JSPM

Cryptographic security rules enforcing best practices and modern standards (Node.js crypto).

Description

This plugin enforces cryptographic best practices and modern security standards specifically for Node.js environments. It assists developers in avoiding weak algorithms and insecure implementations by flagging potential risks directly in the code. By integrating these checks, you can ensure that your application's data protection measures are robust and compliant with industry standards.

Philosophy

Interlace fosters strength through integration. Instead of stacking isolated rules, we interlace security directly into your workflow to create a resilient fabric of code. We believe tools should guide rather than gatekeep, providing educational feedback that strengthens the developer with every interaction.

Library	npm	Downloads	Detection
crypto (Node.js)		-	Weak Algo, Key Length, Randomness
crypto-js			Legacy patterns, Weak PRNG

Examples

❌ Bad

// CVE-2023-46809: Marvin Attack
crypto.privateDecrypt({ key, padding: crypto.constants.RSA_PKCS1_PADDING }, buffer);

// CWE-338: Weak random
const token = Math.random().toString(36);

// CWE-327: ECB mode leaks patterns
crypto.createCipheriv('aes-256-ecb', key, iv);

// CWE-208: Timing attack
if (userToken === storedToken) { ... }

✅ Good

// Use OAEP padding
crypto.privateDecrypt({ key, padding: crypto.constants.RSA_PKCS1_OAEP_PADDING }, buffer);

// Secure random
const token = crypto.randomBytes(32).toString('hex');

// GCM provides authentication
crypto.createCipheriv('aes-256-gcm', key, iv);

// Constant-time comparison
if (crypto.timingSafeEqual(Buffer.from(userToken), Buffer.from(storedToken))) { ... }

Peer Dependencies (Optional)

{
  "crypto-hash": ">=3.0.0",
  "crypto-random-string": ">=4.0.0",
  "crypto-js": ">=4.0.0"
}

AI-Optimized Messages

This plugin is optimized for ESLint's Model Context Protocol (MCP), enabling AI assistants like Cursor, GitHub Copilot, and Claude to:

• Understand the exact vulnerability type via CWE references
• Apply the correct fix using structured guidance
• Provide educational context to developers

// .cursor/mcp.json
{
  "mcpServers": {
    "eslint": {
      "command": "npx",
      "args": ["@eslint/mcp@latest"]
    }
  }
}

By providing this structured context (CWE, OWASP, Fix), we enable AI tools to reason about the security flaw rather than hallucinating. This allows Copilot/Cursor to suggest the exact correct fix immediately.
