Security Validation for Password Generators

When to Use

Use this skill when implementing, reviewing, or auditing security measures for password generation and handling.

Security Checklist

1. Randomness

   • Use cryptographically secure random number generation (crypto.getRandomValues())
   • Never use Math.random() for password generation

2. Memory Handling

   • Avoid storing generated passwords in global variables
   • Clear password from memory after copy operation
   • Don't log passwords to console in production

3. Client-Side Security

   • Passwords should never be transmitted to a server
   • Use HTTPS if any network operations occur
   • Implement Content Security Policy headers

4. Input Validation

   • Validate password length is within acceptable bounds (1-128 characters)
   • Sanitize all user inputs
   • Prevent XSS in password display

Validation Commands

# Check for console.log statements with sensitive data
grep -r "console.log.*password" src/

# Verify crypto API usage
grep -r "Math.random" src/  # Should return no results
