Parameters:

• count (number, required) - Number of certificates to generate

Returns:

[
  {
    id: number,                    // Certificate ID (1 to count)
    cn: string,                    // Common Name (e.g., 'api.local', 'db.dev')
    cert: string,                  // Certificate in PEM format
    key: string                    // Private key in PEM format
  },
  ...

Usage

const { generateCertificates } = require('self-certificate');

// Generate 10 random certificates
const certificates = generateCertificates(10);

// Each certificate has random validity (1 to 365 days)
// Each has a random CN from predefined services and domains
