Password Utilities

Analyze Password

Evaluates password strength across multiple security dimensions including entropy, character diversity, and common attack vectors. Available through MCP in Cursor and other AI editors, or via REST at GET /v1/password/analyze. Returns detailed analysis including strength score, estimated crack time, and specific recommendations. Uses industry-standard algorithms to assess real-world password security.

API Endpoint

GET /v1/password/analyze

Code Examples

curl "https://tinyfn.io/v1/password/analyze" \
  -H "X-API-Key: YOUR_API_KEY"
const response = await fetch('https://tinyfn.io/v1/password/analyze', {
  headers: { 'X-API-Key': 'YOUR_API_KEY' }
});
const data = await response.json();
console.log(data);
import requests

response = requests.get('https://tinyfn.io/v1/password/analyze',
    headers={'X-API-Key': 'YOUR_API_KEY'})
data = response.json()
print(data)

FAQ

How does the password analyzer calculate strength scores?

Uses entropy calculations, character set diversity, length analysis, and checks against common patterns. Combines multiple metrics into a normalized score with specific weakness identification.

Can I analyze passwords in MCP tools like Cursor without exposing them?

Yes, the analysis runs locally through MCP so passwords aren't transmitted to external services. Perfect for security audits in development environments.

What specific vulnerabilities does it detect in passwords?

Identifies dictionary words, common substitutions (@ for a), keyboard patterns, repeated characters, and estimates resistance to brute force and dictionary attacks.

Does it check against known breach databases?

No, it performs structural analysis only. It evaluates pattern strength, entropy, and composition without checking against breach lists for privacy reasons.

What's the difference between entropy and strength score?

Entropy measures theoretical randomness in bits, while strength score combines entropy with practical attack resistance including pattern detection and real-world cracking scenarios.
