Complete TLS Workflow in Golang Made Simple: Full Process Explained
- The TLS handshake process is crucial for establishing secure communication between clients and servers.
- It starts with the Client Hello message, containing supported TLS versions, cipher suites, and a Client Random.
- The Server Hello message includes the selected TLS version, cipher suite, Server Random, and the server's digital certificate.
- Certificate Verification ensures the server's certificate validity and correctness.
- Pre-Master Secret Generation involves creating a secret using the server's public key for encryption.
- Master Secret Derivation uses Client Random, Server Random, and Pre-Master Secret to generate session keys.
- Session Keys are created for encryption and integrity checks, followed by exchanging Finished messages by the client and server.
- All subsequent data transfer is encrypted using session keys, ensuring secure communication.
- A GoLang server implementation captures ClientHello messages for analysis by periodically exporting details to a JSON file.
- The server code includes functions for handling connections, collecting ClientHello information, and serving TLS connections.
