    • Method Detail

      • withDigest

        public FipsDH.AgreementParameters withDigest​(FipsAlgorithm digestAlgorithm)
        Add a digest algorithm to process the Z value with.
        Parameters:
        digestAlgorithm - digest algorithm to use.
        Returns:
        a new parameter set, including the digest algorithm
      • withPRF

        public FipsDH.AgreementParameters withPRF​(FipsKDF.PRF prfAlgorithm,
                                                  byte[] salt)
        Add a PRF algorithm and salt to process the Z value with (as in SP 800-56C)
        Parameters:
        prfAlgorithm - PRF represent the MAC/HMAC algorithm to use.
        salt - the salt to use to initialise the PRF
        Returns:
        a new parameter set, including the digest algorithm
      • withKDF

        public FipsDH.AgreementParameters withKDF​(FipsKDF.AgreementKDFParametersBuilder kdfType,
                                                  byte[] iv,
                                                  int outputSize)
        Add a KDF to process the Z value with. The outputSize parameter determines how many bytes will be generated.
        Parameters:
        kdfType - KDF algorithm type to use for parameter creation.
        iv - the iv parameter for KDF initialization.
        outputSize - the size of the output to be generated from the KDF.
        Returns:
        a new parameter set, the KDF definition.
