Android 加密传输(SSL),双向认证 笔记

工作需要使用到 Android  加密传输(SSL),双向认证 ,因为未使用过,所以搜索了总结了一下相关知识,并整理作为笔记

                   Android实现ssl双向验证

搜索的时候关于SSL+http 的解释有很多,不做细说,本文只记录如何实现,包括证书制作、myeclipse服务部署以及Android端代码。

证书制作

打开cmd命令窗口

1、生成客户端keystore

keytool -genkeypair -alias E:\sslhttpTest\keystool\client -keyalg RSA -validity 3650 -keypass 123456 -storepass 123456 -keystore E:\sslhttpTest\keystool\client.jks

注:此处 E:\sslhttpTest\keystool\client  是本人手误 只需输入 client 即可,alias 无需路径

2、生成服务端keystore

keytool -genkeypair -alias server -keyalg RSA -validity 3650 -keypass 123456 -storepass 123456 -keystore E:\sslhttpTest\keystool\server.keystore

3、导出客户端证书

keytool -export -alias E:\sslhttpTest\keystool\client -file E:\sslhttpTest\keystool\client.cer -keystore E:\sslhttpTest\keystool\client.jks -storepass 123456

4、导出服务端证书

keytool -export -alias server -file E:\sslhttpTest\keystool\server.cer -keystore E:\sslhttpTest\keystool\server.keystore -storepass 123456

5、重点:证书交换

将客户端证书导入服务端keystore中,再将服务端证书导入客户端keystore中, 一个keystore可以导入多个证书,生成证书列表。

生成客户端信任证书库(由服务端证书生成的证书库):

keytool -import -v -alias server -file E:\sslhttpTest\keystool\server.cer -keystore E:\sslhttpTest\keystool\truststore_s_for_c.jks -storepass 123456

将客户端证书导入到服务器证书库(使得服务器信任客户端证书):

keytool -import -v -alias E:\sslhttpTest\keystool\client -file E:\sslhttpTest\keystool\client.cer -keystore E:\sslhttpTest\keystool\client_for_server.keystore -storepass 123456

6、生成Android识别的BKS库文件

下载地址: protecle.jar 百度网盘下载地址

运行protecle.jar将client.jkstruststore_s_for_c.jks分别转换成client.bkstruststore_s_for_c.bks ,然后放到android客户端的assert目录下

File -> open Keystore File -> 选择证书库文件 -> 输入密码 -> Tools -> change keystore type -> BKS -> save keystore as -> 保存即可

7、配置Tomcat服务器(可选)

找到Tomcat安装目录 conf\server.xml文件,配置8443端口

注:

可以不配置tomcat ,只需配置 eclipse 的工程目录中的对应的server.xml文件 E:\eclipsework\.metadata\.me_tcat7\conf\server.xml(我的工程目录在E:\eclipsework 根据实际情况找路径) 。如果 eclipsework\.metadata\.me_tcat7 的目录下没有 conf 目录,需要新建conf文件夹然后将 tomcat 安装目录 conf\server.xml文件复制过来,然后启动myeclipse的服务,会报错 根据报错删除

即可,配置 server.xml 的端口

Android 端配置
