The Karuvigal Security Standard

In an era of relentless data breaches, relying on server-side generation is a risk you shouldn't take.Karuvigal prioritizes zero-trust architecture. Our tools are built to function without ever transmitting your generated secrets.

True Client-Side Generation

We leverage the Web Cryptography API (window.crypto) inherent in modern browsers. This provides a source of entropy that is mathematically superior to standard pseudo-random number generators. When you click “Generate”, the process executes 100% on your CPU, and the result exists only in your RAM until you close the tab.

Defense in Depth

  • Entropy First: We focus on bit-strength, ensuring passwords are mathematically resistant to brute-force.
  • No Logging: Since no request is sent to a backend, there are no server logs to compromise.
  • Transient State: Your data survives only as long as your session.

Frequently Asked Questions

Is this password generator safe?

Yes, absolutely. The passwords are generated locally in your browser using your device's cryptographic libraries. Nothing is ever sent to our servers, ensuring your data remains private and secure.

What makes a password strong?

A strong password is long (at least 12-16 characters), complex (mix of uppercase, lowercase, numbers, and symbols), and unpredictable. Avoiding common words, personal information, and sequential patterns (like 1234) is crucial.

Should I valid my password with a strength checker?

It is recommended to check the strength of your passwords to ensure they are resistant to modern cracking techniques. Our Strength Checker tool analyzes entropy and estimates cracking time to help you improve your security.

What is a passphrase?

A passphrase is a sequence of random words (e.g., 'CorrectHorseBatteryStaple') that is easy for humans to remember but hard for computers to guess. They are excellent alternatives to complex random strings for passwords you need to type frequently.

How often should I change my passwords?

Modern security guidelines suggest changing passwords only when you suspect a breach. It is more important to use unique, strong passwords for every account and enable Two-Factor Authentication (2FA) where possible.
