  • Method Details

    • 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.
