Try this one:

You concatenate the strings, meaning you combine them into one. Exactly as it is shown there.

Paste this into the box in the sha256 hash calculator

1631|e4e93da14e26c6d9a1e22f6d0e63c52d

And your result should be

25957aaf0a91ed9faaa0b4622f890a98eba174d40513cb0344ffc01a4bb55fce

Don't worry, we were all noobs at one point. But that you admit you are a noob and then accuse several game sites about their provably fair implementation does not look good for you.

I hope that some day you will understand.

You can also try any other SHA256 calculator. You will get the same result.
