Interface parameter signature process

content

Parameter Name	Required	Type	Length Limit	Example	Description
appId	Yes	string	-	45eebd745dcf0b5f6d6f9fcde28cd9fe8116a892	app id (provided by SwiMove)
storeKey	Yes	string	100	CVIEIYUNHTS0	store key (provided by SwiMove)
param	Yes	string	-	-	request param content string
sign	Yes	string	-		RSA sign of param

give typical examples

{
   "appId": "45eebd745dcf0b5f6d6f9fcde28cd9fe8116a892",
   "storeKey": "CVIEIYUNHTS0",
   "sign": "abcdef",
   "param": "{}"
}

explanation

1. appId is a fixed value provided by SwiMove
2. According to the specific interface document, construct the request parameter, format the request parameter into JSON format, and use it as the value of param;
3. Use the RSA private key to sign param, and the resulting value is used as the value of sign.

appendix rsa usage example java language

Generate an RSA key pair:

import java.security.*;
import java.util.Base64;

public class RsaGenerateKeyPair {
    public static void main(String[] args) throws NoSuchAlgorithmException {
        KeyPairGenerator keyPairGenerator = KeyPairGenerator.getInstance("RSA");
        keyPairGenerator.initialize(2048);
        KeyPair keyPair = keyPairGenerator.genKeyPair();

        PublicKey publicKey = keyPair.getPublic();
        byte[] publicKeyBytes = publicKey.getEncoded();
        String publicKeyBase64 = Base64.getEncoder().encodeToString(publicKeyBytes);
        System.out.println(publicKeyBase64);

        PrivateKey privateKey = keyPair.getPrivate();
        byte[] privateKeyBytes = privateKey.getEncoded();
        String privateKeyBase64 = Base64.getEncoder().encodeToString(privateKeyBytes);
        System.out.println(privateKeyBase64);
    }
}

Please submit the RSA public key to SwiMove, please do not disclose it to any third party.

The RSA private key is kept by the merchant, please do not disclose it to anyone.

When a merchant requests SwiMove Open API, the merchant uses the RSA private key to sign the request parameters, and PayCools will use the RSA public key provided by the merchant to verify the signature in the request. If authentication fails, the PayCools server refuses to process the request.
