### Usage

#### I- Add dependencies to ```pom.xml``` file

```xml

 

    com.tryspare

    java.sdk

    1.1.0

 

``` 

#### II- To Generate ECC key pair

```java

import com.spare.sdk.security.crypto.SpCrypto;

public class MyClass {

    SpEcKeyPair eccKeyPair = SpCrypto.generateKeyPair();

    

    System.out.println("Private key \n", eccKeyPair.getPrivateKey());

    System.out.println("\n\n");

    System.out.println("Private key \n", eccKeyPair.getPublicKey());

}

```

#### III- To create your first payment request

```java

import com.spare.sdk.payment.models.builder.SpDomesticPaymentRequestBuilder;

import com.spare.sdk.payment.models.payment.domestic.SpDomesticPaymentRequest;

public class MyClass {

    // Business ECC private key

    public static String privateKey = """""";

    // Spare ECC public key

    public static String serverPublicKey = """""";

    public static void main(String[] args) {

        // Configure client

        SpPaymentClientOptions clientOptions = new SpPaymentClientOptions();

        clientOptions.setBaseUrl(URI.create("https://payment.tryspare.com"));

        clientOptions.setApiKey("Your API key");

        clientOptions.setAppId("Your app id");

        SpPaymentClient client = new SpPaymentClient(clientOptions);

        // Initialize payment

        SpDomesticPaymentRequestBuilder paymentRequestBuilder = new SpDomesticPaymentRequestBuilder();

        SpDomesticPaymentRequest paymentRequest = paymentRequestBuilder.setAmount(10.0)

                .setDescription("Shopping")

                .setOrderId("12345")

                .build();

        // Sign the payment 

        String signature = SpEccSignatureManager.Sign(privateKey, paymentRequest.toJsonString());

        // Create payment

        SpCreateDomesticPaymentResponse paymentResponse = client.CreateDomesticPayment(paymentRequest, signature);

        // To verify signature of the created payment 

        if (SpEccSignatureManager.Verify(serverPublicKey, paymentResponse.getPayment().toJsonString(), createPayment.getSignature())) {

            // signature verified

        }

    }

}
