v1.5.0

Secure File Cryptor - Professional Encryption Tool
🔐 Enhanced Security Features
Cryptographic Core:

AES-256-GCM Encryption - Military-grade encryption with authentication

PBKDF2 Key Derivation - 600,000 iterations for brute-force protection

Secure File Integrity - GCM tags (16 bytes per chunk) ensure tamper-proofing

Automatic Salt/Nonce - Unique cryptographically-secure values per operation

Note: The intentional 0.1-1% file size increase comes from GCM authentication tags - an essential security tradeoff that prevents file tampering.
✨ New UI/UX Improvements
User Control Features:

Optional Original File Deletion - Secure workflow integration

Password Visibility Toggle - Eye icon for password confirmation

Real-time Password Strength Meter - Color-coded strength indicator:

    🔴 Weak (<30%)

    🟡 Moderate (30-70%)

    🟢 Strong (>70%)

Streamlined Operations:

Automatic .encrypted/.decrypted Extensions - Consistent file handling

Output Folder Selection - Flexible decryption locations

Duplicate File Handling - Automatic naming conflicts resolution

🛡️ Security Architecture
File Processing:
text
Copy

[File Structure]
Original File -> [Salt (16B)][Nonce (12B)][Encrypted Chunks...]
Each chunk includes 16B GCM authentication tag

Key Security Advantages:

Tamper-Proof Design - GCM tags make modified files undecryptable

Secure Memory Handling - Keys never persisted to disk

Brute-Force Protection - 600K PBKDF2 iterations slow attacks
