An application for encrypting files and folders

Description

This is an application for encrypting and decrypting files and folders using various encryption algorithms. The application provides a choice between AES, RSA and ChaCha20 algorithms. The "fast encryption/decryption" feature is also implemented, which allows you to quickly encrypt or decrypt a file/folder using the default algorithm.

Functionality

• Encryption and decryption: Encrypts and decrypts files and folders, ensuring data privacy.
• Choosing an encryption algorithm: Supports three encryption algorithms:
  • AES (Advanced Encryption Standard): Symmetric encryption algorithm, providing high speed and security.
  • RSA (Rivest–Shamir–Adleman): An asymmetric encryption algorithm that uses a pair of keys (public and private) for encryption and decryption.
  • ChaCha20: Symmetric stream cipher, known for its high speed and security, especially on platforms without AES hardware support.
• Fast encryption/decryption (context menu): Adds an option to the context menu of files and folders in your operating system that allows you to quickly encrypt or decrypt a file/folder using the default encryption algorithm.
• Default encryption algorithm: Allows the user to select the default encryption algorithm to be used for fast encryption/decryption. The algorithm can be selected in the menu of the console application.

Dependencies

• OpenSSL (for cryptographic operations).
