TAVDATA - Secure Data Manager

TavData is a secure password vault and local database manager built for people who value total privacy. With military-grade encryption, you can store passwords, notes, card numbers, and documents with zero cloud dependency — everything stays encrypted and local on your device. Protect your digital life with a 100% offline app that offers fast access, advanced encryption (AESNI-GCM, BLAKE2), and smart key management. Ideal for managing logins, banking data, personal notes, and confidential records — safely and efficiently. - MILITARY GRADE ENCRYPTION & Compliance (NIST FIPS 197, SP 800-38D, SP 800-90A) - AESNI-GCM 256-bit encryption (Galois Counter Mode). - BLAKE2 512-bit key derivation and deterministic 96-bit NONCE. FEATURES: SELECTIVE DECRYPTION Decrypt only the records you need when you enter your secret key; all other data remains fully protected against unauthorized access. SMART KEY MANAGEMENT Choose auto or manual key reset. Clear keys from memory at any time or set a smart timeout that pauses during data entry so you never feel rushed. NO CLOUD, NO INTERNET All encryption and data management happen entirely on your device—no internet required and no third-party services. INTUITIVE CROSS-PLATFORM INTERFACE Organize multiple databases with a tree-style structure and unlimited subcategories for personal, professional, emergency, or banking information. Export/import for offsite backups or use on other devices. HIGH PERFORMANCE Built on the latest .NET Core with asynchronous SQLite and hardware acceleration for minimal latency and maximum throughput. Your security is our top priority. Try TavData today—risk-free for 14 days! SPECS: ✓ AES-GCM and AESNI-GCM algorithm implementations (256/256), with hardware acceleration support (when available) for maximum efficiency. ✓ Optimized performance, delivering the lowest latency and highest data throughput among all AES-256 implementations. ✓ Authentication and integrity ensured through KECCAK 256-bit (SHA3) and 96-bit non-repeating NONCE, deterministically generated by the BLAKE2 algorithm to prevent replay attacks. ✓ BLAKE2 hash function operating in 512-bit mode, providing high security and processing efficiency. ✓ Secret key derivation and entropy generation enhanced by BLAKE2, reinforcing protection against cryptographic attacks. ✓ Utilization of a validated cryptographically secure random number generator based on the RandomNumberGenerator from .NET Core, ensuring a high level of unpredictability. ✓ Secure key management, with automatic sanitization of sensitive data through direct memory addressing, along with forced removal via Garbage Collection, triggered automatically upon the key entry, upon the program termination or based on user-defined criteria. ✓ Asynchronous SQLite database engine, delivering enhanced performance and efficiency when handling large data volumes.
