refactor: improve key validation architecture - #54
Conversation
WalkthroughCommands now prompt for a raw public-key path which is resolved via new resolver/fallback helpers; FilesystemService adds tilde-expansion and first-existing lookup; SSHService API now requires explicit private-key paths and no longer performs internal key-path resolution; validation and traits updated to use the new filesystem-backed helpers and surface concrete errors.

27-37: Critical: Catch RuntimeException from expandPath to honor validation contract.The call to
$this->fs->expandPath($path)on line 32 can throwRuntimeExceptionwhen the HOME environment variable is not set. This violates the coding guidelines for validation methods, which state: "Validation methods for prompts/options must accept mixed and return ?string error or null (do not throw exceptions)."Apply this diff to catch and handle the exception:
// Allow empty paths (will trigger default key resolution) if (trim($path) === '') { return null; } - $expandedPath = $this->fs->expandPath($path); + try { + $expandedPath = $this->fs->expandPath($path); + } catch (\RuntimeException $e) { + return $e->getMessage(); + } // Check if file exists if (!$this->fs->exists($expandedPath)) {

133-143: Consider resilience to expandPath failures for fallback resolution.Currently, if
expandPaththrowsRuntimeException(e.g., HOME not set) while processing a tilde path, the entire method fails. This prevents trying subsequent non-tilde paths in the candidates array.For example, if a user provides an absolute path and the fallback list includes
~/.ssh/id_ed25519, the current implementation would throw when HOME is not set instead of using the user's absolute path.Consider catching and skipping paths that fail to expand:
public function getFirstExisting(array $paths): ?string { foreach ($paths as $path) { - $expandedPath = $this->expandPath($path); - if ($this->exists($expandedPath)) { - return $expandedPath; + try { + $expandedPath = $this->expandPath($path); + if ($this->exists($expandedPath)) { + return $expandedPath; + } + } catch (\RuntimeException) { + // Skip paths that cannot be expanded (e.g., ~ paths when HOME not set) + continue; } } return null; }

app/Services/FilesystemService.php (1)
112-124: LGTM: Clean tilde expansion with appropriate error handling.The implementation correctly handles empty paths and non-tilde paths, and throws a clear exception when HOME is not set for tilde paths.
app/Traits/KeyHelpersTrait.php (1)
32-85: LGTM: Clean key path resolution with sensible defaults.The refactoring successfully centralizes key path resolution with a clear priority order. The implementation correctly:
- Prioritizes user-provided paths over defaults
- Uses modern SSH key types (Ed25519) as the first fallback
- Delegates path expansion and existence checking to the filesystem service
- Returns null when no valid path is found, allowing callers to handle appropriately
app/Console/Key/KeyAddDigitalOceanCommand.php (2)
62-82: LGTM: Clear separation of validation and resolution.The refactored flow correctly:
- Validates user input without modifying it
- Resolves to an actual path with fallback defaults
- Provides clear feedback when resolution fails
- The prompt explicitly lists the default paths, improving user experience
The explicit null check on line 78 ensures users get a clear error when no valid key is found, rather than a cryptic failure downstream.
108-119: Good improvement: Using actual exception message.Line 115 now uses
$e->getMessage()instead of a generic error string, providing more actionable error information to users.app/Services/SSHService.php (3)
17-38: Excellent documentation update.The updated examples clearly demonstrate the new explicit path requirement and helpfully note that "commands resolve key paths before calling," making the architectural change clear to future maintainers.
42-60: LGTM: Cleaner separation of concerns.Removing the
EnvServicedependency and requiring explicitprivateKeyPathparameters simplifies the service's responsibilities. Path resolution is now correctly handled by callers (viaKeyHelpersTrait), making the service stateless and focused solely on SSH operations.
248-267: LGTM: Simplified private key loading.The
loadPrivateKeymethod is now focused purely on loading and validating a provided path, with clear error messages for each failure mode. The removal of internal path resolution and fallback logic aligns with the PR's architectural goals.

32-36: Consider narrowing exception handling.Catching
\Throwableis very broad and can mask unexpected errors likeOutOfMemoryErrororParseError. SinceFilesystemService::expandPath()throws\RuntimeException(per the code snippet), consider catching\Exceptioninstead.However, for user-facing validation that must not crash, the current approach is defensible.
Apply this diff if you prefer narrower exception handling:
try { $expandedPath = $this->fs->expandPath($path); - } catch (\Throwable $e) { + } catch (\Exception $e) { return $e->getMessage(); }

27-30: LGTM: Empty path handling enables flexible default resolution.Allowing empty paths to pass validation (returning null) is a sensible design that enables commands to implement their own default key resolution logic.
49-77: LGTM: Comprehensive SSH key type validation.The expanded list of valid SSH key prefixes covers modern key types including FIDO2/U2F security keys, and explicitly rejects obsolete DSA keys with a clear error message. This aligns with current SSH security best practices.
Note:
ssh-rsais included but being phased out in newer OpenSSH versions. However, it remains widely used, so its inclusion is appropriate for compatibility.

44-66: Consider extracting hardcoded fallback paths to constants.The fallback paths are currently hardcoded in each method. Extracting them to class constants would improve maintainability and make it easier to adjust the fallback order in the future.
Example refactor:
+ /** @var array<int, string> */ + private const PRIVATE_KEY_FALLBACKS = [ + '~/.ssh/id_ed25519', + '~/.ssh/id_rsa', + ]; + + /** @var array<int, string> */ + private const PUBLIC_KEY_FALLBACKS = [ + '~/.ssh/id_ed25519.pub', + '~/.ssh/id_rsa.pub', + ]; + protected function resolvePrivateKeyPath(?string $path): ?string { - return $this->resolveKeyWithFallback($path, [ - '~/.ssh/id_ed25519', - '~/.ssh/id_rsa', - ]); + return $this->resolveKeyWithFallback($path, self::PRIVATE_KEY_FALLBACKS); } protected function resolvePublicKeyPath(?string $path): ?string { - return $this->resolveKeyWithFallback($path, [ - '~/.ssh/id_ed25519.pub', - '~/.ssh/id_rsa.pub', - ]); + return $this->resolveKeyWithFallback($path, self::PUBLIC_KEY_FALLBACKS); }
83-84: Simplify redundant type check.The
is_string($path)check is redundant given the?stringtype hint. PHP's type system guarantees that if$pathis notnull, it's already astring.As per coding guidelines.
Apply this diff to simplify the check:
- if (is_string($path) && $path !== '') { + if ($path !== null && $path !== '') { $candidates[] = $path; }

35-41: Remove redundant token null/empty check or makeget(..., required: false).EnvService::get throws \InvalidArgumentException when required (default). The manual null/empty check won’t run. Prefer one path:
- Option A (simpler): rely on exception and drop the manual check.
- Option B: call get([...], false) and keep the explicit check.
Diff for Option A:
try { - $apiToken = $this->env->get(['DIGITALOCEAN_API_TOKEN', 'DO_API_TOKEN']); - - if ($apiToken === null || $apiToken === '') { - throw new \InvalidArgumentException('DigitalOcean API token not found in environment'); - } + $apiToken = $this->env->get(['DIGITALOCEAN_API_TOKEN', 'DO_API_TOKEN']);app/Traits/KeyHelpersTrait.php (3)
46-52: Consider adding ECDSA private-key fallback.Some setups still use ~/.ssh/id_ecdsa. Non-breaking addition:
protected function resolvePrivateKeyPath(?string $path): ?string { return $this->resolveKeyWithFallback($path, [ '~/.ssh/id_ed25519', '~/.ssh/id_rsa', + '~/.ssh/id_ecdsa', ]); }
62-68: Public key UX: try ".pub" first when a private key path is supplied.Improves ergonomics if users paste a private key path by habit.
protected function resolvePublicKeyPath(?string $path): ?string { - return $this->resolveKeyWithFallback($path, [ - '~/.ssh/id_ed25519.pub', - '~/.ssh/id_rsa.pub', - ]); + $fallback = ['~/.ssh/id_ed25519.pub', '~/.ssh/id_rsa.pub']; + + if (is_string($path) && $path !== '' && !str_ends_with($path, '.pub')) { + // Prefer "<path>.pub" if user provided a private key path + return $this->resolveKeyWithFallback(null, [$path . '.pub', $path, ...$fallback]); + } + + return $this->resolveKeyWithFallback($path, $fallback); }
81-92: Ensure returned path is a file, not a directory.FilesystemService::getFirstExisting considers directories. For key resolution we only want files. Two options:
- Short term: add a file-only helper and use it here (preferred).
- Alternative: reimplement the candidate scan locally checking
is_dir/is_file.If you want, I can draft a FilesystemService::getFirstExistingFile(array $paths): ?string and update callers.
app/Traits/KeyValidationTrait.php (2)
33-36: Improve diagnostics: show expanded path and preserve error cause.
- Consider reporting the expanded path for not-found errors (helps when
~expands unexpectedly).- Preserve underlying read errors to aid troubleshooting.
- if (!$this->fs->exists($expandedPath)) { - return "SSH key file not found: {$path}"; - } + if (!$this->fs->exists($expandedPath)) { + return "SSH key file not found: {$expandedPath}" . ($expandedPath !== $path ? " (from {$path})" : ""); + } @@ - } catch (\Throwable) { - return 'Could not read SSH key file'; + } catch (\Throwable $e) { + return 'Could not read SSH key file: ' . $e->getMessage(); }Also applies to: 38-42, 45-47
49-67: Validate the base64 blob, not just the key-type prefix.Extra guard to reject corrupted keys while keeping the validate*Input contract:
- $isValid = false; - foreach ($validPrefixes as $prefix) { - if (str_starts_with($publicKey, $prefix)) { - $isValid = true; - break; - } - } - - if (!$isValid) { + // Split into "<type> <base64> [comment...]" + $parts = preg_split('/\s+/', $publicKey, 3); + if (!$parts || count($parts) < 2) { + return 'Invalid SSH public key format'; + } + [$type, $b64] = $parts; + + if (!in_array($type, $validPrefixes, true)) { // Explicit error for obsolete DSA keys - if (str_starts_with($publicKey, 'ssh-dss')) { + if ($type === 'ssh-dss') { return 'DSA (ssh-dss) keys are obsolete and insecure'; } return 'Invalid SSH public key format'; } + + if (base64_decode($b64, true) === false) { + return 'Invalid SSH public key (corrupted base64 data)'; + }Also applies to: 68-84

If any heavy I/O validations are added later, mirror them in a throwing
validatePublicKeyPath()and keep this method light per guidelines.
