SHA-256 is one of the most popular hash algorithms around. Here I'll break down what is is, when you would use it in the real world, and how it works.

You explained in this video how SHA-256 is used and what it is used for, not how it works and how it is generated.

Thanks for this video. Something you said was that SHA-256 is very fast, so it is bad for password storing because people could just generate new fingerprints very easily. But if it is already irreversible, and data is scrambled deterministically, why does this matter? Maybe I am understanding this wrong.
