CLI tool to encrypt and decrypt strings using AES-256-CBC
npm install isy-cryptoISY-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.
- 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).
Before installing ISY-Crypto, ensure you have Node.js installed on your system.
Clone the repository to your local machine:
``bash`
git clone https://github.com/Cocodrilette/isy-crypto.git
Navigate to the project directory:
`bash`
cd isy-crypto
Install the dependencies:
`bash`
npm install
Install ISY-Crypto globally using npm:
`bash`
npm install -g isy-crypto
After installing ISY-Crypto globally via npm, you can use it directly from your terminal without navigating to a specific project directory.
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.
`bash`
isy-crypto keygen -p /path/to/output/directory
⚠️ If or --path is not passed, the keys will be printed to the console.
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:
`bash`
isy-crypto encrypt "Hello, World!" -k "your_secret_key"
> Encrypted:
45f5fc53dc3ef1f1af50f1205487e021:353a8541b838d8587dab4922b565545b
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.
`bash`
node index.js encrypt "Hello World" -a -p /path/to/public/key.pem
> Encrypted:
r3XsAzpi0T3dp1rPQannoXxFTt0x...FiKdH3ArEycMZCLegGTXO1fdJ2mklRIm1DIzdR7c=
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:
`bash`
isy-crypto decrypt "45f5fc53dc3ef1f1af50f1205487e021:353a8541b838d8587dab4922b565545b" -k "your_secret_key"
> Decrypted:
Hello, World!
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.
`bash``
node index.js decrypt "r3XsAzpi0T3dp1rPQannoXxFTt0x...FiKdH3ArEycMZCLegGTXO1fdJ2mklRIm1DIzdR7c=" -a -p /path/to/private/key.pem
> Decrypted:
"Hello World"
