Argon2

MedusaJS Argon2 Authentication Plugin

🔐 Enhanced password hashing for MedusaJS using the Argon2 algorithm - the most advanced and secure password hashing method.

🌟 Features

• Utilizes Argon2, the winner of the Password Hashing Competition
• Highly configurable password hashing
• Provides robust protection against various password cracking techniques
• Seamless integration with MedusaJS authentication

🛡️ Why Argon2?

Argon2 offers superior security compared to traditional hashing methods:

• Resistant to GPU and ASIC cracking attempts
• Configurable memory, time, and parallelism costs
• Adaptable to changing computational power
• Recommended by leading security experts

📦 Installation

Install the package using npm:

1
npm install @vymalo/medusa-argon2

Or using yarn:

1
yarn add @vymalo/medusa-argon2

🚀 Usage

Add the plugin to the Copy to clipboardmodules section of your MedusaJS configuration:

1234567891011121314151617181920
modules: [
  {
    resolve: '@medusajs/medusa/auth',
    options: {
      providers: [
        {
          resolve: '@vymalo/medusa-argon2',
          id: 'emailpass', // Yes, `emailpass`, as the goal is to override the default 
          options: {
            // Optional configuration parameters
            argon2: {
              timeCost: 3,
              memoryCost: 12288, // 12 MB
              parallelism: 1
            }
          },
        },
      ],
    },
  },

🔧 Configuration Options

The plugin supports full Argon2 configuration:

12345678910111213
interface Argon2Options {
  hashLength?: number;      // Length of the hash output (default: secure)
  timeCost?: number;        // Number of iterations (higher = more secure)
  memoryCost?: number;      // Memory usage in KB (higher = more secure)
  parallelism?: number;     // Number of parallel threads
  type?: 0 | 1 | 2;         // Argon2 variant (d, i, or id)
  version?: number;          // Argon2 version
  
  // Advanced options
  salt?: Buffer;             // Custom salt (usually auto-generated)
  associatedData?: Buffer;   // Additional context data
  secret?: Buffer;           // Secret key for additional security
}

Recommended Configuration

• Copy to clipboardtimeCost: Minimum 3, increase for more security
• Copy to clipboardmemoryCost: At least 12288 KB (12 MB)
• Copy to clipboardparallelism: 1-4 depending on your server
• Copy to clipboardtype: Recommended Copy to clipboard2 (Argon2id - hybrid mode)

🛡️ Security Recommendations

• Always use environment variables for sensitive configurations
• Periodically review and adjust hashing parameters
• Monitor computational resources and update costs as hardware evolves
