EP124: How does SSH work?
SSH (Secure Shell) is a protocol for securely connecting to remote machines over an unsecured network. It encrypts connections and offers various authentication and data transfer mechanisms. SSH-2, standardized by the IETF, features three main layers: Transport, Authentication, and Connection. The Transport Layer ensures secure communication, the Authentication Layer verifies user identities, and the Connection Layer multiplexes encrypted communication into multiple channels.
