# KosSSH Mobile

Android SSH mobile client starter project with interactive PTY, ANSI color rendering, custom terminal font size, keyboard helper keys, and password authentication.

## Build

Open this folder in Android Studio (Ladybug or newer) and let Gradle sync. Then run on an Android 8.0+ device/emulator.

Or from a machine with Gradle/Android SDK configured:

```bash
./gradlew assembleDebug
```

APK output:
`app/build/outputs/apk/debug/app-debug.apk`

## Current features

- SSH shell over JSch (SSH-2)
- PTY `xterm-256color`
- Interactive keyboard via InputConnection
- ANSI SGR basic 16-color + bright color + bold
- Adjustable monospace font size
- Dark terminal theme
- Ctrl+A-Z helper
- Tab/Esc/arrow helper buttons
- Host/port/user/password fields

## Important production hardening

This is a functional MVP, not yet a production-grade SSH client. Before shipping, replace `StrictHostKeyChecking=no` in `SshClient.kt` with persistent known-hosts / host-key fingerprint verification, add encrypted profile storage with Android Keystore, private-key authentication, SFTP, terminal resize (`windowChange`), robust VT100/VT220/VT420 parsing, selection/copy, scrollback UI, and connection lifecycle handling.
