How does this checker work?
🔒 Your privacy is absolute
Your password is analyzed entirely in your browser using JavaScript. It is not sent to any server, not stored anywhere, and not transmitted over the internet. You can verify this by disconnecting from the internet — the tool will still work.
⏱️ How is the cracking time calculated?
The calculation is based on:
- Character pool: how many different characters are possible (lowercase = 26, + uppercase = 52, + digits = 62, + symbols = 95).
- Length: each additional character multiplies the combinations exponentially.
- Attack speed: we assume 100 billion attempts per second (specialized cracking hardware such as GPU clusters).
- Formula: Combinations = (character pool)^length. Time = combinations / attack speed.
📊 What is entropy?
Entropy measures the "randomness" of your password in bits. The more bits, the harder it is to crack. As a reference:
- Less than 28 bits: very weak (cracked in seconds).
- 28–35 bits: weak (minutes to hours).
- 36–59 bits: moderate (days to months).
- 60–127 bits: strong (years to centuries).
- 128+ bits: very strong (practically impossible).
🔑 What makes a password secure?
- Length: at least 12 characters, ideally 16+.
- Variety: mix uppercase, lowercase, numbers, and symbols.
- Randomness: no dictionary words, names, dates, or patterns.
- Uniqueness: a different password for every account.
