From 92b0124cc57abdbcc37d48e589a0631a298861c9 Mon Sep 17 00:00:00 2001 From: Faded Date: Tue, 21 Oct 2025 01:38:22 +0500 Subject: [PATCH 1/7] Add recovery code security tests and implement password recovery flow - Introduced a new test suite for recovery code security in `test_recovery_security.py` to validate: - Code generation uniqueness - Code encryption and decryption - One-time use enforcement - Tamper detection - Brute force resistance - File deletion/corruption handling - Modified `MainWindowBase` to integrate recovery code functionality: - Added `verify_password_with_recovery` method for password verification with recovery options. - Updated password dialog to include a "Forgot Password?" link that initiates recovery. - Created `RecoveryCodeDialog` and `RecoveryCodesDisplayDialog` for user interactions during password recovery: - Users can enter recovery codes and set new passwords. - Display generated recovery codes with warnings about their usage. - Enhanced the UI with appropriate styles and messages to guide users through the recovery process. --- core/password_manager.py | 172 ++++++++++- core/recovery_manager.py | 359 +++++++++++++++++++++ tests/test_recovery_security.py | 389 +++++++++++++++++++++++ ui/base/main_window_base.py | 169 ++++++++-- ui/dialogs/password_dialog.py | 30 ++ ui/dialogs/recovery_dialog.py | 530 ++++++++++++++++++++++++++++++++ 6 files changed, 1623 insertions(+), 26 deletions(-) create mode 100644 core/recovery_manager.py create mode 100644 tests/test_recovery_security.py create mode 100644 ui/dialogs/recovery_dialog.py diff --git a/core/password_manager.py b/core/password_manager.py index a1bc660..5f7734e 100644 --- a/core/password_manager.py +++ b/core/password_manager.py @@ -1,11 +1,12 @@ """ Password Manager - Master Password Operations -Handles master password creation, verification, and changes +Handles master password creation, verification, changes, and recovery codes """ import os -from typing import Optional, Callable +from typing import Optional, Callable, List, Tuple from .crypto_manager import CryptoManager +from .recovery_manager import RecoveryCodeManager class PasswordManager: @@ -22,21 +23,29 @@ class PasswordManager: cached_password: In-memory cache of password (bytes) """ - def __init__(self, password_file_path: str, crypto_manager: Optional[CryptoManager] = None): + def __init__(self, password_file_path: str, crypto_manager: Optional[CryptoManager] = None, recovery_codes_file_path: Optional[str] = None): """ Initialize the PasswordManager.

Added functionality to protect critical files (recovery codes, encrypted passwords) from deletion/tampering when monitoring is active. - Integrated file protection logic into the main window, ensuring critical files are protected upon starting monitoring and unprotected on exit. - Enhanced the Linux file lock manager to exclude FadCrypt's own process from being terminated during file protection. - Created a test suite for recovery code persistence, ensuring recovery codes remain valid after password resets and are marked as consumed when used. --- core/file_protection.py | 509 +++++++++++++++++++++++ core/linux/file_lock_manager_linux.py | 11 +- tests/test_recovery_persistence.py | 576 ++++++++++++++++++++++++++ ui/base/main_window_base.py | 41 ++ 4 files changed, 1136 insertions(+), 1 deletion(-) create mode 100644 core/file_protection.py create mode 100644 tests/test_recovery_persistence.py diff --git a/core/file_protection.py b/core/file_protection.py new file mode 100644 index 0000000..76f728d --- /dev/null +++ b/core/file_protection.py @@ -0,0 +1,509 @@ +""" +File Protection Manager +Protects critical files (recovery codes, config) from deletion/modification when monitoring is active. + +Platform-specific implementations: +- Windows: SetFileAttributesW (HIDDEN + SYSTEM + READONLY) +- Linux: chattr +i (immutable flag) or restrictive permissions +""" + +import os +import sys +import stat +from typing import List, Tuple, Optional + +# Platform detection +IS_WINDOWS = sys.platform == 'win32' +IS_LINUX = sys.platform.startswith('linux') + +if IS_WINDOWS: + try: + import ctypes + from ctypes import windll, wintypes + WINDOWS_AVAILABLE = True + except ImportError: + WINDOWS_AVAILABLE = False + print("[FileProtection] ⚠️ Windows ctypes not available") +else: + WINDOWS_AVAILABLE = False + + +class FileProtectionManager: + """ + Manages file protection to prevent tampering with critical files during monitoring. + + Protection Methods: + -
