Implementing TLS 1.2 on Android 2.3.3

Question

I have been trying to implement TLS 1.2 on Android. I create an SSLSocket s but when I run s.getSupportedProtocols(), TLS 1.2 is not one of the options. TLSv1 and SSLv3 are supported but TLSv1.2 is not.

In relation to that question, the ciphersuite I need is also not on there (TLS_ECDHE_ECDSA_WITH_AES_256_...)

Any idea on what I could import or do to enable TLSv1.2 and that cipher on android? Is there something I am missing? Any ideas would be helpful! Thanks!

Answer 1

Just for documentation purpose (this question is 3.5 years old) - Android API documentation has a list of supported SSL/TLS per API level, including specific cipher suites: https://developer.android.com/reference/javax/net/ssl/SSLSocket.html

Answer 2

You can't really enable it if it is not there. To add support for TLSv1.2 you need to either add a new JSSE provider (not trivial), or if you only need a socket, probably implement it in native code using OpenSSL. Or simply use JB if you can.
