基于Retrofit实现HTTPS思路

由于最近要做一个安全性比较高的项目，因此需要用到HTTPS进行双向认证。客户端基于Retrofit + Rxjava+EventBus来实现

基于Retrofit实现HTTPS思路

由于Retrofit是基于OkHttp实现的，因此想通过Retrofit实现HTTPS需要给Retrofit设置一个OkHttp代理对象用于处理HTTPS的握手过程。代理代码如下：

[java] view plain copy

print ?

mOkHttpClient = new OkHttpClient.Builder()
.hostnameVerifier(new UnSafeHostnameVerifier())//添加hostName验证器
.sslSocketFactory(sslSocketFactory)
.build();
Retrofit retrofit = new Retrofit.Builder()
.addConverterFactory(ScalarsConverterFactory.create())//增加返回值为字符串的支持
.baseUrl(BASE_URL)//主机地址
.client(mOkHttpClient)//注意这里要给retrofit 设置okhttpclient
.build();
private class UnSafeHostnameVerifier implements HostnameVerifier {
@Override
public boolean verify(String hostname, SSLSession session) {
return true;//自行添加判断逻辑，true->Safe，false->unsafe
}
}

mOkHttpClient = new OkHttpClient.Builder()
        .hostnameVerifier(new UnSafeHostnameVerifier())//添加hostName验证器
        .sslSocketFactory(sslSocketFactory)
        .build();

Retrofit retrofit = new Retrofit.Builder()
        .addConverterFactory(ScalarsConverterFactory.create())//增加返回值为字符串的支持
        .baseUrl(BASE_URL)//主机地址
        .client(mOkHttpClient)//注意这里要给retrofit 设置okhttpclient
        .build();

private class UnSafeHostnameVerifier implements HostnameVerifier {
    @Override
    public boolean verify(String hostname, SSLSession session) {
        return true;//自行添加判断逻辑，true->Safe，false->unsafe
    }
}

上面代码可以看到使用Retrofit请求HTTPS主要使用SSLSocketFactory，所以我们只需构建sslSocketFactory。
在我的例子中，我有一个pem文件，它包含一个证书和一个加密的私钥，用于相互SSL身份验证。 因此我的pem文件如下所示：
-----BEGIN RSA PRIVATE KEY-----
......
-----END RSA PRIVATE KEY-----
-----BEGIN CERTIFICATE-----
......
-----END CERTIFICATE-----

如果你得到的私钥如上所示，那你还需要使用openssl执行PKCS8编码:
openssl pkcs8 -topk8 -in rsa_private_key.pem -out pkcs8_rsa_private_key.pem -nocrypt
得到如下私钥
-----BEGIN PRIVATE KEY-----
......
-----END PRIVATE KEY-----
进入代码正文
     
     
      
      创建一个新的java密钥存储并导入私钥和证书：

      
      
       
       
        
        
         
         [java] 
         
         view plain
         
          copy
         
         
         
          print
         
         ?
        
        
       
       
       
       
        
        KeyStore ks = KeyStore.getInstance(KeyStore.getDefaultType());  
        
        ks.load(null, keypass.toCharArray());  
        
        ks.store(new FileOutputStream(getExternalFilesDir(null) + “/xxx.keystore”), keypass.toCharArray());  
        
        ks.load(new FileInputStream(getExternalFilesDir(null) + “/xxx.keystore”), keypass.toCharArray());  
        
          
        
        //读取证书文件  
        
        FileInputStream fileInputStream = new FileInputStream(file);  
        
        byte[] bytes = new byte[fileInputStream.available()];  
        
        fileInputStream.read(bytes);  
        
        //转化为字符串  
        
        String str = new String(bytes);  
        
        //提取出私钥和证书  
        
        String[] s = str.replace(”—–BEGIN PRIVATE KEY—–\n”, “”).split(“\n—–END PRIVATE KEY—–\n”);  
        
          
        
        //  获取指定目录下的证书  
        
        Certificate crt1 = CertificateFactory.getInstance(”X509”).generateCertificate(new FileInputStream(file));  
        
        fileInputStream.close();  
        
          
        
        byte[] bytes1 = Base64.decode(s[0], Base64.DEFAULT);  
        
        //主要代码  
        
        KeyFactory kf = KeyFactory.getInstance(”RSA”);  
        
        PKCS8EncodedKeySpec keysp = new PKCS8EncodedKeySpec(bytes1);  
        
        PrivateKey ff = kf.generatePrivate(keysp);  
        
        //证书链  
        
        Certificate[] chain = new Certificate[]{crt1};  
        
        String mainInformation = ((X509Certificate) crt1).getSubjectX500Principal().getName();  
        
        //获取别名  
        
        String alias = mainInformation.substring((mainInformation.indexOf(”=”) + 1), mainInformation.indexOf(“,”));  
        
        //组合,并添加证书到KeyStore  
        
        ks.setKeyEntry(alias , ff, keypass.toCharArray(), chain);  
       
       
       
       
        
        
       
       
      
      
      
      KeyStore ks = KeyStore.getInstance(KeyStore.getDefaultType());
ks.load(null, keypass.toCharArray());
ks.store(new FileOutputStream(getExternalFilesDir(null) + "/xxx.keystore"), keypass.toCharArray());
ks.load(new FileInputStream(getExternalFilesDir(null) + "/xxx.keystore"), keypass.toCharArray());

//读取证书文件
FileInputStream fileInputStream = new FileInputStream(file);
byte[] bytes = new byte[fileInputStream.available()];
fileInputStream.read(bytes);
//转化为字符串
String str = new String(bytes);
//提取出私钥和证书
String[] s = str.replace("-----BEGIN PRIVATE KEY-----\n", "").split("\n-----END PRIVATE KEY-----\n");

//  获取指定目录下的证书
Certificate crt1 = CertificateFactory.getInstance("X509").generateCertificate(new FileInputStream(file));
fileInputStream.close();

byte[] bytes1 = Base64.decode(s[0], Base64.DEFAULT);
//主要代码
KeyFactory kf = KeyFactory.getInstance("RSA");
PKCS8EncodedKeySpec keysp = new PKCS8EncodedKeySpec(bytes1);
PrivateKey ff = kf.generatePrivate(keysp);
//证书链
Certificate[] chain = new Certificate[]{crt1};
String mainInformation = ((X509Certificate) crt1).getSubjectX500Principal().getName();
//获取别名
String alias = mainInformation.substring((mainInformation.indexOf("=") + 1), mainInformation.indexOf(","));
//组合,并添加证书到KeyStore
ks.setKeyEntry(alias , ff, keypass.toCharArray(), chain);

[java] view plain copy

print ?

//秘钥管理器
KeyManagerFactory kmf = KeyManagerFactory.getInstance(”X509”);
kmf.init(ks, keypass.toCharArray());
KeyManager[] keyManagers = kmf.getKeyManagers();
SSLContext sslContext = SSLContext.getInstance(”TLS”);
sslContext.init(keyManagers, null, null);
SSLSocketFactory sslSocketFactory = sslContext.getSocketFactory();

            //秘钥管理器
            KeyManagerFactory kmf = KeyManagerFactory.getInstance("X509");
            kmf.init(ks, keypass.toCharArray());
            KeyManager[] keyManagers = kmf.getKeyManagers();

            SSLContext sslContext = SSLContext.getInstance("TLS");
            sslContext.init(keyManagers, null, null);

            SSLSocketFactory sslSocketFactory = sslContext.getSocketFactory();

由于我公司服务器证书是ca认证的所以不需要验证 TrustManagerFactory

如果使用的是p12格式证书则只能把证书当作文件的形式读取:

[java] view plain copy

print ?

try {
//创建KeyStore
KeyStore keyStore = KeyStore.getInstance(”PKCS12”);
keyStore .load(getResources().openRawResource(R.raw.certificate_with_key_6), ”U3T2C24RW8”.toCharArray());
//秘钥管理器
KeyManagerFactory kmf = KeyManagerFactory.getInstance(”X509”);
kmf.init(ks, keypass.toCharArray());
KeyManager[] keyManagers = kmf.getKeyManagers();
SSLContext sslContext = SSLContext.getInstance(”TLS”);
sslContext.init(keyManagers, null, null);
SSLSocketFactory sslSocketFactory = sslContext.getSocketFactory();
} catch (Exception e) {
e.printStackTrace();
Log.e(”MainActivity”, “——-错误111——” + e.toString());
}

        try {
            //创建KeyStore

KeyStore keyStore = KeyStore.getInstance("PKCS12");


keyStore .load(getResources().openRawResource(R.raw.certificate_with_key_6), "U3T2C24RW8".toCharArray());

           //秘钥管理器
            KeyManagerFactory kmf = KeyManagerFactory.getInstance("X509");
            kmf.init(ks, keypass.toCharArray());
            KeyManager[] keyManagers = kmf.getKeyManagers();

            SSLContext sslContext = SSLContext.getInstance("TLS");
            sslContext.init(keyManagers, null, null);

            SSLSocketFactory sslSocketFactory = sslContext.getSocketFactory();


        } catch (Exception e) {
            e.printStackTrace();
            Log.e("MainActivity", "-------错误111------" + e.toString());
        }

到此基本代码已完结,欢迎提出意见:
