ISY-Crypto CLI Tool

Asimetric Encryptation recently added 🎉

ISY-Crypto is a powerful Command Line Interface (CLI) tool designed for encrypting and decrypting strings using the AES-256-CBC algorithm. It allows users to secure their data with a custom key, making it an essential utility for anyone looking to protect sensitive information.

Features

• Asymmetric Encryption: Encrypt and decrypt strings using a public and private RSA key pair.
• Custom Encryption Keys: Use any string as an encryption/decryption key.
• AES-256-CBC Encryption: Leverages the secure AES-256-CBC algorithm for encryption and decryption.
• Unique Outputs: Generates a unique output for the same input text by incorporating an initialization vector (IV).

Installation

Before installing ISY-Crypto, ensure you have Node.js installed on your system.

Option 1: Clone the Repository

Clone the repository to your local machine:

git clone https://github.com/yourusername/isy-crypto.git

Navigate to the project directory:

cd isy-crypto

Install the dependencies:

npm install

Option 2: Install via npm

Install ISY-Crypto globally using npm:

npm install -g isy-crypto

Usage

After installing ISY-Crypto globally via npm, you can use it directly from your terminal without navigating to a specific project directory.

Generating RSA Keys

To generate a public and private RSA key pair, use the isy-crypto keygen command. This will generate an RSA key pair and save it to the specified output directory or print it to the console.

The default name is id-rsa-[public|private].pem. In later versions, the name will be customizable.

isy-crypto keygen -p /path/to/output/directory

⚠️ If -p or --path is not passed, the keys will be printed to the console.

Encrypting Text

To encrypt a string, simply open your terminal and use the isy-crypto encrypt command followed by the text you wish to encrypt. Specify the encryption key with the -k or --key option.

For example:

isy-crypto encrypt "Hello, World!" -k "your_secret_key"
> Encrypted: 
45f5fc53dc3ef1f1af50f1205487e021:353a8541b838d8587dab4922b565545b

Encrypting Text with RSA Public Key

To encrypt a string using a public RSA key, use the isy-crypto encrypt command followed by the text you wish to encrypt and the option -a or --asimetric. Specify the public key with the -p or --path option.

node index.js encrypt "Hello World" -a -p /path/to/public/key.pem
> Encrypted: 
r3XsAzpi0T3dp1rPQannoXxFTt0x...FiKdH3ArEycMZCLegGTXO1fdJ2mklRIm1DIzdR7c=

Decrypting Text

To decrypt a string, use the isy-crypto decrypt command followed by the encrypted text. Specify the decryption key with the -k or --key option.

For example:

isy-crypto decrypt "45f5fc53dc3ef1f1af50f1205487e021:353a8541b838d8587dab4922b565545b" -k "your_secret_key"
> Decrypted: 
Hello, World!

Encrypting Text with RSA Private Key

To decrypt a string using a private RSA key, use the isy-crypto decrypt command followed by the text you wish to decrypt and the option -a or --asimetric. Specify the private key with the -p or --path option.

node index.js decrypt "r3XsAzpi0T3dp1rPQannoXxFTt0x...FiKdH3ArEycMZCLegGTXO1fdJ2mklRIm1DIzdR7c=" -a -p /path/to/private/key.pem
> Decrypted:
"Hello World"
