Create a new instance of the DiffieHellmanGroup1SHA1
algorithm. The data is a Hash of symbols representing information required by this algorithm, which was acquired during earlier processing.

Perform the key-exchange for the given session, with the given data. This method will return a hash consisting of the following keys:
-
:session_id
-
:server_key
-
:shared_secret
-
:hashing_algorithm
The caller is expected to be able to understand how to use these deliverables.
