Certificate Generator

The generateCert module provides a function for generating RSA key pairs and saving them as certificate files. These certificates are essential for signing authentication tokens, ensuring secure communication between the server and clients.

Features

• RSA Key Pair Generation: Generates RSA key pairs with a modulus length of 4096 bits for enhanced security.
• Certificate File Creation: Saves the generated private and public keys as certificate files in the specified directory.
• Directory Verification: Checks if the target directory exists and creates it if not.
• Error Handling: Provides informative console messages and returns an object indicating the success of the certificate generation process.

Usage

const { generateCert } = require('apiutils.js');
 
try {
  const result = generateCertificate();
  console.log(result.msg);
} catch (error) {
  console.error('Error generating certificate:', error);
}

Return Value

• If the certificate generation is successful, returns an object with the message "Certificate generated successfully at [certPath]" and ok: true.
• If the certificate already exists, returns a message indicating that the certificate already exists at the specified path.
• If any error occurs during the certificate generation process, throws an error with a descriptive message.

Certificate Usage

The generated RSA key pair can be used for signing authentication tokens, ensuring secure and tamper-proof communication between the server and clients. The private key is used to sign the tokens, while the public key is used to verify their authenticity.

Certificate Files

The generated certificate consists of two files:

• cert.pem: Contains the private key.
• cert.pem.pub: Contains the public key.
