter set for ki and a prefix.

Parameters:

ki - derivation key for the KDF.

fixedInputPrefix - prefix data to come before the counter during calculation.

Returns:

a CounterModeParameters object.

using

public FipsKDF.CounterModeParameters using(byte[] ki,
                                           byte[] fixedInputPrefix,
                                           byte[] fixedInputSuffix)

Return a new parameter set for ki and the prefix/suffix data.

Parameters:

ki - derivation key for the KDF.

fixedInputPrefix - prefix data to come before the counter during calculation.

fixedInputSuffix - suffix data to come after the counter during calculation.

Returns:

a CounterModeParameters object.

using

public FipsKDF.CounterModeParameters using(byte[] ki,
                                           boolean isPrefix,
                                           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.

isPrefix - is the fixed input a prefix or a suffix.

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 CounterModeParameters object.
