About:
SSH3 is a modern implementation of the SSH protocol that leverages HTTP/3 and QUIC for significantly faster connection establishment and data transfer. It provides a richer user experience with features like native JSON-based authentication flows and improved multiplexing. This tool aims to replace traditional SSH by utilizing modern web transport standards for enhanced performance and security.
Key Features:
  • Uses HTTP/3 and QUIC for low-latency, multiplexed transport
  • Faster connection setup compared to traditional SSH
  • JSON-based authentication API for modern identity providers
  • Full compatibility with existing SSH keys and infrastructure
Use Cases:
  • Accelerating file transfers and remote commands over high-latency networks
  • Integrating SSH authentication with modern web-based identity systems
  • Securing remote access in environments where legacy SSH ports are restricted
Alternatives:
  • OpenSSH – The standard, ubiquitous SSH implementation using TCP, which can be slower on lossy networks.
  • Mosh (Mobile Shell) – Optimizes for intermittent connectivity but does not use the HTTP/3 standard.
