SSL in sharded environment

I have a sharded environment with 3 shards and one config server and I have only valid certificate.

I have to enable ssl to encrypt connections. 

How will ssl work in sharded cluster? I didn't see any document related to this. 

I am using mongo 2.6.5. 

How can we setup ssl in it?

This should get you on your way.

http://docs.mongodb.org/manual/tutorial/configure-ssl/

This doc doesn't tell how ssl will work in sharded environment.

But it says.

This document helps you to configure MongoDB to support SSL. MongoDB clients can use SSL to encrypt connections to mongod and mongos instances.

So that covers both sharded and replica set clustering.
