Simple_SHA256

This is a simple C++ program that takes an input string from the user and computes its SHA256 hash using OpenSSL.

Features

• Accepts user input from the console.
• Computes SHA256 hash using OpenSSL.
• Displays the hash in hexadecimal format.

---

Requirements

• C++ compiler (e.g., g++)
• OpenSSL development libraries installed

Example Output

Enter a string to hash using SHA256: Hello123
SHA256 hash of "Hello123":
1ad8b9e77c93d2149637c21ad61b0beff86b6a34cc0e546139db0d1cf0c932e0

Enter a string to hash using SHA256: 0
SHA256 hash of "0":
5feceb66ffc86f38d952786c6d696c79c2dbc239dd4e91b46729d73a27fb57e9

Note

This program uses SHA256 from OpenSSL. The same input will always generate the same hash (i.e., it's deterministic).
