ZPMLabs SSH Manager

Simple, OS-aware SSH configuration manager for PHP.

This package does not act as an SSH client.
Its purpose is to:

keep a structured list of SSH entries (users + keys + permissions) via a repository
scan the current OS for SSH users and keys
generate SSH key pairs for system users
optionally sync repository state with OS-level config (e.g. authorized_keys – per OS provider)

Installation

composer require zpmlabs/ssh-manager

Requires PHP 8.2+.

Basic Concepts

SshEntryEntity
Represents one SSH entry (user + key paths + groups + permissions).
SshRepositoryContract
Abstraction for storing entries (in memory, JSON, DB …).
SshManagerContract
High-level API for:
- listing entries
- create / update / delete
- scanning system users / keys
- generating key pairs for system users
SshManagerFactory
Creates an OS-specific SshManagerContract implementation (Linux / Windows / macOS / Android).

Quick Start

1. Create a Repository

For testing and simple usage there is an in-memory implementation:

use ZPMLabs\SshManager\Repositories\InMemorySshRepository;

$repository = new InMemorySshRepository();

Later, you can replace this with your own implementation of ZPMLabs\SshManager\Contracts\SshRepositoryContract (e.g. DB / JSON file).

2. Create the Manager via Factory

use ZPMLabs\SshManager\Factories\SshManagerFactory;

// Detect OS automatically and create a manager for it:
$manager = SshManagerFactory::make($repository);

SshManagerFactory internally uses SystemDetectorService + OperatingSystem enum to choose the correct provider:

Linux → LinuxSshManagerProvider
Windows → WindowsSshManagerProvider
macOS → MacOsSshManagerProvider
Android → AndroidSshManagerProvider

Listing Entries

There are two ways to list entries:

From your repository (listEntries) – what your app stores.
From the actual OS (scanSystemUsers) – what the OS currently has.

1) List all stored entries (from repository)

use ZPMLabs\SshManager\Entities\SshEntryEntity;

/** @var \ZPMLabs\SshManager\Contracts\SshManagerContract $manager */

// All entries, regardless of owner:
$entries = $manager->listEntries();

foreach ($entries as $entry) {
    /** @var SshEntryEntity $entry */
    echo $entry->getId() . PHP_EOL;
    echo 'User: ' . $entry->getUsername() . PHP_EOL;
    echo 'Home: ' . $entry->getHomeDirectory() . PHP_EOL;
    echo 'Public key path: ' . $entry->getPublicKeyPath() . PHP_EOL;
    echo 'Groups: ' . implode(', ', $entry->getGroups()) . PHP_EOL;
    echo str_repeat('-', 40) . PHP_EOL;
}

2) List entries for a specific owner (app-level user)

$ownerId = 'user-123';

$entriesForOwner = $manager->listEntries($ownerId);

3) Scan system users / keys (OS-level, read-only)

$systemEntries = $manager->scanSystemUsers();

foreach ($systemEntries as $entry) {
    echo $entry->getUsername() . PHP_EOL;
    echo 'Home: ' . $entry->getHomeDirectory() . PHP_EOL;
    echo 'Public key path: ' . $entry->getPublicKeyPath() . PHP_EOL;
    echo 'Groups: ' . implode(', ', $entry->getGroups()) . PHP_EOL;
    echo str_repeat('=', 40) . PHP_EOL;
}

scanSystemUsers() does not modify your repository.
It just inspects the current OS state (for Linux provider it reads /etc/passwd and ~/.ssh).

Creating Entries

You can create entries manually and store them in the repository via the manager.

use ZPMLabs\SshManager\Entities\SshEntryEntity;

$entry = new SshEntryEntity(
    id: 'entry-1',
    username: 'deploy',
    name: 'Deploy key',
    homeDirectory: '/home/deploy',
    publicKeyPath: '/home/deploy/.ssh/id_ed25519.pub',
    privateKeyPath: '/home/deploy/.ssh/id_ed25519',
    publicKey: null,          // optional – can be filled with file contents
    comment: 'Deployment key',
    groups: ['deploy', 'www-data'],
    ownerId: 'user-123',
    permissions: [],          // app-level permissions (see SshPermissionEntity)
);

// This writes to repository and triggers OS sync (if provider implements it).
$created = $manager->createEntry($entry);

// $created is the same entity, potentially modified by repository implementation.

Updating Entries

To update an existing entry:

/** @var \ZPMLabs\SshManager\Entities\SshEntryEntity|null $existing */
$existing = $manager->findEntry('entry-1');

if ($existing !== null) {
    $updatedEntry = new SshEntryEntity(
        id: $existing->getId(),
        username: $existing->getUsername(),
        name: 'Updated deploy key',
        homeDirectory: $existing->getHomeDirectory(),
        publicKeyPath: $existing->getPublicKeyPath(),
        privateKeyPath: $existing->getPrivateKeyPath(),
        publicKey: $existing->getPublicKey(),
        comment: 'Updated comment',
        groups: $existing->getGroups(),
        ownerId: $existing->getOwnerId(),
        permissions: $existing->getPermissions(),
    );

    $saved = $manager->updateEntry($updatedEntry);
}

updateEntry():

persists the updated entity in the repository
calls sync() on the provider (if implemented), so OS config can be refreshed.

Deleting Entries

To delete by ID:

$manager->deleteEntry('entry-1');

This:

Removes the entry from the repository.
Calls sync() on the provider, so OS-level configuration can be adjusted.

Generating SSH Key Pair for a System User

On Linux, LinuxSshManagerProvider provides a real implementation using ssh-keygen. On other OS providers it is currently a TODO (they throw a RuntimeException).

// This will:
// 1) Resolve the system user's home dir.
// 2) Create ~/.ssh if it doesn't exist.
// 3) Run ssh-keygen and create files (e.g. id_ed25519 and id_ed25519.pub).
// 4) Create a SshEntryEntity for this key.
// 5) Store it in the repository.
// 6) Call sync() on the provider.
$newEntry = $manager->generateKeyPairForUser(
    systemUsername: 'deploy',
    label: 'deploy@my-server',  // comment in the key
    keyType: 'ed25519',         // or 'rsa'
    bits: null                  // for rsa you can pass e.g. 4096
);

echo $newEntry->getUsername() . PHP_EOL;
echo $newEntry->getPublicKeyPath() . PHP_EOL;
echo $newEntry->getPrivateKeyPath() . PHP_EOL;

Finding a Single Entry

$entry = $manager->findEntry('entry-1');

if ($entry !== null) {
    echo $entry->getUsername() . PHP_EOL;
}

Extending the Package

You can extend the package in several ways:

Implement your own SshRepositoryContract:
- JSON file repository
- Database-backed repository (e.g. Doctrine / Eloquent / custom)
Implement OS-specific sync logic in providers:
- generate authorized_keys files
- update custom SSH config templates per entry
Add additional providers for specific environments or containers.

Laravel Integration

This package works seamlessly with Laravel. Here's how to integrate it:

Installation

composer require zpmlabs/ssh-manager

Service Provider Registration

Create a service provider to bind the SSH manager in Laravel's service container:

<?php

namespace App\Providers;

use Illuminate\Support\ServiceProvider;
use ZPMLabs\SshManager\Contracts\SshManagerContract;
use ZPMLabs\SshManager\Contracts\SshRepositoryContract;
use ZPMLabs\SshManager\Factories\SshManagerFactory;
use ZPMLabs\SshManager\Repositories\InMemorySshRepository;

class SshManagerServiceProvider extends ServiceProvider
{
    public function register(): void
    {
        // Bind repository (you can swap this with a database-backed implementation)
        $this->app->singleton(SshRepositoryContract::class, function ($app) {
            return new InMemorySshRepository();
            // Or use your own: return new DatabaseSshRepository();
        });

        // Bind SSH manager
        $this->app->singleton(SshManagerContract::class, function ($app) {
            $repository = $app->make(SshRepositoryContract::class);
            return SshManagerFactory::make($repository);
        });
    }
}

Register it in config/app.php:

'providers' => [
    // ...
    App\Providers\SshManagerServiceProvider::class,
],

Using Laravel Collections

The package returns arrays, but you can easily wrap them in Laravel Collections for better functionality:

use Illuminate\Support\Collection;
use ZPMLabs\SshManager\Contracts\SshManagerContract;

class SshEntryController extends Controller
{
    public function __construct(
        private SshManagerContract $sshManager
    ) {}

    public function index()
    {
        // Get entries as Laravel Collection
        $entries = collect($this->sshManager->listEntries());

        // Use Collection methods
        $groupedByOwner = $entries->groupBy(function ($entry) {
            return $entry->getOwnerId();
        });
        
        $withPublicKeys = $entries->filter(function ($entry) {
            return $entry->getPublicKey() !== null;
        });

        $usernames = $entries->map(function ($entry) {
            return $entry->getUsername();
        })->unique();

        return view('ssh-entries.index', [
            'entries' => $entries,
            'count' => $entries->count(),
        ]);
    }

    public function show(string $id)
    {
        $entry = $this->sshManager->findEntry($id);

        if (!$entry) {
            abort(404);
        }

        return view('ssh-entries.show', compact('entry'));
    }
}

Creating Entries in Laravel

use ZPMLabs\SshManager\Contracts\SshManagerContract;
use ZPMLabs\SshManager\Entities\SshEntryEntity;

class SshEntryController extends Controller
{
    public function store(Request $request, SshManagerContract $sshManager)
    {
        $validated = $request->validate([
            'username' => 'required|string',
            'name' => 'nullable|string',
            'comment' => 'nullable|string',
        ]);

        $entry = new SshEntryEntity(
            id: '',
            username: $validated['username'],
            name: $validated['name'] ?? null,
            homeDirectory: null,
            publicKeyPath: null,
            privateKeyPath: null,
            publicKey: null,
            comment: $validated['comment'] ?? null,
            groups: [],
            ownerId: auth()->id(), // Link to authenticated user
            permissions: [],
        );

        // This will generate SSH keys on the system automatically
        $created = $sshManager->createEntry($entry);

        return redirect()
            ->route('ssh-entries.show', $created->getId())
            ->with('success', 'SSH entry created successfully!');
    }
}

Using in Artisan Commands

<?php

namespace App\Console\Commands;

use Illuminate\Console\Command;
use Illuminate\Support\Collection;
use ZPMLabs\SshManager\Contracts\SshManagerContract;

class ListSshEntries extends Command
{
    protected $signature = 'ssh:list {--owner= : Filter by owner ID}';
    protected $description = 'List all SSH entries';

    public function handle(SshManagerContract $sshManager): int
    {
        $ownerId = $this->option('owner');
        $entries = collect($sshManager->listEntries($ownerId));

        if ($entries->isEmpty()) {
            $this->info('No SSH entries found.');
            return self::SUCCESS;
        }

        $this->table(
            ['ID', 'Username', 'Name', 'Home Directory', 'Public Key Path'],
            $entries->map(function ($entry) {
                return [
                    $entry->getId(),
                    $entry->getUsername(),
                    $entry->getName() ?? 'N/A',
                    $entry->getHomeDirectory() ?? 'N/A',
                    $entry->getPublicKeyPath() ?? 'N/A',
                ];
            })->toArray()
        );

        $this->info("Total: {$entries->count()} entries");

        return self::SUCCESS;
    }
}

Scanning System Users

use Illuminate\Support\Collection;
use ZPMLabs\SshManager\Contracts\SshManagerContract;

class SshEntryController extends Controller
{
    public function scanSystem(SshManagerContract $sshManager)
    {
        // Scan actual system users (OS-level, read-only)
        $systemEntries = collect($sshManager->scanSystemUsers());

        // Compare with repository entries
        $repositoryEntries = collect($sshManager->listEntries());
        
        $newEntries = $systemEntries->filter(function ($systemEntry) use ($repositoryEntries) {
            return !$repositoryEntries->contains(function ($repoEntry) use ($systemEntry) {
                return $repoEntry->getUsername() === $systemEntry->getUsername();
            });
        });

        return view('ssh-entries.scan', [
            'systemEntries' => $systemEntries,
            'repositoryEntries' => $repositoryEntries,
            'newEntries' => $newEntries,
        ]);
    }
}

Generating Keys for Users

use ZPMLabs\SshManager\Contracts\SshManagerContract;

class GenerateSshKeyCommand extends Command
{
    protected $signature = 'ssh:generate {username} {--label=}';
    protected $description = 'Generate SSH key pair for a system user';

    public function handle(SshManagerContract $sshManager): int
    {
        $username = $this->argument('username');
        $label = $this->option('label') ?: "{$username}@{$this->laravel->environment()}";

        try {
            $entry = $sshManager->generateKeyPairForUser(
                systemUsername: $username,
                label: $label,
                keyType: 'ed25519',
                bits: null
            );

            $this->info("SSH key pair generated successfully!");
            $this->line("Public key: {$entry->getPublicKeyPath()}");
            $this->line("Private key: {$entry->getPrivateKeyPath()}");
            
            if ($entry->getPublicKey()) {
                $this->line("Public key content:");
                $this->line($entry->getPublicKey());
            }

            return self::SUCCESS;
        } catch (\Exception $e) {
            $this->error("Failed to generate key: {$e->getMessage()}");
            return self::FAILURE;
        }
    }
}

Database-Backed Repository (Optional)

For production use, you might want to store entries in a database. Here's a basic example:

<?php

namespace App\Repositories;

use Illuminate\Support\Facades\DB;
use ZPMLabs\SshManager\Contracts\SshRepositoryContract;
use ZPMLabs\SshManager\Entities\SshEntryEntity;
use ZPMLabs\SshManager\Entities\SshPermissionEntity;

class DatabaseSshRepository implements SshRepositoryContract
{
    public function create(SshEntryEntity $entry): SshEntryEntity
    {
        $id = DB::table('ssh_entries')->insertGetId([
            'username' => $entry->getUsername(),
            'name' => $entry->getName(),
            'home_directory' => $entry->getHomeDirectory(),
            'public_key_path' => $entry->getPublicKeyPath(),
            'private_key_path' => $entry->getPrivateKeyPath(),
            'public_key' => $entry->getPublicKey(),
            'comment' => $entry->getComment(),
            'groups' => json_encode($entry->getGroups()),
            'owner_id' => $entry->getOwnerId(),
            'created_at' => now(),
            'updated_at' => now(),
        ]);

        return $this->find((string) $id) ?? $entry;
    }

    public function update(SshEntryEntity $entry): SshEntryEntity
    {
        DB::table('ssh_entries')
            ->where('id', $entry->getId())
            ->update([
                'username' => $entry->getUsername(),
                'name' => $entry->getName(),
                // ... update other fields
                'updated_at' => now(),
            ]);

        return $this->find($entry->getId()) ?? $entry;
    }

    public function delete(string $id): void
    {
        DB::table('ssh_entries')->where('id', $id)->delete();
    }

    public function find(string $id): ?SshEntryEntity
    {
        $row = DB::table('ssh_entries')->where('id', $id)->first();
        
        if (!$row) {
            return null;
        }

        return $this->mapRowToEntity($row);
    }

    public function all(?string $ownerId = null): array
    {
        $query = DB::table('ssh_entries');
        
        if ($ownerId) {
            $query->where('owner_id', $ownerId);
        }

        return $query->get()->map(function ($row) {
            return $this->mapRowToEntity($row);
        })->toArray();
    }

    protected function mapRowToEntity($row): SshEntryEntity
    {
        return new SshEntryEntity(
            id: (string) $row->id,
            username: $row->username,
            name: $row->name,
            homeDirectory: $row->home_directory,
            publicKeyPath: $row->public_key_path,
            privateKeyPath: $row->private_key_path,
            publicKey: $row->public_key,
            comment: $row->comment,
            groups: json_decode($row->groups ?? '[]', true),
            ownerId: $row->owner_id,
            permissions: [], // Load from separate table if needed
        );
    }
}

Then update your service provider:

$this->app->singleton(SshRepositoryContract::class, function ($app) {
    return new \App\Repositories\DatabaseSshRepository();
});

Helper Methods with Collections

You can create helper methods that return Collections for easier use:

<?php

namespace App\Services;

use Illuminate\Support\Collection;
use ZPMLabs\SshManager\Contracts\SshManagerContract;
use ZPMLabs\SshManager\Entities\SshEntryEntity;

class SshManagerService
{
    public function __construct(
        private SshManagerContract $manager
    ) {}

    public function entries(?string $ownerId = null): Collection
    {
        return collect($this->manager->listEntries($ownerId));
    }

    public function systemEntries(): Collection
    {
        return collect($this->manager->scanSystemUsers());
    }

    public function findByUsername(string $username): ?SshEntryEntity
    {
        return $this->entries()
            ->first(function ($entry) use ($username) {
                return $entry->getUsername() === $username;
            });
    }

    public function entriesForUser(int $userId): Collection
    {
        return $this->entries((string) $userId);
    }
}

Notes

All providers (Linux, Windows, macOS, Android) now have full CRUD implementations with SSH key generation.
When creating entries, SSH keys are automatically generated on the system.
All code and comments are kept framework-agnostic. You can easily build Laravel / Symfony integration on top of this package.
The package works great with Laravel Collections for filtering, mapping, and transforming SSH entry data.
