# KosSSH Mobile

Android SSH mobile client MVP, Kotlin + Android Views + JSch.

## SDK / Build

- `compileSdk = 37`
- `targetSdk = 37`
- `minSdk = 26`
- Android Gradle Plugin: `9.4.0`
- Gradle: `9.6.0`
- Java: 17
- Android Studio: use a version that supports API 37 (Android Studio Panda 3 or newer).

Android 17 / API 37 requires apps targeting API 37+ that connect to LAN devices to declare and request `ACCESS_LOCAL_NETWORK` at runtime. KosSSH requests it when the user starts an SSH connection.

## Features

- SSH-2 interactive PTY (`xterm-256color`)
- Password authentication
- ANSI SGR basic colors + bold
- Custom terminal font size
- GitHub Dark theme
- CTRL dialog, ESC, TAB and arrow keys
- Android software keyboard integration
- Scrollback buffer

## Security note

The current MVP still disables strict host-key verification in `SshClient.kt` to simplify initial testing. Do not ship this configuration to production. The next hardening step should add a persistent known-hosts store and explicit host-key verification, followed by encrypted server profiles/private-key storage.

## Android 17 note

Android 17 (API 37) adds a runtime local-network permission. For SSH servers on a LAN, the app asks for `ACCESS_LOCAL_NETWORK` immediately before the connection is opened.
