Diffie Hellman Elliptic Curve Key exchange automated Encrypting system using AES

DHECC

Diffie Hellman Elliptic Curve Key exchange automated Encrypting system using AES. This was a fun side project to get to play with encryption and practice Python.

Built With

• PyCrypto - Used Encryption Library

How To Use

First add the Imports.

import Encryption
import os # optional if you want to generate your own keys.

Next both partys create a Random key that is 32 bytes long.

random_key1 = os.urandom(32) # os random provides a more securely generated value.
random_key1f = int(("".join("{:02x}".format(ord(c)) for c in random_key1)), 16)

# party 2
random_key2 = os.urandom(32)
random_key2f = int(("".join("{:02x}".format(ord(c)) for c in random_key1)), 16)

After this the both partys making use of this will instantiate the AESCipher class in Encryption and pass the randomly generated key to it.

# party 1 
party1 = Encryption.AESCipher(random_key1f)

# party 2
party2 = Encryption.AESCipher(random_key2f)

Once this is done both partys will then obtain their public keys and send them to each other.

# party 1 
party1_pubKey = party1.getPubKey()

# party 2 
party2_pubKey = party2.getPubKey()

# party 1 
party1.DHEC(party2.getPubKey())

## party 2
party2.DHEC(party1.getPubKey())

After this then both partys are able to start encrypting

ent1 = part1.encrypt("howdy" + " " + 128*",")
print(part2.decrypt(ent1))

ent2 = part2.encrypt("howdy2")
print(part1.decrypt(ent2))
