Prerequisites

Before you begin, ensure you have met the following requirements:

• You have installed Node.js.
• You have installed npm.

Using RSA Encryption/Decryption Module

To use the RSA module, follow these steps:

1. Clone this repository to your local machine.
2. Navigate to the project directory.
3. Install the required dependencies by running npm install.

Key Generation

Before you can encrypt or decrypt files, you need to generate a key pair. This can be done by running the following command:

npm run generate

This will generate a public and private key pair and save them in the project directory.

Encryption

To encrypt a message, run the following command:

npm run encrypt <data>

Replace <data> with the message you want to encrypt. This will print encrypted version of the message in the console.

Decryption

To decrypt a message, run the following command:

npm run decrypt <data>

Replace <data> with the message you want to decrypt. This will print a decrypted version of the message in the console.
