SSH3: Faster and rich secure shell using HTTP/3 (github.com)

Article summary

SSH3 is a new protocol that aims to improve the performance and security of secure shell connections by leveraging HTTP/3 and QUIC. It claims to offer faster session establishment and new features such as UDP port forwarding and keyless secure user authentication. The protocol is still experimental and not yet ready for production use. It is being developed as an open-source project to facilitate community feedback and analysis.

• Performance optimization
• Experimental technology

What commenters say

• The new protocol's faster connection establishment is a significant improvement, especially for automation use cases where connection setup time is crucial.
• The use of HTTP/3 and QUIC can help reduce head-of-line blocking and improve performance over high-latency links.
• Some users are skeptical about the need for a new protocol, citing the effectiveness of existing solutions like mosh for high-latency connections.
• The experimental nature of SSH3 raises concerns about its security and readiness for production use, and more testing and review are needed before it can be widely adopted.
• The protocol's ability to multiplex multiple streams over a single connection can help improve performance, but it may not be a significant advantage for all use cases.
• The development of SSH3 as an open-source project is a positive step, as it allows for community feedback and analysis to help improve the protocol.
