Passwords ka use 1000 years pahle se ho raha hain, for identifying ourselves to others and recent times me jada use ho raha hain computers mein. Simple concept hai information secret rakhne ke liye password ka use karte hain, Also used to “prove” identity. IT context me password 1960 me appear hua tha mainframe computers ke saat.

What Makes A Good Password?

Ek aacha password ek word ka ya ek phrase jisme 6 to 8 characters hota hai. But now minimum length guidelines hai. This is because of “entropy”. Jab password kee baat kare toh, Entropy password ki predictability ko measure karta hai. Iske peeche ka maths jada complex nahi hai, but let’s examine it with an even simpler measure: sometimes possible passwords kaa number referred to as the “password space”. Agar one-character passwords me one lowercase letter hoga then total 26 possible passwords hoga(a to z). By adding uppercase letters, 52 possible passwords tak increase kar sakte hai. The password space expands as the length is increased and other character types are added.

Jab website pe login karte ho toh wo password hashed me change ho jata hain and then stored on the site. This process is repeated. For example, Password hai  “Pa$$w0rd” then uska hashed value “02726d40f378e716981c4321d60ba3a325ed6a4c” yah hoga. When we calculate using the hash algorithm.
