ECDHChaveiros Raw

// Instantiate material providers
var materialProviders = new MaterialProviders(new MaterialProvidersConfig());
	    var BobPrivateKey = new MemoryStream(new byte[] { });
	    var AlicePublicKey = new MemoryStream(new byte[] { });

	    // Create the Raw ECDH static keyring
	    var staticConfiguration = new RawEcdhStaticConfigurations()
	    {
		    RawPrivateKeyToStaticPublicKey = new RawPrivateKeyToStaticPublicKeyInput
		    {
			    SenderStaticPrivateKey = BobPrivateKey,
			    RecipientPublicKey = AlicePublicKey
		    }
	    };
	    
	    var createKeyringInput = new CreateRawEcdhKeyringInput() 
	    {
		    CurveSpec = ECDHCurveSpec.ECC_NIST_P256,
		    KeyAgreementScheme = staticConfiguration 
	    };

	    var keyring = materialProviders.CreateRawEcdhKeyring(createKeyringInput);

O exemplo Java a seguir usa o esquema de contrato de RawPrivateKeyToStaticPublicKey chave para configurar estaticamente a chave privada do remetente e a chave pública do destinatário. Ambos os pares de chaves estão na ECC_NIST_P256 curva.

private static void StaticRawKeyring() {
    // Instantiate material providers
    final MaterialProviders materialProviders =
      MaterialProviders.builder()
        .MaterialProvidersConfig(MaterialProvidersConfig.builder().build())
        .build();

    KeyPair senderKeys = GetRawEccKey();
    KeyPair recipient = GetRawEccKey();

    // Create the Raw ECDH static keyring
    final CreateRawEcdhKeyringInput rawKeyringInput =
      CreateRawEcdhKeyringInput.builder()
        .curveSpec(ECDHCurveSpec.ECC_NIST_P256)
        .KeyAgreementScheme(
          RawEcdhStaticConfigurations.builder()
            .RawPrivateKeyToStaticPublicKey(
                RawPrivateKeyToStaticPublicKeyInput.builder()
                  // Must be a PEM-encoded private key
                  .senderStaticPrivateKey(ByteBuffer.wrap(senderKeys.getPrivate().getEncoded()))
                  // Must be a DER-encoded X.509 public key
                  .recipientPublicKey(ByteBuffer.wrap(recipient.getPublic().getEncoded()))
                  .build()
            )
            .build()
        ).build();

    final IKeyring staticKeyring = materialProviders.CreateRawEcdhKeyring(rawKeyringInput);
}

O exemplo a seguir cria um ECDH chaveiro Raw com o esquema de contrato de EphemeralPrivateKeyToStaticPublicKey chave. Ao criptografar, o chaveiro criará um novo par de chaves localmente na curva especificadaECC_NIST_P256.

// Instantiate material providers
var materialProviders = new MaterialProviders(new MaterialProvidersConfig());
	    var AlicePublicKey = new MemoryStream(new byte[] { });

	    // Create the Raw ECDH ephemeral keyring
	    var ephemeralConfiguration = new RawEcdhStaticConfigurations()
	    {
		    EphemeralPrivateKeyToStaticPublicKey = new EphemeralPrivateKeyToStaticPublicKeyInput
		    {
			    RecipientPublicKey = AlicePublicKey
		    }
	    };
	    
	    var createKeyringInput = new CreateRawEcdhKeyringInput() 
	    {
		    CurveSpec = ECDHCurveSpec.ECC_NIST_P256,
		    KeyAgreementScheme = ephemeralConfiguration
	    };

	    var keyring = materialProviders.CreateRawEcdhKeyring(createKeyringInput);

}

O exemplo a seguir cria um ECDH chaveiro Raw com o esquema de contrato de PublicKeyDiscovery chave. Esse chaveiro pode descriptografar qualquer registro em que a chave pública da chave privada especificada corresponda à chave pública do destinatário armazenada no campo de descrição do material do registro criptografado.

// Instantiate material providers
var materialProviders = new MaterialProviders(new MaterialProvidersConfig());
	    var AlicePrivateKey = new MemoryStream(new byte[] { });

	    // Create the Raw ECDH discovery keyring
	    var discoveryConfiguration = new RawEcdhStaticConfigurations()
	    {
		    PublicKeyDiscovery = new PublicKeyDiscoveryInput
		    {
			    RecipientStaticPrivateKey = AlicePrivateKey
