  • Method Details

    • getEphemeralPublicKey

      public AsymmetricECPublicKey getEphemeralPublicKey()
      Return our ephemeral public key, if present.
      Returns:
      our ephemeral public key, or null.

    • getEphemeralPrivateKey

      public AsymmetricECPrivateKey getEphemeralPrivateKey()
      Return our ephemeral private key.
      Returns:
      our ephemeral private key.

    • getOtherPartyEphemeralKey

      public AsymmetricECPublicKey getOtherPartyEphemeralKey()
      Return the other party's ephemeral public key.
      Returns:
      the other party's ephemeral public key.

    • withDigest

      public FipsEC.MQVAgreementParameters 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 FipsEC.MQVAgreementParameters 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 FipsEC.MQVAgreementParameters 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 builder 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.
