MD5 utility

MD5 Utility is a set of tool in Java that calculates and verifies MD5 hashes. You can use MD5 algorithm in any preferred programming language to encrypt and verify the signature while creating a redirection URL.

Sample using Java

copy
package com.alipay.iopentools;
import java.math.BigInteger;
import java.security.MessageDigest;
import java.security.NoSuchAlgorithmException;
/**
 * MD5 encryption/authentication tool class
 */
public class MD5Utils1 {
    /**
     * String encrypted to MD5 without salt
     *
     * @param plainText Pass in the string to be encrypted
     * @return Generate 32-bit (lowercase letters + numbers) string after MD5 encryption
     */
    public static String MD5Lower(String plainText) {
        try {
            MessageDigest md = MessageDigest.getInstance("MD5");
            md.update(plainText.getBytes());
            return new BigInteger(1, md.digest()).toString(16);
        } catch (NoSuchAlgorithmException e) {
            e.printStackTrace();
            return null;
        }
    }
    /**
     * Test
     *
     * @param args
     */
    public static void main(String[] args) {
        String sign_data = "partnerId=*****&extBizPartnerId=*****&redirectUrl=*****&referenceCustomerId=*****&storeUrl=*****&storeName=*****p&currency=USD&requestId=*****&key=*****@***.***";
        String signature = MD5Lower(sign_data);
        System.out.println(signature);
    }
}

Sample using Linux command

copy
echo -n "partnerId=*****&extBizPartnerId=*****&redirectUrl=*****&referenceCustomerId=*****&storeUrl=*****&storeName=*****p&currency=USD&requestId=*****&key=*****@***.***" | md5sum
