PyCryptRSA: File Encryption and Decryption with RSA

Introduction

PyCryptRSA is a Python script that allows you to encrypt and decrypt files using the RSA (Rivest–Shamir–Adleman) encryption algorithm. RSA is widely used for securing data transmission and storage, and this tool provides an easy way to apply it to your files.

Features

• Encrypt files with a public key.
• Decrypt files with the corresponding private key.
• Supports various key sizes for customization.

Installation

1. Clone the repository to your local machine:

   git clone https://github.com/devthedud3/PyCryptRSA.git

2. Change into the project directory:

   cd PyCryptRSA

Usage

1. Generate RSA Keys

PyCryptRSA will generate RSA key pairs (public and private keys) for you. Ensure that the file(s) you want to encrypt/decrypt are in the same directory as this file.

The keys will be created in this same folder labeled encryption-keys/your-file-name

2. Encrypt or Decrypt a File

To encrypt a file, run the following command, and simply follow the prompt as directed.

python RSA.py

The system will then give you the option to encrypt or decrypt and then ask you to enter the filename, including EXT.

This will generate an encrypted file called encrypted_file.enc.

Security Considerations

• Keep your private key secure: Ensure that your private key (private.pem) is kept confidential and stored securely.
• Key size: Consider using larger key sizes for increased security, especially when dealing with sensitive data.
