Cum se calculează Password Generator

Ce este Password Generator?

A password generator creates cryptographically random passwords of specified length and character set, and calculates the entropy (strength) of the generated password.

Formulă

Entropy = L × log₂(N) bits

L: password length; N = character set size — password length; N = character set size
N: character set size — character set size

Ghid pas cu pas

1Entropy = L × log₂(N) bits
2L = password length; N = character set size
370+ bits is considered secure for most uses
4Longer is always stronger — prefer 16+ characters

Exemple rezolvate

Intrare

16 characters, all printable ASCII (95 chars)

Rezultat

Entropy = 16 × log₂(95) = 104.9 bits — very strong
