Looking for Python developer

Hello, it is a small project and i am attaching the basic template. Its a small chat system basically these steps 1-login 2-sign up 3-send invitation to friends 4-accept invitation 5-see list of friends 6-start instant messaging one to one 7-implement security mechanism Example #1 ALice and Bob register themselves in system #2 After registration they need to generate their public key pair in the browser and send their public key pair to the server(it should store in User table, just next to hashed password) User Table- (Id,Username,hashed password,salt,PK...) #3 If Alice wants to start communication, she will start session with Bob if not any. The session will be used to symmetrically encrypt the actual message. For this session key it needs to be encrypted with Bob's public key. You need to attach a signature for this message using Alice's private key #4 Bob will decrypt the session key using Bob's private key. Bob will decrypt the actual message with the session key just decrypted. Finally check the signature Attached is the website template so that you can run server and show corresponding sites with the prepared html pages.
