CSPRNG Password Foundry

Generate true cryptographically secure random passwords using hardware-backed Web Crypto entropy.

Configuration & Charsets

🛡️ Generated using uniform rejection sampling over crypto.getRandomValues, eliminating modulo bias and guaranteeing that every selected charset is represented.

Generated Passwords

Entropy & Crack Resistance

Entropy measures the unpredictable complexity of the generated password:

  • > 80 bits (Strong): Mathematically uncrackable by modern supercomputers and GPU clusters for centuries.
  • 50–80 bits (Fair): Adequate for standard consumer web accounts.
  • < 50 bits (Weak): Vulnerable to dictionary and high-speed brute force attacks.
