Simple PFS-P2P-LAN-Chat

Simple PFS-P2P-LAN-Chat

• Encrypted Messages with PFS (using TLS)
• File Transfers
• Only Peers with a matching Password can join
• Peer to Peer
• Peer detection via UDP broadcasts
• Uses only Python (that uses OpenSSL)

But why?

This Chat is for these poor Souls who need to work on a local Network with a college while being under survailance by the customer.
