Java HttpsURLConnection和TLS 1.2 [英] Java HttpsURLConnection and TLS 1.2

问题描述

我读过一篇文章，HttpsURLConnection将透明地协商SSL连接.

I read in an article that HttpsURLConnection will transparently negotiate the SSL connection.

官方文件说:

此类使用HostnameVerifier和SSLSocketFactory.这两个类都有默认的实现. ^{[ 1 ]}

This class uses HostnameVerifier and SSLSocketFactory. There are default implementations defined for both classes. ^[1]

这意味着一旦您打开与...的连接

Does that mean once you open a connection with

httpsCon = (HttpsURLConnection) url.openConnection();

已经对SSL/TLS进行了加密，而没有任何麻烦吗?

It is already SSL/TLS encrypted without any more hassle?

如何查看和设置标准实施的TLS版本? (应该是Java 8的TLS 1.2和Java 7的TLS 1.0)

How can I view and set the TLS version for the standard implementation? (Should be TLS 1.2 for Java 8 and TLS 1.0 for Java 7)

推荐答案

您将必须创建一个SSLContext来设置Protocoll:

在 Java 1.8 中:

You will have to create an SSLContext to set the Protocoll:

in Java 1.8:

 SSLContext sc = SSLContext.getInstance("TLSv1.2");
 // Init the SSLContext with a TrustManager[] and SecureRandom()
 sc.init(null, trustCerts, new java.security.SecureRandom()); 

在 Java 1.7 中:

 SSLContext sc = SSLContext.getInstance("TLSv1");
 // Init the SSLContext with a TrustManager[] and SecureRandom()
 sc.init(null, trustCerts, new java.security.SecureRandom());

然后，您只需将 SSLContext 设置为 HttpsURLConnection :

then you just have to set the SSLContext to the HttpsURLConnection:

httpsCon.setSSLSocketFactory(sc.getSocketFactory());

那应该做把戏.
