# SSH Connection Manager (Android, Kotlin + Jetpack Compose) — Bauplan
|
||||
|
||||
## Wichtige Vorbemerkung: 1Password auf Android
|
||||
**Echte native 1Password-SSH-Integration ist auf Android technisch nicht möglich** — der 1Password SSH Agent und die SDKs sind Desktop-only (macOS/Windows/Linux), es gibt keine Kotlin/Java-API und keinen Android-Agent, nur einen offenen [Feature-Request](https://www.1password.community/developers-69/feature-request-android-and-ssh-19991). Du hast dich für **„Nur Datei-Import"** entschieden: Private Keys werden per Storage-Access-Framework importiert, AES-verschlüsselt (Android Keystore) gespeichert. Der praktische 1P-Workflow ist dann: Key auf dem Desktop aus 1Password exportieren → aufs Handy übertragen → in der App importieren. Kein 1Password-Bezug im UI.
|
||||
|
||||
## Stack & Abhängigkeiten (je current stable, 2026)
|
||||
- **Kotlin 2.0+ (K2)**, AGP 8.7+, JDK 17, Compile/Target SDK 35, **Min SDK 26**
|
||||
- **Jetpack Compose** (BOM), Material 3, dunkles Theme, Single-Activity + Navigation-Compose
|
||||
- **Hilt** (DI, via KSP), **Room** 2.6+ (via KSP), Coroutines + Flow
|
||||
- **sshj 0.39.x** — SSH-Verbindung, Auth (Passwort + Public Key), Shell/PTY
|
||||
- **Termux `terminal-emulator`** via JitPack (`v0.118.3`) — VT100/xterm-Emulation (state machine, ANSI-Parsing, Buffer)
|
||||
- **Bouncy Castle** (`bcprov-jdk18on`) — registriert als Provider, damit sshj OpenSSH-/Ed25519-Keys liest
|
||||
- **Android Keystore** — AES-GCM-Schlüssel zur Feldverschlüsselung (Passwörter, private Keys)
|
||||
|
||||
## Architektur (Clean Layering, Paket-Struktur)
|
||||
```
|
||||
core/crypto KeystoreCrypto (AES-GCM Ver-/Entschlüsselung sensitiver Felder)
|
||||
data Room: AppDatabase, Entities (Host, SshKey, Group), DAOs, Repositories, DI
|
||||
domain/model Host, SshKey, Group, AuthMethod (sealed)
|
||||
ssh SshConnectionManager (sshj SSHClient, Auth, Shell), SshSession, KeyLoader, DI
|
||||
terminal SshTerminalBridge, TerminalShell, KeyEncoder, ui/TerminalScreen (Canvas), ViewModel
|
||||
ui theme, nav (AppNavGraph, Routes), hostlist, hosteditor, keylist, keyimport, components
|
||||
```
|
||||
|
||||
## Datenmodell (Room)
|
||||
- **Host**: id, name, hostName, port, userName, groupId?, authType (PASSWORD/KEY), passwordCipher?, keyId?, lastConnected?
|
||||
- **SshKey**: id, name, keyType, fingerprint, privateKeyCipher, hasPassphrase, createdAt
|
||||
- **Group** (optional): id, name, sortIndex — zum Ordnen von Hosts
|
||||
|
||||
## Sicherheits-Workflow
|
||||
1. Key-Import via SAF (`ACTION_OPEN_DOCUMENT`, MIME `*/*`), Datei als String lesen.
|
||||
2. Mit sshj parsen → Typ + Fingerprint bestimmen; ggf. Passphrase abfragen.
|
||||
3. Private Key mit Keystore-AES-GCM verschlüsseln, Ciphertext in Room speichern, Klartext sofort verwerfen.
|
||||
4. Beim Verbinden: entschlüsseln → in den Arbeitsspeicher → sshj laden → verbinden → verwerfen.
|
||||
5. Host-Passwörter analog verschlüsselt.
|
||||
|
||||
## Terminal-Integration (Kernbaustein)
|
||||
Bidirektionale Brücke zwischen **sshj-Shell-Stream** und **Termux-`TerminalEmulator`**:
|
||||
- sshj `Shell` → Output-Bytes in Reader-Thread → `TerminalEmulator.process(bytes)` → aktualisiert `TerminalBuffer`.
|
||||
- Tastatur-Eingabe → `KeyEncoder` (Pfeiltasten etc. → ESC-Sequenzen) → `SshTerminalBridge.write()` → sshj Shell-OutputStream.
|
||||
- `TerminalEmulator` direkt verwendet (nicht `TerminalSession`, das lokale Prozesse startet).
|
||||
- **Renderer**: eigene dünne `Canvas`-Composable, die `TerminalBuffer` rendert — orientiert an Termux' `TerminalRenderer`. Scope: monospaces Raster, 16/256-Farben-Palette, bold/italic/underline/inverse, Cursor, Scrollback, Alternate Screen. Deckt reale Server-Sessions (`vim`, `htop`, Shell) ab; exotisches (Sixel/Maus) bewusst out-of-scope.
|
||||
- IME-Anpassung (sichtbare Soft-Tastatur, Ctrl/Alt/Esc/Tastatur-Erweiterungsleiste) als Bestandteil.
|
||||
|
||||
## UI-Screens (Compose)
|
||||
1. **HostList** — gruppierte Liste, Suche, Connect-Action, Swipe-to-delete; FAB „Host hinzufügen".
|
||||
2. **HostEditor** — Felder für Name/Host/Port/User, Auth-Auswahl (Passwort vs. Key-Auswahl), Group-Zuordnung, „Verbindung testen".
|
||||
3. **KeyList** — Keys mit Fingerprint/Typ, Import-Button, Löschen.
|
||||
4. **KeyImport** — Datei wählen (SAF), Name, Passphrase, Vorschau-Validierung.
|
||||
5. **Terminal** — Fullscreen Canvas-Terminal + Tastaturleiste; Connection-Status, Disconnect.
|
||||
|
||||
## Build-Reihenfolge (Phasen)
|
||||
1. **Scaffold**: Gradle (Version Catalog `libs.versions.toml`), Manifest, Application (Hilt), MainActivity, Theme, Navigation-Gerüst.
|
||||
2. **Daten & Crypto**: Room-Entities/DAOs/DB, Repos, `KeystoreCrypto`, DI-Module.
|
||||
3. **UI CRUD**: HostList, HostEditor, KeyList, KeyImport (SAF + sshj-Parse + Verschlüsselung). Ab hier lauffähiger Manager.
|
||||
4. **SSH-Layer**: `SshConnectionManager` (sshj Connect + Auth Passwort/Key), „Verbindung testen".
|
||||
5. **Terminal**: Brücke + `TerminalEmulator`-Wiring + Canvas-Renderer + Tastatur. End-to-end SSH-Session im Terminal.
|
||||
6. **Robustheit**: Connection-Lifecycle im process-globalen Singleton (überlebt Konfigwechsel), Fehler-/Timeout-Handling, Später: Foreground-Service für echte Hintergrund-Persistenz (als Erweiterung markiert).
|
||||
|
||||
## Ehrliche Hinweise / Risiken
|
||||
- **Terminal-Renderer**: komplette xterm-Fidelity ist kein Ziel; angestrebt ist ein robuster Renderer für typische Shell/`vim`/`htop`-Nutzung. Polarisierung (Unicode-Width, Truetype-Monospace-Messing) inkrementell.
|
||||
- **Hintergrund-Persistenz** echter Sessions braucht einen Foreground-Service (mit Notification) — im MVP wird die Session nur vor Config-Wechsel geschützt; der FG-Service ist klar als Folge-Task markiert.
|
||||
- **Kein echtes 1Password**: wird im UI ehrlich nicht suggeriert.
|
||||
|
||||
## Was du am Ende hast
|
||||
Ein lauffähiges Android-App-Projekt: Hosts/Keys verwalten (verschlüsselt gespeichert), über Passwort oder importierten Key verbinden, und ein **interaktives Compose-Terminal** für SSH-Sessions. Bauen mit `./gradlew assembleDebug`.
|
||||
|
||||
## Umsetzungshinweis
|
||||
Ich lege das komplette Projekt als neues Gradle-Projekt an (es ist aktuell ein leeres Verzeichnis) und implementiere alle Phasen. Bei sehr umfangreichen einzelnen Klassen (Terminal-Renderer, SshConnectionManager) halte ich sie fokunktional, aber schlank und klar kommentiert.

# Mobile SSH Manager
|
||||
|
||||
Android-App (Kotlin + Jetpack Compose) zum Verwalten von SSH-Verbindungen und zum
|
||||
interaktiven Arbeiten auf Servern über ein eingebautes Terminal.
|
||||
|
||||
## Stand / 1Password-Hinweis (bitte lesen)
|
||||
|
||||
Der ursprüngliche Wunsch war **1Password SSH Key Support**. Das ist auf Android
|
||||
aktuell **technisch nicht möglich**:
|
||||
|
||||
- Der 1Password SSH Agent ist **Desktop-only** (macOS, Windows, Linux).
|
||||
- Es gibt **keine Kotlin/Java-SDK** und keinen Android-Agent, nur Go/JS/Python-SDKs
|
||||
(Desktop/Server) und einen offenen [Feature-Request für Android][1p-fr].
|
||||
- Drittanbieter-Apps können 1Password-Schlüssel auf Android nicht einbinden.
|
||||
|
||||
[1p-fr]: https://www.1password.community/developers-69/feature-request-android-and-ssh-19991
|
||||
|
||||
**Stattdessen** unterstützt diese App den realistischen Workflow:
|
||||
Private Keys werden als Datei importiert (Storage Access Framework) und
|
||||
**AES-GCM-verschlüsselt via Android Keystore** gespeichert. Der praktische Weg mit
|
||||
1Password ist also: Key am Desktop aus 1Password exportieren → aufs Handy übertragen →
|
||||
in der App importieren. Kein 1Password-Bezug im UI, weil er ehrlicherweise nicht
|
||||
eingehalten werden könnte.
|
||||
|
||||
## Funktionen
|
||||
|
||||
- **Hosts** anlegen/bearbeiten/löschen (Name, Host, Port, User, Auth-Art)
|
||||
- **Authentifizierung** per Passwort oder per importiertem Private Key
|
||||
- **Keys importieren** (OpenSSH-/PEM-/PKCS8-/Ed25519-Formate via sshj + Bouncy Castle)
|
||||
- **Verbindung testen** direkt aus dem Host-Editor
|
||||
- **Interaktives Terminal**: Compose-Canvas-Renderer auf der Termux-`terminal-emulator`
|
||||
Engine (VT100/xterm, ANSI-Farben, Bold/Italic/Underline, Cursor, Alt-Buffer)
|
||||
- Tastatur-Erweiterungsleiste (ESC, Tab, Backspace, Pfeile)
|
||||
- Dunkles, terminal-orientiertes Theme
|
||||
|
||||
## Sicherheit
|
||||
|
||||
- Sensitive DB-Felder (Passwörter, private Keys) werden mit einem AES-GCM-Schlüssel aus
|
||||
dem **Android Keystore** ver- und entschlüsselt.
|
||||
- Klartext steht nur transient im Arbeitsspeicher (während Editieren/Verbinden).
|
||||
- Host-Verifikation ist aktuell **promiscuous** (MVP) — Known-Hosts-Speicher ist ein
|
||||
todo.
|
||||
|
||||
## Architektur
|
||||
|
||||
```
|
||||
core/crypto KeystoreCrypto (AES-GCM, Android Keystore)
|
||||
data Room (Host, SshKey, Group) + DAOs + Repositories + DI
|
||||
domain/model AuthType
|
||||
ssh SshConnectionManager (sshj), SshKeyParser, SshSupport (Bouncy Castle)
|
||||
terminal SshTerminalBridge (sshj <-> TerminalEmulator), TerminalTextStyle, KeyEncoder
|
||||
terminal/ui TerminalCanvas (Compose-Renderer), TerminalViewModel, TerminalScreen
|
||||
com.termux.terminal.TerminalBufferAccess Adapter auf package-private Buffer-Felder
|
||||
ui theme, nav, hostlist, hosteditor, keylist, keyimport, components
|
||||
```
|
||||
|
||||
### Terminal-Pipeline
|
||||
|
||||
```
|
||||
SSH-Server ──► sshj Shell.getInputStream()
|
||||
│ (Reader-Thread)
|
||||
▼
|
||||
TerminalEmulator.append(bytes) ← aktualisiert TerminalBuffer
|
||||
│
|
||||
▼ (Revision-Signal)
|
||||
TerminalCanvas (Compose) liest über TerminalBufferAccess
|
||||
│
|
||||
Tastatur ──► KeyEncoder ──► SshTerminalBridge.send() ──► sshj Shell.getOutputStream()
|
||||
```
|
||||
|
||||
Die Termux-Engine wird **direkt** (ohne `TerminalSession`, das lokale Prozesse startet)
|
||||
genutzt. Da `TerminalBuffer.mLines`/`TerminalRow.mText` package-private sind, greift
|
||||
`TerminalBufferAccess` als Klasse im `com.termux.terminal`-Package darauf zu.
|
||||
|
||||
## Stack
|
||||
|
||||
| Teil | Technologie |
|
||||
|------|-------------|
|
||||
| Sprache | Kotlin 2.0.21 (K2) |
|
||||
| UI | Jetpack Compose (BOM 2024.10), Material 3 |
|
||||
| DI | Hilt |
|
||||
| DB | Room 2.6 |
|
||||
| SSH | sshj 0.39 |
|
||||
| Krypto | Bouncy Castle 1.78 (Key-Parsing) + Android Keystore (Feldverschlüsselung) |
|
||||
| Terminal-Engine | Termux `terminal-emulator` 0.118.3 (via JitPack) |
|
||||
| Build | AGP 8.7.3, Gradle 8.11.1, JDK 17 target / JDK 21 zum Bauen |
|
||||
| SDK | compileSdk 34, minSdk 26 |
|
||||
|
||||
## Bauen
|
||||
|
||||
Voraussetzung: Android SDK mit `platforms;android-34` und `build-tools` sowie JDK 17/21.
|
||||
|
||||
```bash
|
||||
# Mit dem Gradle-Wrapper (JDK 21 empfohlen):
|
||||
JAVA_HOME=/pfad/zum/jdk-21 ./gradlew assembleDebug
|
||||
|
||||
# APK liegt dann hier:
|
||||
app/build/outputs/apk/debug/app-debug.apk
|
||||
```
|
||||
|
||||
Installieren auf einem verbundenen Gerät/Emulator:
|
||||
|
||||
```bash
|
||||
./gradlew installDebug
|
||||
# oder
|
||||
adb install app/build/outputs/apk/debug/app-debug.apk
|
||||
```
|
||||
|
||||
## Bekannte Einschränkungen / Todos
|
||||
|
||||
- **Passphrase-geschützte Keys**: Beim Import wird die Passphrase geprüft, für das Login
|
||||
müssen Keys aktuell unverschlüsselt gespeichert werden (MVP).
|
||||
- **Known-Hosts**: Host-Keys werden noch nicht verifiziert.
|
||||
- **Hintergrund-Persistenz**: Sessions überleben Konfigurationswechsel (die Activity fängt
|
||||
`configChanges` ab), aber für echtes Background-Keeping ist ein Foreground-Service
|
||||
nötig (Folgearchitektur).
|
||||
- **Terminal-Fidelity**: Ziel ist robuste Shell/`vim`/`htop`-Nutzung; exotische Features
|
||||
(Sixel, Maus-Reporting, Unicode-Width-Polierung) sind nicht Teil des MVP.
|
||||
- **Echtes 1Password**: erst möglich, wenn 1Password Android-Support anbietet.

# Gradle start up script for POSIX generated by Gradle.
|
||||
#
|
||||
# Important for running:
|
||||
#
|
||||
# (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
|
||||
# noncompliant, but you have some other compliant shell such as ksh or
|
||||
# bash, then to run this script, type that shell name before the whole
|
||||
# command line, like:
|
||||
#
|
||||
# ksh Gradle
|
||||
#
|
||||
# Busybox and similar reduced shells will NOT work, because this script
|
||||
# requires all of these POSIX shell features:
|
||||
# * functions;
|
||||
# * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
|
||||
# «${var#prefix}», «${var%suffix}», and «$( cmd )»;
|
||||
# * compound commands having a testable exit status, especially «case»;
|
||||
# * various built-in commands including «command», «set», and «ulimit».
|
||||
#
|
||||
# Important for patching:
|
||||
#
|
||||
# (2) This script targets any POSIX shell, so it avoids extensions provided
|
||||
# by Bash, Ksh, etc; in particular arrays are avoided.
|
||||
#
|
||||
# The "traditional" practice of packing multiple parameters into a
|
||||
# space-separated string is a well documented source of bugs and security
|
||||
# problems, so this is (mostly) avoided, by progressively accumulating
|
||||
# options in "$@", and eventually passing that to Java.
|
||||
#
|
||||
# Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
|
||||
# and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
|
||||
# see the in-line comments for details.
|
||||
#
|
||||
# There are tweaks for specific operating systems such as AIX, CygWin,
|
||||
# Darwin, MinGW, and NonStop.
|
||||
#
|
||||
# (3) This script is generated from the Groovy template
|
||||
# https://github.com/gradle/gradle/blob/HEAD/platforms/jvm/plugins-application/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
