解决PKIX问题：unable to find valid certification path to requested target【X509TrustManager】
最近，又在网上看了许多关于类似PKIX问题的文章，发现了一种通过X509TrustManager绕过https认证的一种方式，拿了几个网站做例子，果然可以实现！ certification path to requested target */ TrustManager[] trustAllCerts = new TrustManager[] { new X509TrustManager

Android通信安全之HTTPS
缺少相应的安全校验很容易导致中间人攻击，而漏洞的形式主要有以下3种： 自定义X509TrustManager 在使用HttpsURLConnection发起 HTTPS 请求的时候，提供了一个自定义的X509TrustManager 如果不提供自定义X509TrustManager，代码运行起来可能会报异常（原因下文解释），初学者就很容易在不明真相的情况下提供了一个自定义的X509TrustManager，却忘记正确地实现相应的方法 这里引用部分相关代码: TrustManager tm = new X509TrustManager() { public void checkClientTrusted(X509Certificate SSLContext.getInstance("TLSv1","AndroidOpenSSL"); context.init(null, new TrustManager[]{ new X509TrustManager

java HttpsURLConnection 实现https请求
X509证书信任管理器类的实现及应用 在JSSE中，证书信任管理器类就是实现了接口X509TrustManager的类。我们可以自己实现该接口，让它信任我们指定的证书。 接口X509TrustManager有下述三个公有的方法需要我们实现： ⑴ oid checkClientTrusted(X509Certificate[] chain, String authType 图1 部分JSSE类的关系图 假设自己实现的X509TrustManager类的类名为：MyX509TrustManager，下面的代码片断说明了如何使用MyX509TrustManager httpsConn.setSSLSocketFactory(ssf); 这样，HttpsURLConnection对象就可以正常连接HTTPS了，无论其证书是否经权威机构的验证，只要实现了接口X509TrustManager 下面我们来看看实现X509TrustManager的接口实现https请求代码 1、实现X509TrustManager获取SSLSocketFactory [java] view plain
