https证书生成、服务器配置、Android端配置
单项认证--服务器配置
生成服务器证书
命令：C:\Users\bwkt>keytool -genkey -alias server -keyalg RSA -keystore server.jks -validity 3650
-genkey：在用户主目录中创建一个默认文件".keystore"
-alias：别名，独一无二，通常不区分大小写
-keyalg： 指定密钥的算法 (如 RSA DSA（如果不指定默认采用DSA）)
-keystore：指定密钥库的名称(产生的各类信息将不在.keystore文件中)，可指定路径，例如：D:\keys\server.jks。
-validity：证书的有效期，单位：天。
A、输入keystore密码：此处需要输入大于6个字符的字符串。
B、“您的名字与姓氏是什么？”这是必填项。
C、你的组织单位名称是什么？”、“您的组织名称是什么？”、“您所在城市或区域名称是什么？”、“您所在的省/市/自治区名称是什么?”、“该单位的两字母国家代码是什么？”可以按照需要填写也可以不填写直接回车，在系统询问“正确吗？”时，对照输入信息，如果符合要求则使用键盘输入字母“y”，否则输入“n”重新填写上面的信息。
D、输入<bwkt>的密钥口令，这项较为重要，会在tomcat配置文件中使用，建议输入与keystore的密码一致，设置其它密码也可以，完成上述输入后，直接回车则在你在第二步中定义的位置找到生成的文件。
接下来利用server.jks来签发证书：
C:\Users\bwkt>keytool -export -alias server -file server.cer -keystore server.jks
配置Tomcat
找到tomcat/conf/sever.xml文件，并以文本形式打开。
找到端口为8443的标签，修改为：
<Connector SSLEnabled="true" acceptCount="100" clientAuth="true" disableUploadTimeout="true" enableLookups="true" keystoreFile="C:\Users\bwkt\server.jks" keystorePass="123456" maxSpareThreads="75" maxThreads="200" minSpareThreads="5" port="8443" protocol="org.apache.coyote.http11.Http11NioProtocol" scheme="https" secure="true" sslProtocol="TLS" />
注：
keystoreFile：jks文件存放路径
keystorePass：生成证书时候的密码
测试
启动Tomcat服务器，在浏览器中输入 https://localhost:8443/ ，浏览器提示下图即为成功。
注：上面生成的server.cer是为Android客户端准备的。
单项认证--Android端
准备证书
在Android客户端启动的时候在Application中设置证书信息
public class MyApplication extends Application {
@Override
public void onCreate() {
super.onCreate();
try {
// 证书放在assets文件夹中
OkHttpClientManager.getInstance().setCertificates(new InputStream[]{getAssets().open("server.cer")});
} catch (IOException e) {
e.printStackTrace();
}
OkHttpClientManager.getInstance().getOkHttpClient().setConnectTimeout(100000, TimeUnit.MILLISECONDS);
}
}也可以通过命令获取到字符串：
C:\Users\bwkt>keytool -printcert -rfc -file server.cer
代码：
public class MyApplication extends Application {
private static final String SERVER_CER = "-----BEGIN CERTIFICATE-----\n"
+ "MIIDSTCCAjGgAwIBAgIEd05HCTANBgkqhkiG9w0BAQsFADBVMQswCQYDVQQGEwJjbjELMAkGA1UE\n"

+ "-----END CERTIFICATE-----";
@Override
public void onCreate() {
super.onCreate();
try {
// 证书放在assets文件夹中
// OkHttpClientManager.getInstance().setCertificates(new InputStream[]{getAssets().open("server.cer")});
// 根据证书生成的字符串设置证书信息
OkHttpClientManager.getInstance().setCertificates(new InputStream[]{new Buffer().writeUtf8(SERVER_CER).inputStream()});
} catch (IOException e) {
e.printStackTrace();
}
OkHttpClientManager.getInstance().getOkHttpClient().setConnectTimeout(100000, TimeUnit.MILLISECONDS);
}
}准备证书的核心代码如下：
1.设置OkHttpClient主机认证。
mOkHttpClient.setHostnameVerifier(new HostnameVerifier() {
@Override
public boolean verify(String hostname, SSLSession session) {
return true;
}
});2.设置证书信息
/**
* 设置证书信息
* @param certificates
* @param bksFile
* @param password
*/
public void setCertificates(InputStream[] certificates, InputStream bksFile, String password) {
try {
TrustManager[] trustManagers = prepareTrustManager(certificates);
KeyManager[] keyManagers = prepareKeyManager(bksFile, password);
SSLContext sslContext = SSLContext.getInstance("TLS");
sslContext.init(keyManagers, new TrustManager[] { new MyTrustManager(chooseTrustManager(trustManagers)) },
new SecureRandom());
mOkHttpClient.setSslSocketFactory(sslContext.getSocketFactory());
} catch (NoSuchAlgorithmException e) {
e.printStackTrace();
} catch (KeyManagementException e) {
e.printStackTrace();
} catch (KeyStoreException e) {
e.printStackTrace();
}
}
/**
* 准备所信任的服务器证书
* @param certificates
* @return
*/
private TrustManager[] prepareTrustManager(InputStream... certificates) {
if (certificates == null || certificates.length <= 0){
return null;
}
try {
CertificateFactory certificateFactory = CertificateFactory.getInstance("X.509");
KeyStore keyStore = KeyStore.getInstance(KeyStore.getDefaultType());
keyStore.load(null);
int index = 0;
for (InputStream certificate : certificates) {
String certificateAlias = Integer.toString(index++);
keyStore.setCertificateEntry(certificateAlias, certificateFactory.generateCertificate(certificate));
try {
if (certificate != null){
certificate.close();
}
} catch (IOException e) {
}
}
TrustManagerFactory trustManagerFactory = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
trustManagerFactory.init(keyStore);
TrustManager[] trustManagers = trustManagerFactory.getTrustManagers();
return trustManagers;
} catch (NoSuchAlgorithmException e) {
e.printStackTrace();
} catch (CertificateException e) {
e.printStackTrace();
} catch (KeyStoreException e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
return null;
}
/**
* 准备服务器信任的客户端的证书
* @param bksFile
* @param password
* @return
*/
private KeyManager[] prepareKeyManager(InputStream bksFile, String password) {
try {
if (bksFile == null || password == null) {
return null;
}
// Android默认的是BKS格式的证书
KeyStore clientKeyStore = KeyStore.getInstance("BKS");
clientKeyStore.load(bksFile, password.toCharArray());
KeyManagerFactory keyManagerFactory = KeyManagerFactory.getInstance(KeyManagerFactory.getDefaultAlgorithm());
keyManagerFactory.init(clientKeyStore, password.toCharArray());
return keyManagerFactory.getKeyManagers();
} catch (KeyStoreException e) {
e.printStackTrace();
} catch (NoSuchAlgorithmException e) {
e.printStackTrace();
} catch (UnrecoverableKeyException e) {
e.printStackTrace();
} catch (CertificateException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
return null;
}
测试
String url = "https://192.168.0.163:8443/";
new OkHttpRequest.Builder().url(url).get(
new MyResultCallback<String>() {
@Override
public void onError(Request request, Exception e) {
Log.e(TAG, "onError" + e.getMessage());
textView.setText(e.getMessage());
}注：只是获取的页面Html字符串。
双向认证--服务器配置
生成客户端证书
按照生成证书的方式，再生成一对这样的文件，我们命名为:client.jks，client.cer。
配置服务器
将端口为8443的标签，修改为：
<Connector SSLEnabled="true" acceptCount="100" clientAuth="true" disableUploadTimeout="true" enableLookups="true" keystoreFile="C:\Users\bwkt\server.jks" keystorePass="123456" truststoreFile="C:\Users\bwkt\client.jks" truststorePass="123456" maxSpareThreads="75" maxThreads="200" minSpareThreads="5" port="8443" protocol="org.apache.coyote.http11.Http11NioProtocol" scheme="https" secure="true" sslProtocol="TLS" />
注：
truststoreFile：信任证书的文件路径
truststorePass：信任证书的秘密
测试
启动Tomcat服务器，在浏览器中输入 https://localhost:8443/ ，浏览器提示下图即为成功。
双向认证--Android端
生成Android所需的bks格式的证书
由于Java平台默认识别的是jks格式证书，Android默认识别的是bks格式证书，所有要将jks格式的证书转换成bks格式的证书。
步骤如下：
解压后，里面包含portecle.jar文件，双击portecle.jar即可打开GUI界面。
导入证书
点击
打开之前生成的jks文件。
输入密码：
成功打开。
转换证书
点击Tools-->Change keystore Type-->BKS。
输入密码，成功提示如下：
保存证书
Ctrl+s
准备证书
在Android客户端启动的时候在Application中设置证书信息
public class MyApplication extends Application {
private static final String SERVER_CER = "-----BEGIN CERTIFICATE-----\n"
+ "MIIDSTCCAjGgAwIBAgIEd05HCTANBgkqhkiG9w0BAQsFADBVMQswCQYDVQQGEwJjbjELMAkGA1UE\n"
