The point of Diffie-Hellman is that nothing in public domain can be combined in any way to get our secret key.

Truth is Diffie-Hellman is never used by itself for the following reasons:
- By default it provides no defense against man-in-the-middle attacks.
- Discrete Logarithms problem is very computationally expensive problem, but dedicated organizations like NSA or other security agencies of world may have more than enough resources to attempt bruteforce.

Discrete Logarithms problem is very computationally expensive problem, but dedicated organizations like NSA or other security agencies of world may have more than enough resources to attempt bruteforce.

I will cover these problems, especially the man-in-the-middle aspect of key exchanges in a post. If you are interested, you can use these keywords to do your own research.
