Your company, SecureTech Inc., is planning to transmit some sensitive data over an unsecured communication channel. As a cyber security expert, you decide to use symmetric key encryption to protect th

Implementing SSL certificates primarily provides identity verification and establishes a secure channel via TLS, but the underlying key exchange often leverages protocols like Diffie-Hellman or RSA within TLS.

The Diffie-Hellman protocol is specifically designed for securely exchanging cryptographic keys over a public, unsecured communication channel, enabling two parties to agree on a shared secret key that can then be used for symmetric encryption.

HTTPS is an application-layer protocol for secure web communication using SSL/TLS, but it is not a key exchange protocol itself; rather, it uses key exchange protocols as part of its security mechanism.

Utilizing SSH is for secure remote logins and command execution, not a general-purpose protocol for symmetric key exchange in the context of data transmission between arbitrary applications.
