java实现双向RSA + AES加密

本文主要讲解在APP上如何实现双向RSA + AES加密。

先上一张主要流程图：

场景预设：

由于客户端是APP而不是网页，APP在第一次加载的时候会生成一对RSA秘钥对(我们称它为APP公钥私钥，不同APP的秘钥对不一样)，生成以后就写在配置文件里，而且每次都不变，这样可以保证Server公钥和APP公钥不会在网络上明文传输，从而避免了被掉包的可能。服务器也生成一对RSA秘钥对(我们称它为Server公钥私钥)，也是不可修改的。APP端也会事先将服务端的Server公钥写死在配置文件里。主要的交互流程如上图所示。

接下来上代码

package com.zhuyun.encrypt;
 
import java.io.IOException;
 
import javax.crypto.Cipher;
import javax.crypto.KeyGenerator;
import javax.crypto.SecretKey;
import javax.crypto.spec.SecretKeySpec;
 
import sun.misc.BASE64Decoder;
import sun.misc.BASE64Encoder;
 
public class AESUtil {
    //生成AES秘钥，然后Base64编码
    public static String genKeyAES() throws Exception{
        KeyGenerator keyGen = KeyGenerator.getInstance("AES");
        keyGen.init(128);
        SecretKey key = keyGen.generateKey();
        String base64Str = byte2Base64(key.getEncoded());
        return base64Str;
    }
    
    //将Base64编码后的AES秘钥转换成SecretKey对象
    public static SecretKey loadKeyAES(String base64Key) throws Exception{
        byte[] bytes = base642Byte(base64Key);
        SecretKeySpec key = new SecretKeySpec(bytes, "AES");
        return key;
    }
    
    //加密
    public static byte[] encryptAES(byte[] source, SecretKey key) throws Exception{
        Cipher cipher = Cipher.getInstance("AES");
        cipher.init(Cipher.ENCRYPT_MODE, key);
        return cipher.doFinal(source);
    }
    
    //解密
    public static byte[] decryptAES(byte[] source, SecretKey key) throws Exception{
        Cipher cipher = Cipher.getInstance("AES");
        cipher.init(Cipher.DECRYPT_MODE, key);
        return cipher.doFinal(source);
    }
    
    //字节数组转Base64编码
    public static String byte2Base64(byte[] bytes){
        BASE64Encoder encoder = new BASE64Encoder();
        return encoder.encode(bytes);
    }
    
    //Base64编码转字节数组
    public static byte[] base642Byte(String base64Key) throws IOException{
        BASE64Decoder decoder = new BASE64Decoder();
        return decoder.decodeBuffer(base64Key);
    }
}

RSA工具类：RSAUtil

package com.zhuyun.encrypt;
 
import java.io.IOException;
import java.security.KeyFactory;
import java.security.KeyPair;
import java.security.KeyPairGenerator;
import java.security.PrivateKey;
import java.security.PublicKey;

import sun.misc.BASE64Decoder;
import sun.misc.BASE64Encoder;
 
public class RSAUtil {
    //生成秘钥对
    public static KeyPair getKeyPair() throws Exception {
        KeyPairGenerator keyPairGenerator = KeyPairGenerator.getInstance("RSA");
        keyPairGenerator.initialize(2048);
        KeyPair keyPair = keyPairGenerator.generateKeyPair();
        return keyPair;
    }
    
    //获取公钥(Base64编码)
    public static String getPublicKey(KeyPair keyPair){
        PublicKey publicKey = keyPair.getPublic();
        byte[] bytes = publicKey.getEncoded();
        return byte2Base64(bytes);
    }
    
    //获取私钥(Base64编码)
    public static String getPrivateKey(KeyPair keyPair){
        PrivateKey privateKey = keyPair.getPrivate();
        byte[] bytes = privateKey.getEncoded();
        return byte2Base64(bytes);
    }
    
    //将Base64编码后的公钥转换成PublicKey对象
    public static PublicKey string2PublicKey(String pubStr) throws Exception{
        byte[] keyBytes = base642Byte(pubStr);
        X509EncodedKeySpec keySpec = new X509EncodedKeySpec(keyBytes);
        KeyFactory keyFactory = KeyFactory.getInstance("RSA");
        PublicKey publicKey = keyFactory.generatePublic(keySpec);
        return publicKey;
    }
    
    //将Base64编码后的私钥转换成PrivateKey对象
    public static PrivateKey string2PrivateKey(String priStr) throws Exception{
        byte[] keyBytes = base642Byte(priStr);
        PKCS8EncodedKeySpec keySpec = new PKCS8EncodedKeySpec(keyBytes);
        KeyFactory keyFactory = KeyFactory.getInstance("RSA");
        PrivateKey privateKey = keyFactory.generatePrivate(keySpec);
        return privateKey;
    }
    
    //公钥加密
    public static byte[] publicEncrypt(byte[] content, PublicKey publicKey) throws Exception{
        Cipher cipher = Cipher.getInstance("RSA");
        cipher.init(Cipher.ENCRYPT_MODE, publicKey);
        byte[] bytes = cipher.doFinal(content);
        return bytes;
    }
    
    //私钥解密
    public static byte[] privateDecrypt(byte[] content, PrivateKey privateKey) throws Exception{
        Cipher cipher = Cipher.getInstance("RSA");
        cipher.init(Cipher.DECRYPT_MODE, privateKey);
        byte[] bytes = cipher.doFinal(content);
        return bytes;
    }
    
    //字节数组转Base64编码
    public static String byte2Base64(byte[] bytes){
        BASE64Encoder encoder = new BASE64Encoder();
        return encoder.encode(bytes);
    }
    
    //Base64编码转字节数组
    public static byte[] base642Byte(String base64Key) throws IOException{
        BASE64Decoder decoder = new BASE64Decoder();
        return decoder.decodeBuffer(base64Key);
    }
}

接下来是服务端的秘钥对(Server公钥和私钥)，我们选择写死在了代码里：KeyUtil

package com.zhuyun.encrypt;
 
public class KeyUtil {
    //服务端的RSA公钥(Base64编码)
    public final static String SERVER_PUBLIC_KEY = "MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEApkixN3Dc6BLzb/V74VpxRXsSIu9AabGm"

    //服务端的RSA私钥(Base64编码)
    public final static String SERVER_PRIVATE_KEY = "MIIEvAIBADANBgkqhkiG9w0BAQEFAASCBKYwggSiAgEAAoIBAQCmSLE3cNzoEvNv9XvhWnFFexIi"

}

接下来是主要的交互代码了，从流程图可以看出大体分为四个步骤：APP加密，Server解密，Server加密，APP解密。 我们把它封装成了四个方法，对外可直接调用：

HttpEncryptUtil

package com.zhuyun.encrypt;
 
import java.security.PrivateKey;
import java.security.PublicKey;
 
import javax.crypto.SecretKey;
 
import net.sf.json.JSONObject;
 
 
public class HttpEncryptUtil {
 
    //APP加密请求内容
    public static String appEncrypt(String appPublicKeyStr, String content) throws Exception{
        //将Base64编码后的Server公钥转换成PublicKey对象
        PublicKey serverPublicKey = RSAUtil.string2PublicKey(KeyUtil.SERVER_PUBLIC_KEY);
        //每次都随机生成AES秘钥
        String aesKeyStr = AESUtil.genKeyAES();
        SecretKey aesKey = AESUtil.loadKeyAES(aesKeyStr);
        //用Server公钥加密AES秘钥
        byte[] encryptAesKey = RSAUtil.publicEncrypt(aesKeyStr.getBytes(), serverPublicKey);
        //用AES秘钥加密APP公钥
        byte[] encryptAppPublicKey = AESUtil.encryptAES(appPublicKeyStr.getBytes(), aesKey);
        //用AES秘钥加密请求内容
        byte[] encryptRequest = AESUtil.encryptAES(content.getBytes(), aesKey);
        
        JSONObject result = new JSONObject();
        result.put("ak", RSAUtil.byte2Base64(encryptAesKey).replaceAll("\r\n", ""));
        result.put("apk", RSAUtil.byte2Base64(encryptAppPublicKey).replaceAll("\r\n", ""));
        result.put("ct", RSAUtil.byte2Base64(encryptRequest).replaceAll("\r\n", ""));
        return result.toString();
    }
    
    //APP解密服务器的响应内容
    public static String appDecrypt(String appPrivateKeyStr, String content) throws Exception{

        PrivateKey appPrivateKey = RSAUtil.string2PrivateKey(appPrivateKeyStr);
        //用APP私钥解密AES秘钥
        byte[] aesKeyBytes = RSAUtil.privateDecrypt(RSAUtil.base642Byte(encryptAesKeyStr), appPrivateKey);
        //用AES秘钥解密请求内容
        SecretKey aesKey = AESUtil.loadKeyAES(new String(aesKeyBytes));
        byte[] response = AESUtil.decryptAES(RSAUtil.base642Byte(encryptContent), aesKey);
        
        return new String(response);
    }
    
    //服务器加密响应给APP的内容
    public static String serverEncrypt(String appPublicKeyStr, String aesKeyStr, String content) throws Exception{
        //将Base64编码后的APP公钥转换成PublicKey对象
        PublicKey appPublicKey = RSAUtil.string2PublicKey(appPublicKeyStr);
        //将Base64编码后的AES秘钥转换成SecretKey对象
        SecretKey aesKey = AESUtil.loadKeyAES(aesKeyStr);
        //用APP公钥加密AES秘钥
        byte[] encryptAesKey = RSAUtil.publicEncrypt(aesKeyStr.getBytes(), appPublicKey);
        //用AES秘钥加密响应内容
        byte[] encryptContent = AESUtil.encryptAES(content.getBytes(), aesKey);
        
        JSONObject result = new JSONObject();
        result.put("ak", RSAUtil.byte2Base64(encryptAesKey).replaceAll("\r\n", ""));
        result.put("ct", RSAUtil.byte2Base64(encryptContent).replaceAll("\r\n", ""));
        return result.toString();
    }
    
    //服务器解密APP的请求内容
    public static String serverDecrypt(String content) throws Exception{
        JSONObject result = JSONObject.fromObject(content);
        String encryptAesKeyStr = (String) result.get("ak");
        String encryptAppPublicKeyStr = (String) result.get("apk");
        String encryptContent = (String) result.get("ct");
        
        //将Base64编码后的Server私钥转换成PrivateKey对象
        PrivateKey serverPrivateKey = RSAUtil.string2PrivateKey(KeyUtil.SERVER_PRIVATE_KEY);
        //用Server私钥解密AES秘钥
        byte[] aesKeyBytes = RSAUtil.privateDecrypt(RSAUtil.base642Byte(encryptAesKeyStr), serverPrivateKey);
        //用AES秘钥解密APP公钥
        SecretKey aesKey = AESUtil.loadKeyAES(new String(aesKeyBytes));
        byte[] appPublicKeyBytes = AESUtil.decryptAES(RSAUtil.base642Byte(encryptAppPublicKeyStr), aesKey);
        //用AES秘钥解密请求内容
        byte[] request = AESUtil.decryptAES(RSAUtil.base642Byte(encryptContent), aesKey);
        
        JSONObject result2 = new JSONObject();
        result2.put("ak", new String(aesKeyBytes));
        result2.put("apk", new String(appPublicKeyBytes));
        result2.put("ct", new String(request));
        return result2.toString();
    }
}

上面的过程需要APP从客户端的配置文件读取APP公钥和私钥，配置文件内容如下：

最后将它放入了Web项目中，部署在tomcat上面，在相同的环境下大概测试了一下API的吞吐量，如下：

	普通http	https	http加密(本文的方法)
同步	10000 TPS	460 TPS	760 TPS
异步	9000 TPS	760 TPS	1250 TPS

实验表明，在相同环境下它是https方法的吞吐量的1.6倍左右，而且比https更加安全，不过仅限于APP端，在浏览器上不适用。
