AES-128 encryption with Diffie-Hellman algorythm for key exchange

Simple implemention of AES-128 with Diffie-Hellman algorythm for key exchange between client and server (socket)

Getting Started

The program require some initial paramaters which can be produced by Openssl

Prerequisites

Install Openssl from here

then install pycrypto:

pip install pycryptodome

Running the tests

produce initial parameters with open ssl

with this command in Openssl, two public parameters for DH algorithm will produce and with next command we can see them.

dhparam -out dhp.pem 128
pkeyparam -in dhp.pem -text

then we can create private key for both sides and see the private keys

genpkey -paramfile dhp.pem -out dhkey_client.pem
genpkey -paramfile dhp.pem -out dhkey_server.pem
pkey -in dhkey_client.pem -text -noout
pkey -in dhkey_server.pem -text -noout
