rassh

SSH client for Android built on OpenSSH and LibreSSL, with its own terminal emulator and extra keys for Unix work

An SSH client for Android built around the real OpenSSH ssh(1).

The app ships OpenSSH 10.5p1 linked against LibreSSL 4.3.2, runs ssh on a pseudo-terminal and draws it with its own xterm compatible terminal emulator. There is no SSH reimplementation: what works with ssh on a Unix box works here, including ~/.ssh/config.

Targets Android 17 (API 37), runs on Android 13 (API 33) and later.

On Android 17 the app asks for the local network permission at start: without it, hosts on the LAN (RFC 1918, CGNAT and link-local addresses) cannot be reached. Hosts reached through a VPN or the mobile network and port forwards on 127.0.0.1 do not need it.

Features OpenSSH 10.5p1 ssh and ssh-keygen built with LibreSSL 4.3.2 Extra keys row above the soft keyboard: ESC / | - HOME ↑ END PGUP on the first row, TAB CTRL ALT ~ ← ↓ → PGDN on the second. CTRL and ALT apply to the next key, typed or tapped. Arrows and page keys repeat while held. Saved hosts, stored as Host blocks of ~/.ssh/config. Host name, user, port, identity file, local, remote and dynamic forwards are editable, any other ssh_config(5) option can be added per host. Unrelated parts of the file (comments, Host *, Match) are kept. Quick connect with plain ssh arguments, e.g. -p 2222 me@example.org Key management: generate ed25519, ecdsa, rsa or mldsa44-ed25519 keys with ssh-keygen (passphrases are asked in a terminal), import private keys, show, copy or share public keys Several sessions at once, kept alive by a foreground service 256 colors and 24 bit color, alternate screen, scroll regions, wide characters, DEC line drawing, bracketed paste Scrollback with a swipe (in full screen programs a swipe sends the cursor keys), pinch to change the font size, long press to select and copy DejaVu Sans Mono bundled, as some vendor themes replace the system monospace font with a proportional one Hardware keyboards: arrows, Home, End, Page Up/Down, Insert, Delete, F1 to F12, Ctrl and Alt
