Key Features That Set Multron File Guardian Apart

• One-Click Encryption: Lock any file instantly without complex steps.
• Multiple Military-Grade Algorithms: Choose from AES, Serpent, Twofish, ThreeFish, Camellia, ChaCha20, SM4, HC, and hybrid RSA modes.
• Hybrid RSA Encryption: Perfect for secure file sharing; encapsulates symmetric keys using RSA (2048–16384 bits, default: 4096).
• Advanced Key Derivation: Uses Argon2id with customizable memory (256/512/1024 MB), parallelism, and password iteration count (default: 4).
• Per-File Randomization: Unique IV, nonce, and salt for every encrypted file to prevent pattern analysis.
• Advanced Encrypt-then-MAC Authentication: Ensures integrity and prevents tampering.
• File Compression Before Encryption: Reduce size while boosting security.
• Secure Deletion (Shredder) Option: Overwrite original files up to 99 times (default: 3 passes) to prevent recovery.
• Folder Encryption Support: Hold CTRL while browsing to select any folder; add Shift to include subfolders recursively.
• Note Protection via Multron NoteGuard: Save and encrypt text notes as .mng files.
• Screen Capture Protection: Blocks screenshots of the application window on Windows to prevent visual data leaks.
• Customizable Security Parameters: Adjust key size (where supported), Cipher mode (EtM or NO-Auth), and more.

Output & File Management

All encrypted files are saved with the .mfg extension, while protected notes use .mng. This clear distinction helps you manage your secure content effortlessly. The software preserves original filenames and directory structures during batch operations, making decryption intuitive and organized. System Requirements

• Operating System: Windows 11 (fully supported), Windows 10 (partially supported)
• Architecture: 64-bit (x64) CPU and OS required
• Runtime: .NET Core 10
