This is a library of SHA-256 hashes.
There are NO original files hosted here, only the hashes organized in json.

What is a SHA-256 hash?
It in short is a code that is mathematically created from a file’s data.
That code will always be the same unless something in the file’s data is changed.

What can you do with it?
It’s used to verify if a file has or has not been modified.
If the SHA-256 hash of 2 files match, then both files are identical.

You can use libraries like this one to check if the files you have are the same as the original.
