+# FILECRYPTOR LITE – Simple Secure File Encryption Tool v1.0.0
+
+FILECRYPTOR LITE v1.0.0 is a lightweight desktop application designed for secure file encryption and decryption using password-based protection. It allows users to quickly encrypt multiple files into secure `.enc` format and decrypt them back using the correct password.
+
+Built with a modern Tkinter + ttkbootstrap interface, FILECRYPTOR LITE focuses on simplicity, speed, and offline security. It uses strong cryptographic standards including PBKDF2 key derivation and Fernet symmetric encryption to ensure data safety.
