Password Strength Checker ek password ko kaise score karta hai?

Yeh aapke password ki length aur character pool se estimated entropy ko structural weaknesses ke penalties ke saath combine karta hai — common passwords, single character classes, repeats, sequences, aur keyboard walks — ek 0-4 score aur ek one-word verdict produce karne ke liye.

Yahan entropy bits mein asal mein kya matlab rakhti hai?

Entropy bits mein roughly password ko brute-force karne ke liye zaroori guesses ki sankhya ka log2 hai: length times character pool ka log2. Zyada bits ka matlab exponentially zyada possibilities, isliye 60+ bits 30 se meaningfully zyada strong hai.

Crack-time estimate kaise calculate hota hai?

Yeh average number of guesses (entropy dwara implied search space ka aadha) ko lagbhag 10 billion guesses per second ki ek assumed attacker speed se divide karta hai, phir hours, years, ya centuries jaisi ek readable unit par round karta hai.

Yeh password checker kaunse weak patterns detect karta hai?

Yeh aise passwords flag karta hai jo bahut chhote hon, sirf ek character type use karte hon, bahut common passwords ki ek chhoti embedded list se match karte hon, ya repeated runs, abcd jaise ascending ya descending sequences, aur qwerty ya asdf jaise straight keyboard walks rakhte hon.

Kya is checker mein ek real password type karna safe hai?

Analysis poori tarah aapke browser mein hota hai aur password kabhi kahin nahi bheja jaata, isliye test karna safe hai. Phir bhi, ek general habit ke roop mein, kisi bhi web page mein jis par aap poora bharosa nahi karte ek live production password paste karne se bachein.

Kya yahan ek high score guarantee karta hai ki mera account secure hai?

Nahi. Ek strong score ka matlab password khud guess karna mushkil hai, lekin account security per site unique passwords, breach exposure, aur two-factor authentication par bhi depend karti hai. Score ko guidance maanein, guarantee nahi.

Password Strength Checker

Test karein ki ek password kitna strong hai, uski entropy aur estimated crack time dekhein, aur plain-English weaknesses paayein — sab aapke browser mein.

Password Strength Checker aapke password ko poori tarah aapke browser mein analyze karta hai. Jo bhi aap field mein type karte hain woh aapke device par rehta hai — yeh kabhi upload, log, ya ArrayKit ko nahi bheja jaata.

Password Strength Checker ke baare mein

Password Strength Checker maapta hai ki ek password guess karna kitna mushkil hoga aur kyun samjhata hai. Ek type ya paste karein aur yeh ek 0-4 strength score, estimated entropy bits mein, aur ek rough offline crack time compute karta hai, phir break down karta hai ki aapne kaunse character classes use kiye — lowercase, uppercase, digits, aur symbols. Yeh concrete weaknesses bhi flag karta hai: aise passwords jo bahut chhote hon, sirf ek character type use karte hon, ek bahut common ya breached password se match karte hon, ya repeated characters, abcd jaise sequential runs, ya qwerty jaise keyboard walks rakhte hon. Ek reveal toggle ke saath ek masked field aapke kaam karte waqt aapka password chhupa rakhta hai. Yeh ek account ya ek signup form harden karne wale har kisi ke liye bana hai. Har calculation aapke device par chalta hai — password kabhi browser se bahar nahi jaata.

Features

Kisi bhi password ko 0 (very weak) se 4 (very strong) tak score karta hai jaise aap type karte hain
Character pool aur length se entropy bits mein estimate karta hai
Plain language mein ek rough offline crack-time estimate dikhata hai
Composition break down karta hai: use kiye gaye lowercase, uppercase, digits, aur symbols
Too-short passwords aur single-character-class passwords flag karta hai
Common ya breached passwords, repeats, sequences, aur keyboard patterns detect karta hai
Ek reveal toggle ke saath masked input taaki password chhupa rahe
Poori tarah aapke browser mein chalta hai — password kabhi upload nahi hota

Password Strength Checker kaise use karein

Password ko masked field mein type ya paste karein
Strength score, entropy bits mein, aur estimated crack time padhein
Confirm karne ke liye Reveal use karein ki aapne password sahi type kiya
"What we found" ke neeche listed har weakness fix karein aur dobara check karein

Example

Input

password

Output

Score 0 / Very weak · flagged: very common password · crack time: instantly

"password" har breach list par hai, isliye yeh ek dictionary attack mein turant gir jaata hai.

Common errors aur troubleshooting

Ek lamba password phir bhi low score karta hai. — Sirf length kaafi nahi. "What we found" list check karein — ek common word, qwerty jaisa ek keyboard walk, ya ek repeated run score ko neeche rakh sakta hai. Character types mix karein aur predictable patterns se bachein.
Entropy high dikhti hai lekin score capped hai. — Entropy random characters maanti hai. Agar password ek common se match kare ya ek single character class use kare, to score jaan-boojh kar kam kiya jaata hai kyunki ek real attacker use aankh moondkar brute-force nahi karega.
Crack time bahut optimistic ya bahut pessimistic lagta hai. — Yeh ek rough estimate hai jo ek weak hash ke against lagbhag 10 billion guesses per second par ek fast offline attack maanta hai. bcrypt jaise slow, salted hashes kaafi zyada time lete hain; ek leaked plaintext koi time nahi leta.
