Topic 1: Security - Strong Passwords Secure Way.

Instead of storing as plain text, Convert the password to a fixed length encrypted string using hashing algorithm.

Problem:
If you have same password for multiple users: the encrypted string will be same.

To Solve this, We need to ensure every hash is unique.

Adding a Salt, which is a unique key to the hashing algorithm can be used only by that username.

Final:  Even if multiple users chose the same password, their hash values would not be the same.


Advice from Security Researchers: Not to store the SALT in Database.

It should dynamically apply based on initial character of Original Password.
