Will SSLContext.getInstance(“TLS”) supports TLS v1.1 and TLS v1.2 also?

问题

In my java Code i am creating one instance of SSL Context using command

SSLContext ctx = SSLContext.getInstance("TLS");

But in my tomcat server i am setting TLSv1.2 and i am getting handshake error.

How we can support all the TLS protocols using this method like in cpp we have SSLV23 client method which will support all protocols.

回答1:

To use TLSv1.2 try to use below code:

SSLContext sslContext = SSLContext.getInstance("TLSv1.2");
sslContext.init(null, null, null);
