Hi, im just trying to figure out how to properly check a sites provably fair system but it's not matching up for the first step and im not sure if if i'm making a silly error or if their system is broken.
So their first step is
Step One, Verifying the Server Hash:
We need to now verify the server hash was created using the server seed and client seed.
Lookup "Free HMac Generator" on Google, or use this one.
Inside the box that tells you to input your message, paste in the server seed. (Be sure it is the seed and not the hash).
In the box that asks for the secret, input the client seed.
Choose SHA512 as the digest algorithm.
Select Compute HMAC
You should see that the hash generated matches the server hash above.
The hash is generated by combining the client seed and server seed, so if the hash is the same, that means the seeds were never modified.
this is the seeds/hash provided by them

however when i hash the client+serverseed i am getting a1fa2bd2f869638fb819a099b38151bc47037ae0bc89e27da521922fc32d690367c217b37ad651d bd9d2de43867048bf22f25c398c33d0f6aa8c3c335af29111
am i missing something?
