一、单向握手

1、用eclipse运行的时候报NoSuchAlgorithmException的错。将eclipse的JRE删除再重新导入本地的JRE就解决了。应该是缺失一些JDK的jar导致。

上面的程序使用JDK7将导致自己签名的证书验证失败，报的错误和下面的请求百度报的错相同。使用JDK6成功。这是JDK7的一个bug引起的：http://bugs.java.com/bugdatabase/view_bug.do?bug_id=7018897
针对于JDK7的这个bug需要使用下面的代码：

该程序在JDK6运行成功。
使用X509TrustManager可以动态的改变握手时验证证书的行为。可以利用这点来动态的导入证书，而不是需要手动的导入证书。 具体的用法参见下面的博客：
