entropi (bits) = Length × log₂(Pool Size)

Pool Size = 26 (lower) + 26 (upper) + 10 (digits) + 33 (special) = 95 max

Score based on: length (50%), case mixing (15%), digits (15%), special chars (20%)

Pertanyaan Umum

How is kata sandi kekuatan calculated?

kekuatan is calculated menggunakan entropi (bits of acakness), length, character diversity, and pola analysis. Higher entropi and diverse characters result in stronger kata sandis.

What is a good entropi score?

entropi above 60 bits is good, above 80 bits is strong, and above 100 bits is very strong. A 12-character mixed-type kata sandi typically scores 70+ bits.

Mengapa panjang lebih penting daripada kompleksitas?

Length exponentially increases kata sandi kekuatan. A 20-character lowercase-only kata sandi (95 bits) is stronger than a 10-character mixed-type kata sandi (66 bits). Length always wins.

Is this alat storing my kata sandi?

No. All analysis happens in Anda browser. For security, consider typing a similar kata sandi rather than Anda actual one.
