DER input, Integer tag error的异常处理

1、首先我向大家介绍一下我做的东西，发生这个异常的情况。

　　我做的是一个电签的系统，在调用某公司的API生成证书，然后与安证通进行同步证书的任务。

2、问题具体的异常

　　具体异常如下：

　3、解决问题

　　错误的原因是证书的申请是pkcs7格式的生成，但是安证通同步解析用到的是pkcs12，造成编码解码不一致的问题。

　　起初就是jar包的冲突问题，bcprov-jdk15-1.46.jar没有向下兼容bcprov-jdk15-1.43.jar，因为这其中的DERSequence方法的构造方法不同。大家可以自行的下载看看。

　　最后我们是在申请证书之后，用证书去获取这个pfx格式的编码，然后去用安证通同步，这样就解决了这个问题。（因为这是第三方的东西，所以要和第三方进行沟通，他们提供了一个新的方法来获取证书的pfx格式编码）。

　　4、总结

　　遇见jar包冲突的问题，解决的根本方法就是去掉冲突的jar，留下一个我们用到的jar包，否则，就算解决了，项目上线也会有很多的问题的。

　　5、美诗美句

　　少年不识愁滋味，爱上层楼，爱上层楼，为赋新词强说愁。

　　而今识尽愁滋味，欲说还秀，欲说还休，却道天凉好个秋。
