      public MQVParameterSpec(PublicKey ephemeralPublicKey, PrivateKey ephemeralPrivateKey, PublicKey otherPartyEphemeralKey, AlgorithmParameterSpec kdfParameterSpec)
      Base constructor.
      Parameters:
      ephemeralPublicKey - our ephemeral public key.
      ephemeralPrivateKey - our ephemeral private key.
      otherPartyEphemeralKey - the ephemeral public key sent by the other party.
      kdfParameterSpec - parameter spec for key generator to mix with the calculated secret.

    • MQVParameterSpec

      public MQVParameterSpec(PublicKey ephemeralPublicKey, PrivateKey ephemeralPrivateKey, PublicKey otherPartyEphemeralKey, byte[] userKeyingMaterial)
      Base constructor.
      Parameters:
      ephemeralPublicKey - our ephemeral public key.
      ephemeralPrivateKey - our ephemeral private key.
      otherPartyEphemeralKey - the other party's ephemeral public key.
      userKeyingMaterial - the user keying material for the key derivation function.

    • MQVParameterSpec

      public MQVParameterSpec(PublicKey ephemeralPublicKey, PrivateKey ephemeralPrivateKey, PublicKey otherPartyEphemeralKey)
      Constructor without user keying material.
      Parameters:
      ephemeralPublicKey - our ephemeral public key.
      ephemeralPrivateKey - our ephemeral private key.
      otherPartyEphemeralKey - the other party's ephemeral public key.

    • MQVParameterSpec

      public MQVParameterSpec(KeyPair ephemeralKeyPair, PublicKey otherPartyEphemeralKey, byte[] userKeyingMaterial)
      Constructor taking an ephemeral key pair.
      Parameters:
      ephemeralKeyPair - keypair holding our ephemeral public and private keys.
      otherPartyEphemeralKey - the other party's ephemeral public key.
      userKeyingMaterial - the user keying material for the key derivation function.

    • MQVParameterSpec

      public MQVParameterSpec(KeyPair ephemeralKeyPair, PublicKey otherPartyEphemeralKey, AlgorithmParameterSpec kdfParameterSpec)
      Constructor taking an ephemeral key pair and an algorithm spec.
      Parameters:
      ephemeralKeyPair - keypair holding our ephemeral public and private keys.
      otherPartyEphemeralKey - the other party's ephemeral public key.
      kdfParameterSpec - parameter spec for key generator to mix with the calculated secret.

    • MQVParameterSpec

      public MQVParameterSpec(PrivateKey ephemeralPrivateKey, PublicKey otherPartyEphemeralKey, byte[] userKeyingMaterial)
      Constructor without our ephemeral public key - in this case it is assumed the ephemeral public key can be calculated later.
      Parameters:
      ephemeralPrivateKey - our ephemeral private key.
      otherPartyEphemeralKey - the other party's ephemeral public key.
      userKeyingMaterial - the user keying material for the key derivation function.

    • MQVParameterSpec

      Parameters:
      ephemeralPrivateKey - our ephemeral private key.
      otherPartyEphemeralKey - the other party's ephemeral public key.
      kdfParameterSpec - parameter spec for key generator to mix with the calculated secret.

    • MQVParameterSpec

      public MQVParameterSpec(KeyPair ephemeralKeyPair, PublicKey otherPartyEphemeralKey)
      Constructor taking an ephemeral key pair without user keying material.
      Parameters:
      ephemeralKeyPair - keypair holding our ephemeral public and private keys.
