对称加密算法DES实现

什么是对称加密 ？

在对称加密算法中，使用的密钥只有一个，发收信双方都使用这个密钥对数据进行加密和解密，这就要求解密方事先必须知道加密密钥(所以密钥的保密性对通信的安全性至关重要。)

使用场景

在用户登录的时候  需要获取临时登陆凭证token来证明该用户是被信任的， 那怎么获取 临时登录凭证呐？

比较常见的方式是用手机号验证码验证。另一种就是用对称密钥的实现

本案列提供三种实现方式 ：java版，js版，小程序版

java 代码实现

import org.apache.commons.codec.binary.Hex;

import javax.crypto.Cipher;
import javax.crypto.spec.SecretKeySpec;

/**
 * 采用3DES加密，单des密钥是8字节，三重des密钥就是3*8=24字节,更加安全
 * 即密钥必须是24位
 */
public class TripleDes {

    private TripleDes(){}

    private static  Cipher DES_CIPHER;
    static {
        try {
            DES_CIPHER = Cipher.getInstance("DESede/ECB/PKCS5Padding");
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    /**
     * 加密
     * @param str 明文字符串
     * @param key 密钥（必须24位）
     * @return
     */
    public static String encrypt3DES(String str, String key) {
        try {
            DES_CIPHER.init(Cipher.ENCRYPT_MODE, new SecretKeySpec(key.getBytes("utf-8"), "DESede"));
            byte[] encryptedData = DES_CIPHER.doFinal(str.getBytes("utf-8"));
            //转化为字符串
            return Hex.encodeHexString(encryptedData).toUpperCase();
        } catch (Exception e) {
            e.printStackTrace();
        }
        return null;
    }

    /**
     * 解密
     * @param str 密码后的密文
     * @param key 密钥（必须24位）
     * @return
     */
    public static String decrypt3DES(String str, String key) {
        try {
            DES_CIPHER.init(Cipher.DECRYPT_MODE, new SecretKeySpec(key.getBytes("utf-8"), "DESede"));
            byte[] decryptedData = DES_CIPHER.doFinal(Hex.decodeHex(str.toCharArray()));
            return new String(decryptedData, "utf-8");
        } catch (Exception e) {
            e.printStackTrace();
        }
        return null;
    }


    public static void main(String[] args) {
        String str = "helloWorld1523";
        String key = "555555555555555555555555";// 24位密钥
        String s = encrypt3DES(str, key);
        System.out.println("密文："+s);
        String s1 = decrypt3DES(s, key);
        System.out.println("明文："+s1);
    }

}

 注：本次为了演示方便密钥写了24个5

运行结果

密文：86BF8FB9B63E3D7892DE68238196B1CB
明文：helloWorld1523

 js 代码实现

首先需要引入两个js分别是tripledes.js,mode-ecb.js 后续有这两个文件复制出来即可

加密方法

/**
 * 加密
 * @param {String} str 需要加密的字符串
 * @param {String} key 密钥（24位）
 */
function encryptByDES(str, key) {
    var keyHex = CryptoJS.enc.Utf8.parse(key);
    var encrypted = CryptoJS.TripleDES.encrypt(str, keyHex, {
        mode: CryptoJS.mode.ECB,
        padding: CryptoJS.pad.Pkcs7  //后端pkcs5填充，前端对应pkcs7
    });
    return encrypted.toString()
}


/**
 * 
 * @param {String} str 需要解密的字符串
 * @param {String} key 密钥（24位）
 */
function decryptByDES(str, key) {
    var keyHex = CryptoJS.enc.Utf8.parse(key);
    var decrypted = CryptoJS.TripleDES.decrypt(str, keyHex, {
        mode:CryptoJS.mode.ECB,
        padding: CryptoJS.pad.Pkcs7 //后端pkcs5填充，前端对应pkcs7
    });
    return decrypted.toString(CryptoJS.enc.Utf8)
}

前端运行 并打印结果

 

 将客户端生成的密钥粘贴到后台进行解密看

 密文解密成功

 

小程序客户端实现

方式与以上js方式几乎一样，唯一不同的是引入方式不同可自行调整 ，需要用到 tripledes.js,mode-ecb.js,desUtil.js
