Diffie Hellman key exchange

Question

See more:

I've found out that Microsoft finally implemented diffie-hellman into .net 3.5

Is it possible to do a key exchange with this implementation?

I want to be able to decrypt the secret information from the key exchange data.

Then I want to use the P and G paremeters Wiki...[] to create a key exchange.

I've been looking into this for an hour and msdn isn't quite explaining about this part of .net :sigh:

anybody an idea?:confused:

Did you try anything besides MSDN?

I found this article: Elliptic Curve Diffie-Hellman[^] as the first result in a google search of ".NET Diffie-Hellman.

It looks like it shows you what you're asking.

[Response]
The .Net implementation doesn't appear to directly expose the g an p values, and it doesn't appear that they can be set either. Though you can pass a CngKey

To do a key exchange, you simply pass each other's PublicKey value.

If you want a true implementation, you may want to look at third-party dlls, such as Chilkat which allows for p and g.
