SSH Host Vault is a Linux alternative to Termius for organising SSH hosts. Disclaimer: This project is an independent open-source tool and is not affiliated with, sponsored by, or endorsed by Termius Corporation.

What it really does: • Encrypted vault: hosts, passwords/key passphrases, snippets and port-forward rules are stored in one file encrypted with ChaCha20-Poly1305 (RFC 8439, pure-Python implementation verified against the RFC test vectors); the key is derived from your master password with scrypt (N=2^15, r=8, p=1). Encrypted export / import with a separate password. • Host groups and tags, search, TCP/banner reachability test with measured ms. • Import concrete Host entries (incl. Include, LocalForward/DynamicForward) from your real ~/.ssh/config. • Connect: launches the real OpenSSH ssh client in a pseudo-terminal shown in a built-in VT100 terminal (basic, no colours). Stored passwords / passphrases are typed automatically at the prompt. • Snippets: run commands on a host over ssh and see the output. • Port forwarding rules (-L / -R / -D) started as real ssh processes. • known_hosts viewer for ~/.ssh/known_hosts with SHA256 fingerprints, hashed-entry lookup, ssh-keyscan and trust-on-confirm.

Snap notes: reading ~/.ssh (config, keys, known_hosts) needs the ssh-keys interface: sudo snap connect ssh-host-vault:ssh-keys. Inside the snap ~/.ssh is read-only, so newly accepted host keys are written to the app's own known_hosts file. The built-in terminal is a VT100 subset; complex full-screen programs may render imperfectly (use "Copy ssh command" for your terminal).
