tinysshd is a minimalist SSH server that prioritizes secure cryptography with state-of-the-art algorithms like ssh-ed25519 and chacha20-poly1305. It excludes older and unsafe crypto methods and features like password authentication, SSH1 protocol, and port forwarding. The project timeline shows a progression from experimental to beta releases, indicating readiness for production use. The current release includes post-quantum cryptography and detailed instructions on how to run the server using various methods like TCP server, Busybox, inetd, and systemd. This unique server avoids dynamic memory allocation and offers a streamlined, secure SSH experience.
