Explanation

Telnet is a legacy remote access protocol that transmits all data-including credentials and commands-in plaintext, making it trivially interceptable. SSH (Secure Shell) is its direct, secure replacement: it provides the same remote terminal access functionality but encrypts the entire session using strong cryptography. HTTPS secures web traffic (HTTP), not terminal sessions. HMAC (Hash-based Message Authentication Code) is a mechanism for verifying message integrity and authenticity, not a remote access protocol. GPG (GNU Privacy Guard) is used for encrypting and signing files and emails, not for interactive remote sessions.
