Android Https双向认证 + GRPC

keywords:android https 双向认证android GRPC https 双向认证

ManagedChannel channel = OkHttpChannelBuilder.forAddress("xxx",yyy)
                        .overrideAuthority("zzz")
                        .sslSocketFactory(sslFactory)
                        .build();

1、千万不要像官网案例那样设置setPlaintext(true)，这个是设置明文，我们用的是密文

2、xxx是服务器的ip，yyy是端口号，zzz是domain（这些参数服务端都会提供给你）

特别注意这个overrideAuthority一定要调用，覆盖hostname来匹配服务器的证书

3、sslSocketFactory这个方法就是设置密钥的方法。一般服务端会提供个.pem的密钥文件，放在raw中。我们把这个密钥设置到OkHttpChannelBuilder中即可以访问服务器了，关于sslSocketFactory 网上可以搜索到很多有关的内容。

cert files gen:

# Generates client.crt which is the clientCertChainFile for the client (need for mutual TLS only)
openssl x509 -passin pass:1111 -req -days 365 -in client.csr -CA ca.crt -CAkey ca.key -set_serial 01 -out client.crt
echo Remove passphrase from client key:
openssl rsa -passin pass:1111 -in client.key -out client.key
echo Converting the private keys to X.509:
# Generates client.pem which is the clientPrivateKeyFile for the Client (needed for mutual TLS only)
openssl pkcs8 -topk8 -nocrypt -in client.key -out client.pem
# Generates server.pem which is the privateKeyFile for the Server
openssl pkcs8 -topk8 -nocrypt -in server.key -out server.pem

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：

OkHttpClient okHttpClient = new OkHttpClient.Builder()
    .sslSocketFactory(SSLHelper.getSSLCertifcation(context))//为OkHttp对象设置SocketFactory用于双向认证
    .hostnameVerifier(new UnSafeHostnameVerifier())
    .build();
Retrofit retrofit = new Retrofit.Builder()
    .baseUrl("https://10.2.8.56:8443")
    .addConverterFactory(GsonConverterFactory.create())//添加 json 转换器
    .addCallAdapterFactory(RxJavaCallAdapterFactory.create())//添加 RxJava 适配器
    .client(okHttpClient)//添加OkHttp代理对象
    .build();
