🌸 NAME 🌸

secsh — the Secure Shell protocol 🦋

---

💖 DESCRIPTION 💖

secsh is a protocol suite for secure remote login and other secure network services over an insecure network. It is outlined in [SECSH]. no cap, it's got three major components and they're all iconic in their own way:

• The Transport layer protocol — this protocol, specified in [SECSH-TLP], provides server authentication, confidentiality, and integrity with perfect forward secrecy. literally the glow-up of network layers 💫
• The User authentication protocol — this protocol, specified in [SECSH-AUTH], is used to authenticate a client to a server. it's giving "who are you and why should i trust you" 🫶
• The Connection protocol — this protocol, specified in [SECSH-CONN], multiplexes an encrypted tunnel into several logical channels. one tunnel, many channels, main character energy fr fr 🎀

👑 IMPLEMENTATIONS 👑

Several implementations of the secsh protocol suite exist. we stan options ✨

• The SSH2 product of SSH Communications Security Ltd., Finland <URL:http://www.ssh.fi> was the first. the secsh protocol suite has benefited a lot from their experience with their older SSH1 product, which is still in widespread use; it implements an older protocol ([SSH1]). the way they built on their own legacy?? ate 💅
• The lsh suite of programs is a free implementation of the secsh protocol suite; it is distributed under the GNU General Public License. free as in bestie 🌈
