How do I configure my ssh client to forward X connections securely?
I use this SSH Client for Android, it only uses updated, current and secure ciphers, and this is very important, since not all SSH is the same, many SSH protocols on the market use outdated and old ciphers, which makes SSH old, which is equivalent to insecure, easily hacked SSH. They also have a blog with answers to the most relevant questions, I think it can be useful for you.
