SSL的基础知识

SSL的全称是Secure Socket Layer。它的通信流程如下图所示，客户端与服务端会通过几次通信，通过非对称加密创建出一个加密密钥，用于以后的对称信息加密。

1，客户端明文向服务器打招呼，告诉服务器自己支持的加密算法、随机数A；

2，服务器明文返回给客户端自己的证书和另外一个随机数B；

3，客户端验证收到的证书。验证通过则使用这个证书的公钥加密一个密码发送给服务器；

4，服务器通过自己的私钥解密客户端发送过来的密码；

5，服务器使用这个密码进行对称加密通信。

用-Djavax.net.debug=all跟踪调试，确定对的证书

任何一个环节出错，都可能出现下面的错误：

PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

 

用-Djavax.net.debug=all来开启调试信息的输出，SSL的握手过程一目了然：

 如果遇到了前面的报错信息，首先应该做的就是到这里来看看服务器给客户端发送的到底是个什么证书！知道是什么证书之后，尝试获取到这个证书，导入到本地就行了。

正确地导入证书

服务器办法给我们的cer证书文件需要导入到keystore文件中，Java才能识别。

keytool工具实现了对keystore文件中的证书进行曾删查功能。

证书管理

增加（导入证书）

keytool -import -noprompt -trustcacerts -alias test -file  D:\certs\some.cer -keystore cacerts -storepass changeit

 

-keystore：指定证书导入到的文件位置，文件不存在时会自动创建，存在时会追加

-file：指定导入的cer文件

-storepass：指定keystore文件的访问密码

-alias：指定别名，其实可以理解为ID，别名不能重复，删除的时候也依靠它

查询

keytool -list -keystore cacerts |findstr /s test

 因为结果可能很多，这里用windows的findstr来过滤。

删除

keytool -delete -alias test -keystore cacerts

 

证书识别

Java程序对受信证书的查找顺序是：

1,javax.net.ssl.trustStore  

就是System.setProperty("javax.net.ssl.trustStore","D:\\cacert.keystore");活着通过JVM参数指定：-Djavax.net.ssl.trustStore=D:\cacert.keystore。

2,JAVA_HOmE\jre\lib\security\jssecacerts

默认没有jssecacerts，一般把cacerts复制成jssecacerts，然后再使用keytool来修改它。jsse的全称是Java Secure Socket Extension。

3,JAVA_HOmE\jre\lib\security\cacerts

 通常情况下不就建议通过-Djavax.net.ssl.trustStore=D:\cacert.keystore来直接修改keystore文件的位置，因为这样会造成系统中其他模块可能找不到自己对应的证书了。推荐使用jssecacerts。我们需要什么证书直接往这个位置导就行了。程序不需要做调整。

 

其他注意事项

System.setProperty("javax.net.ssl.trustStore",..)可能不会生效

写一个JUnit单元测试可以这么改：

但是在Spring的Service中动态修改就不见得会生效了。你虽然动态调整了System的属性，但是别人用不用就不确定了。

https://stackoverflow.com/questions/271506/why-cant-system-setproperty-change-the-classpath-at-runtime

使用JVM参数强制指定keystore

 用JVM参数的形式就比上面这种方式更有效，程序肯定会使用这个参数指定位置的keystore。

-Djavax.net.ssl.trustStore=C:\Java\jre\lib\security\jssecacerts
-Djavax.net.ssl.trustStorePassword=changeit

 

后话

密码和安全相关的主体确实太有意思了，应该专题研究一下，什么是PKI、什么是X.509，要扫清盲点，知其所以然，这样才能在遇到异常时知道那个环节出了问题。 

 

个人学习总结，有不对之处还望赐教。
