Miscellaneous tools cover a range of utilities: password entropy scoring, hash generators, random number generation, ASCII conversion, and other niche calculators.

Fórmula

Password entropy: H = log₂(Nᴸ) = L × log₂(N)

H: log₂(Nᴸ) = L × log₂(N) — log₂(Nᴸ) = L × log₂(N)
L: password length — password length
N: character set size; L = password length — character set size; L = password length

Guía paso a paso

1Password entropy: H = log₂(Nᴸ) = L × log₂(N)
2N = character set size; L = password length
370+ bits of entropy is considered secure for most purposes
4Each additional character multiplies the search space by N

Ejemplos resueltos

Entrada

12-char password, upper+lower+digits+symbols (95 chars)

Resultado

Entropy = 12 × log₂(95) = 78.8 bits — strong
