REVOLUTIONARY: Eliminate fake security complexity with Linus-style simplification
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more shared keys) • DELETED: MasterKeyProtection.ts - entire fake KEK protection system • DELETED: encryption-test.ts - outdated test infrastructure • SIMPLIFIED: User password = authentication only (honest design) • SIMPLIFIED: Random master key = data protection (more secure than user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.
