Frequently Asked Questions

Evidence-based insights on mechanics, entropy calculation, and password safety.

How is entropy calculated for passwords?
Password entropy in bits is calculated as Length × log2(Pool Size), representing the mathematical difficulty of guessing the exact combination in binary attempts. A 20-character password using all 94 ASCII symbols provides approximately 131 bits of entropy.
What hardware scales are evaluated for crack times?
Estimates assume a Consumer Desktop (10^9 guesses/sec), a Distributed Botnet (10^12 guesses/sec), and a State-Level Supercomputer cluster (10^16 guesses/sec).
Are generated keys transmitted over the network?
No. Keys are generated exclusively within your browser using the window.crypto CSPRNG API with zero network calls, guaranteeing complete data sovereignty.
What is the recommended entropy threshold for master passwords?
A minimum of 75 bits of entropy is recommended for master passwords and encryption keys, which typically requires at least 16 to 20 randomized mixed characters.
