MD5 encryption verification

1. Import dependence

<!--         Join in MD5 Dependencies required for encryption -->

        <dependency>
            <groupId>org.apache.commons</groupId>
            <artifactId>commons-lang3</artifactId>
        </dependency>

        <dependency>
            <groupId>commons-codec</groupId>
            <artifactId>commons-codec</artifactId>
        </dependency>

2. Create a tool class

String KEY_MD5=“easy0afshjd5fshkja48aodkjdf8sfsd”;

package tian.project.easy_to_stop.utils;

import org.apache.commons.codec.digest.DigestUtils;
import tian.project.easy_to_stop.constant.Constant;

/** * MD5 encryption algorithm  */
public class MD5Utils {
    

    /** * MD5 Method  * @param text  Plaintext  * @return  Ciphertext  * @throws Exception */
    public static String md5(String text){
    
        // The encrypted string 
        String encode= DigestUtils.md5Hex(text);
        return encode;
    }

    /** * MD5 Method  * @param text  Plaintext  * @param key  salt  * @return  Ciphertext  * @throws Exception */
    public static String md5(String text, String key){
    
        // The encrypted string 
        String encode= DigestUtils.md5Hex(text + key);
        return encode;
    }

    /** * MD5 Verification method  * @param text  Plaintext  * @param key  secret key  * @param md5  Ciphertext  * @return true/false * @throws Exception */
    public static boolean verify(String text, String key, String md5) throws Exception {
    
        // Verify against the incoming key 
        String md5Text = md5(text, key);
        return md5Text.equalsIgnoreCase(md5);
    }


    public static void main(String[] args) {
    
        // Generate 
        try {
    
            String var = md5("123456", Constant.KEY_MD5);
            System.out.println(var);
            boolean verify=verify("123456",Constant.KEY_MD5,"6eede222b0855e578b2c3813d2836f2d");
            System.out.println(verify);
        } catch (Exception e) {
    
            e.printStackTrace();
        }
    }
}
