FileCrypto CLI

A command-line utility (CLI) developed in Free Pascal, focused on demonstrating pure data structures (Records and dynamic Linked Lists using pointers) and byte-level encryption operations (XOR).

Features

• In-Memory Metadata Management: Dynamic storage of file information (Name, Size, and Extension) using pointers and heap allocation.
• Dynamic Linked List: Manual implementation of node (TFileNode) insertion, listing, and deallocation to prevent memory leaks.
• Symmetric XOR Encryption: Byte-by-byte binary reading and writing applying a reversible XOR mask; suitable for text or binary files.
