encryptX - Encryption/Decryption Tool Manual

Overview

encryptX is a graphical tool for encrypting and decrypting files using AES-256 encryption with Python's cryptography library. It provides a user-friendly interface built with PyQt5.

Features

• Encrypt files securely using AES-256 encryption in CFB mode with PKCS7 padding.
• Decrypt previously encrypted files.
• Password validation to ensure security requirements are met.
• Progress bar to indicate encryption and decryption progress.
• Monokai-themed GUI for a modern and sleek appearance.

Requirements

• Python 3.x installed.
• Required Python packages (PyQt5, cryptography).

Installation

1. Ensure Python 3.x is installed on your system.
2. Install PyQt5 and cryptography packages:

   pip install PyQt5 cryptography

3. Download the encryptX script.

Usage

1. Starting the Application:

   • Run the script (encryptX.py) from the command line:

     python encryptX.py

   • The application window titled "encryptX - Encryption/Decryption Tool" will appear.

2. Encryption:

   • Click on the "Select file to Encrypt" button.
   • Choose the file you want to encrypt.
   • Enter a strong password in the "Enter your password" and "Confirm your password" fields.
   • Click on the "Encrypt" button.
   • If successful, a message will indicate the encryption process completion.
   • Progress of the encryption will be shown in the progress bar.

3. Decryption:

   • Click on the "Select file to Decrypt" button.
   • Choose the file you want to decrypt.
   • Enter the same password used during encryption in the "Enter your password" and "Confirm your password" fields.
   • Click on the "Decrypt" button.
   • If successful, a message will indicate the decryption process completion.
   • Progress of the decryption will be shown in the progress bar.

4. Password Requirements:

   • Password must be at least 8 characters long.
   • Must contain at least one digit, one special character, one uppercase letter, and one lowercase letter.

5. Error Handling:

   • If passwords do not match, a warning will prompt to re-enter.
   • If password does not meet requirements, a warning will specify the deficiencies.
   • Encryption or decryption failures will display an error message with details.

6. Styling:

   • The GUI is styled with a Monokai theme for an appealing visual experience.

Notes

• Ensure to remember your password as it is essential for decryption.
• Store encrypted files securely, along with their passwords.
• For advanced users, encryption parameters such as key derivation function (Scrypt) parameters (n, r, p) can be adjusted within the script for enhanced security.

Troubleshooting

• If encountering issues, ensure all required Python packages are installed.
• Check the terminal/console for error messages that may provide clues to the problem.
