EncryptionTool

Overview

EncryptionTool is a very simple C# console application designed for file encryption and decryption using AES-256. This tool can be used for securing files by encrypting them and later decrypting them with the same key and initialization vector (IV).

Features

• Encrypt any file with AES-256 encryption.
• Decrypt files using the previously generated key and IV.
• Automatically generates and stores encryption keys and IVs.

Getting Started

Prerequisites

• .NET SDK installed on your machine.

Installation

1. Clone the repository to your local machine:

2. Navigate to the project directory:

   cd EncryptionTool

3. Build the project:

   dotnet build

Usage

1. Run the application:

   dotnet run

2. Follow the on-screen instructions to either encrypt or decrypt a file:
   • To encrypt a file, enter encrypt and provide the relative path to the file you want to encrypt.
   • To decrypt a file, enter decrypt and provide the relative paths to both the encrypted file and the key & IV file.

Example

• To encrypt a file named example.txt in the project root directory:

  Do you want to encrypt or decrypt a file? (Type 'encrypt' or 'decrypt')
  encrypt
  Enter the relative path of the file to encrypt (relative to project root):
  example.txt
  Key & IV file created at: <project_root>/encryption.keyiv
  File encrypted to: <project_root>/example.txt.enc
  

• To decrypt the previously encrypted file:

  Do you want to encrypt or decrypt a file? (Type 'encrypt' or 'decrypt')
  decrypt
  Enter the relative path of the file to decrypt (relative to project root):
  example.txt.enc
  Enter the relative path of the key & IV file (relative to project root):
  encryption.keyiv
  File decrypted to: <project_root>/example.txt.enc.dec
