Replace all Chinese comments with English equivalents while preserving:
- Technical meaning and Linus-style direct tone
- Code structure and functionality
- User-facing text in UI components
Backend files cleaned:
- All utils/ TypeScript files
- Database routes and operations
- System architecture comments
- Field encryption documentation
All backend code now uses consistent English comments.
Problems Fixed:
• Hardcoded default JWT secret - global security disaster for open-source
• Over-complex "system master key" layer that solved no real threats
• Empty UserCrypto database methods breaking authentication
Linus-style Solution:
• Delete hardcoded keys completely - every instance gets unique random key
• Implement proper key loading priority: ENV → File → DB → Generate
• Complete UserCrypto implementation for KEK/DEK storage
• Automatic generation on first startup - zero configuration required
Security Improvements:
• Open-source friendly: Each instance has independent JWT secret
• Production ready: JWT_SECRET environment variable support
• Developer friendly: Auto-generation with file/database persistence
• Container friendly: Volume mount for .termix/jwt.key persistence
Architecture Simplification:
• Deleted complex system master key encryption layer
• Direct JWT secret storage - simple and effective
• File-first storage for performance, database fallback
• Comprehensive test suite validates all security properties
Testing:
• All 7 security tests pass including uniqueness verification
• No hardcoded secrets, proper environment variable priority
• File and database persistence working correctly
This eliminates the critical vulnerability where all Termix instances
would share the same JWT secret, making authentication meaningless.

This commit removes 500+ lines of fake "migration" code that admitted it couldn't
do what it claimed to do. Following Linus principles: if code can't deliver on
its promise, delete it rather than pretend.
Changes:
- DELETE: security-migration.ts (448 lines of fake migration logic)
- DELETE: SECURITY_REFACTOR_PLAN.md (outdated documentation)
- DELETE: /encryption/migrate API endpoint (non-functional)
- REPLACE: Complex "migration" with simple 3-line legacy user setup
- CLEAN: Remove all migration imports and references
The new approach is honest: legacy users get encryption setup on first login.
No fake progress bars, no false promises, no broken complexity.
Good code doesn't pretend to do things it can't do.
Major improvements:
- Replaced 226 Chinese comments with clear English equivalents across 16 files
- Backend security files: Complete English documentation for KEK-DEK architecture
- Frontend drag-drop hooks: Full English comments for file operations
- Database routes: English comments for all encryption operations
- Removed V1/V2 version identifiers, unified to single secure architecture
Files affected:
- Backend (11 files): Security session, user/system key managers, encryption operations
- Frontend (5 files): Drag-drop functionality, API communication, type definitions
- Deleted obsolete V1 security files: encryption-key-manager, database-migration
Benefits:
- International developer collaboration enabled
- Professional coding standards maintained
- Technical accuracy preserved for all cryptographic terms
- Zero functional impact, TypeScript compilation and tests pass
🎯 Linus-style simplification: Code now speaks one language - engineering excellence.

Removes all remaining hardware fingerprint validation logic to fix system
startup errors and improve cross-hardware compatibility.
Key changes:
- Remove hardware compatibility checks from database-file-encryption.ts
- Remove backup restore hardware validation from database.ts
- Remove database initialization hardware checks from db/index.ts
- Delete hardware-fingerprint.ts module entirely
- Update migration files to use fixed identifiers
Fixes "wmic is not recognized" and "Hardware fingerprint mismatch" errors
that were preventing system startup and database operations.
Problem Analysis:
- Fixed salt disaster: All same-type fields used identical encryption keys
- Exposed user password KEK protection as completely fake security theater
- System generated random password while claiming user password protection
- 500+ lines of complex migration logic for non-existent backward compatibility
Linus-Style Solutions Applied:
✅ "Delete code > Write code" - Removed 1167 lines of fake complexity
✅ "Complexity is evil" - Eliminated all special cases and migration paths
✅ "Practical solutions" - System auto-starts with secure random keys
✅ "Good taste" - Each field gets unique random salt, true data isolation
Core Changes:
• FIXED: Each encrypted field now gets unique random salt (no more shared keys)
• DELETED: MasterKeyProtection.ts - entire fake KEK protection system
• DELETED: encryption-test.ts - outdated test infrastructure
• SIMPLIFIED: User password = authentication only (honest design)
• SIMPLIFIED: Random master key = data protection (more secure than user passwords)
Security Improvements:
- Random keys have higher entropy than user passwords
- Simpler system = smaller attack surface
- Honest design = clear user expectations
- True field isolation = breaking one doesn't compromise others
Before: Break 1 password → Get all passwords of same type
After: Each field independently encrypted with unique keys
"Theory and practice sometimes clash. Theory loses. Every single time." - Linus
This removes theoretical security theater and implements practical protection.
VULNERABILITY ELIMINATED: Hardware fingerprint dependency created a false
sense of security while actually making attacks easier due to predictable
hardware information.
Core Changes:
- MasterKeyProtection: Replace hardware fingerprint with user password + random salt
- EncryptionKeyManager: Accept userPassword parameter for KEK derivation
- DatabaseEncryption: Pass userPassword through initialization chain
- Version bump: v1 (hardware) -> v2 (password-based) with migration detection
Security Improvements:
- TRUE RANDOMNESS: 256-bit random salt instead of predictable hardware info
- STRONGER KEK: PBKDF2 100,000 iterations with user password + salt
- CROSS-DEVICE SUPPORT: No hardware binding limitations
- FORWARD SECRECY: Different passwords generate completely different encryption
Technical Details:
- Salt generation: crypto.randomBytes(32) for true entropy
- KEK derivation: PBKDF2(userPassword, randomSalt, 100k, 32, sha256)
- Legacy detection: Throws error for v1 hardware-based keys
- Testing: New password-based KEK validation test
This eliminates the fundamental flaw where "security" was based on
easily obtainable system information rather than true cryptographic
randomness. Hardware fingerprints provided no actual security benefit
while creating deployment and migration problems.

SECURITY FIX: Replace dangerous JWT_SECRET environment variable with
encrypted database storage using hardware-bound KEK protection.
Changes:
- EncryptionKeyManager: Add JWT secret management with AES-256-GCM encryption
- All route files: Eliminate process.env.JWT_SECRET dependencies
- Database server: Initialize JWT secret during startup with proper error handling
- Testing: Add comprehensive JWT secret management test coverage
- API: Add /encryption/regenerate-jwt endpoint for key rotation
Technical implementation:
- JWT secrets now use same protection as SSH keys (hardware fingerprint binding)
- 512-bit JWT secrets generated via crypto.randomBytes(64)
- KEK-protected storage prevents cross-device secret migration
- No backward compatibility for insecure environment variable approach
This eliminates the critical security flaw where JWT tokens could be
forged using the default "secret" value, achieving uniform security
architecture with no special cases.

Following Linus principle: "功能不完整就不应该暴露给用户"
BEFORE: F2 key only printed console.log - useless UI control
AFTER: F2 properly triggers onStartEdit for file rename
This was a classic "half-baked" feature that frustrated users.
F2 is a standard Windows/Linux file manager shortcut.
Note: Could not locate "Straight button" mentioned in issue.
Searched all UI controls, sorting, layout functions - not found.
May have been removed or misnamed.
The core F2 rename issue is now resolved.
Following "good taste" principles to separate create intent from actual files:
DATA STRUCTURE REDESIGN:
- Add CreateIntent interface to separate intent from reality
- Replace mixed virtual/real file handling with pure separation
- Remove isCreatingNewFile state that caused confusion
ELIMINATE SPECIAL CASES:
- Cancel operation now has zero side effects (was creating default files)
- Remove complex conditional logic in handleCancelEdit
- Separate handleConfirmCreate from handleRenameConfirm responsibilities
SIMPLIFY USER FLOW:
- Create intent → Show UI → Confirm → Create file
- Cancel intent → Clean state → No side effects
- No more "NewFolder" + "UserName" duplicate creation
UI COMPONENTS:
- Add CreateIntentGridItem and CreateIntentListItem
- Render create intent separately from real files
- Focus/select input automatically with ESC/Enter handling
Resolves: Users reporting duplicate files on creation
Core fix: Eliminates the "special case" of cancel-creates-file
Result: Predictable, elegant file creation flow
Following Linus's "good taste" principles to eliminate race conditions:
- Add request ID tracking to prevent concurrent request conflicts
- Simplify loadDirectory function by removing complex reconnection logic
- Add reconnection lock to prevent concurrent SSH reconnections
- Implement 500ms refresh debouncing to prevent spam clicking
- Separate concerns: connection management vs file operations
Eliminates "special cases" that caused random state corruption.
The data structure now properly tracks request lifecycle.
Resolves file folder refresh showing stale content issue.
This commit eliminates the confusing requirePassword field that was causing
authentication issues where users couldn't disable password requirements.
Changes:
- Remove requirePassword field from database schema and migrations
- Simplify SSH authentication logic by removing special case branches
- Update frontend to remove requirePassword UI controls
- Clean up translation files to remove unused strings
- Support standard SSH empty password authentication
The new design follows the principle of "good taste" - password field itself
now expresses the requirement: null/empty = no password auth, value = use password.
Fixes the issue where setting requirePassword=false didn't work as expected.
