About this video
The SHA (Secure Hash Algorithm) family is one of the most widely used cryptographic hash standards in the world.
But what is the difference between SHA-1, SHA-2, and SHA-3?
In this video, we explain:
What SHA stands for
Why SHA-1 is no longer considered secure
Why SHA-256 (SHA-2) is widely used today
Why SHA-3 was introduced as an alternative design
You will understand how hash standards evolve over time and why cryptography must adapt to increasing computational power and new attack techniques.
This explanation focuses on conceptual clarity and comparison, without diving into internal compression functions or mathematical details.
