TermLink: SSH for AI Coding

TermLink turns your iPhone into a compact SSH companion for AI coding, server checks, and remote file handoff.

Connect to your own SSH host with a password, an imported ed25519/ECDSA key, or a key pair generated in the app, copy the public key, and keep the setup steps close to the terminal. Upload screenshots or photos over SCP, then pass the remote path to Codex, Claude Code, or another AI coding workflow without retyping it.

The local workspace stays inside the iOS app sandbox. Built-in commands cover file navigation, JSON formatting, Base64 encode/decode, and JavaScriptCore-backed Node-compatible snippets for safe learning and small experiments.

Key features:
- SSH profile setup: password authentication (stored only in this device's Keychain), import of existing OpenSSH ed25519/ECDSA private keys, including passphrase-protected keys (the passphrase is never stored)
- 3-step ed25519 key setup: create, register on your server, test the connection. Switch an existing profile to the new key
- Free quick-reply bar: 1, 2, 3, Enter, Esc, y and Shift+Tab in one tap to answer Claude Code and Codex prompts
- Optional Face ID / Touch ID protection for private keys and saved passwords
- Remote shell access from iPhone
- SCP image upload and remote path handoff
- Snippets for frequent SSH commands and AI prompts
- Sandboxed local files and bundled command shims
- JSON formatter, Base64 tools, and JavaScriptCore snippets
- Japanese IME support and app language switching
- Adjustable terminal font size
- Optional Pro themes, multiple tabs, multiple SSH profiles, multiple snippets, and remote path insertion

RSA keys are not supported. Passphrase-protected keys are supported in OpenSSH format (ssh-keygen's default encryption). Password authentication requires PasswordAuthentication to be enabled on the server.

TermLink is built as an SSH companion, a command-line learning tool, and an AI coding handoff surface. It is not a native package manager, an external code store, or a way to run downloaded native executables after review.
