 The Secure File Transfer System is designed to facilitate secure file transfers between clients and a server. It allows clients to register in a database, exchange encryption keys, and securely send files to the server. The system operates in a client-server architecture and attempts to ensure data confidentiality and integrity during file transmission.

 The communication protocol is binary and runs over TCP. All numerical fields are represented as unsigned values in little-endian format. The protocol supports requests and responses between clients and the server. Messages can contain a "payload" field for various content.
