PLYour Bank Doesn’t Know Your PIN! 🏧🤫 (Hashing)
Here is a scary thought: If a hacker breaks into the bank's database, will they see your PIN? 😨
The answer is NO. Because even the bank doesn't know it!
This is the magic of Cryptographic Hashing. 🛡️
Here is how the verification process works:
1️⃣ The Setup: When you create your PIN (e.g., 1234), the bank doesn't save "1234". They put it through a One-Way Function (Hash Algorithm).
They only save that scrambled mess.
2️⃣ The Check: When you go to the ATM and type 1234:
The ATM doesn't send "1234" to the server to check.
It runs the same hashing formula on what you typed.
3️⃣ The Match: It compares the New Hash with the Stored Hash.
If the scrambled codes match, the PIN must be correct! ✅
