comment Using VPN in the UAE - safe or trackable?
You definitely need to expand your question here. This, however, probably already answered the question: security.stackexchange.com/questions/73816/…

1e100 = 1 googol. 1e100.net is Google's domain.

comment Two-way encryption that can be nested?
Couldn't A or B be a "man in the middle"? Also, I'm a little confused by the use of "decode" and "reverse" when talking about encryption. Could you clarify this, perhaps using "decrypt" where appropriate?

comment Storing AES password for verification
No no, 2^123.4 is a good number! Of course, if you want your system to be "theoretically good", you wouldn't want to use MD5, but one with a better reputation (SHA-2/3). That said, I don't really see why you need the hash. You could just try decrypting the data. If it fails, the password's obviously wrong?

comment start point into cryptography and encryption
I have not read it, sorry. For a beginner it might be more motivating to "go easy first", especially if you are not too comfortable with the mathematics. Some books seem to throw the reader directly into maths, while others (like the one I recommended) provide a basic introduction to subsitutions and permutations, historic ciphers, etc. which at least for me was a comfortable introduction. You could always try the Cryptography chat room: chat.stackexchange.com/rooms/784/cryptography

You're right. Sorry about that. I think I tried to be of some sort of help that turned out not to be that valuable ;).

comment Is it safe to store public key encrypted password in the Mobile Device for authentication purposes?
If an attacker can get to the encrypted password and send it to the server without knowing the password, it won't help much. It's still a static shared secret.

Just some language laundry. Pedantic me.

revised Communicate between two sites both with SSL
I think we're moving closer to authentication as a topic here. Really want to remove the SSL part also.
