I see you just started accepting CLAM, so thought I would give it a go.
I've not been able to figure out how to verify the server seed hash. I tried following the instructions on site, but it doesn't work.
What am I doing wrong?
Here's how the provably fair tab looks:
I had to inspect the element to figure out how many spaces were each side of the comma - it seems to be one both sides.
I wrote some PHP code to try to run the code you gave for the server seed hash:
// before playing, I was given a hash: 571FC0AE8E8C88567131A20B1480CBCD54F89E46B3218E70CE715176917672F1 and set a client seed: 54434
//
// after playing, I was given this:
//
// BET ID: 31337449
// USER: dooglus
// TIME: 2014-12-27 01:46:33
// Roll: 44.27
// GAME: 50.50
// BET: 0.0001
// MULTIPLIER: 2.000000000
// PROFIT: 0.0002000000
// Server Seed HASH: value="571FC0AE8E8C88567131A20B1480CBCD54F89E46B3218E70CE715176917672F1"
// Server Seed: value="230554171"
// Client Seed: value="54434"
// SECRET: value="b607147d108fd511516110602074c6a8"
//
// the page says that the server hash is generated like this:
// SHA256 ( $ServerSEED .' , '. $SECRET )
// I guess that's PHP:
//
$ServerSEED = '230554171';
$SECRET = 'b607147d108fd511516110602074c6a8';
print hash ( 'sha256', $ServerSEED .' , '. $SECRET );
// but that prints ee15a143cf6db5d129d1337ed2392370f3724448ac79c4d5d420e086226747e4 - so how do I get the 571F hash?
?>
but it doesn't work.
What does?
Edit: and where can I find the definition of the MersenneTwister class?
Edit2 [4 hours later]: I just found this on a different page:
It says you use MD5 and ' | ', whereas the other page says you use SHA256 and ' , '. But that doesn't seem to work either - you have two contradictory explanations, and they both seem to be wrong. Has anyone ever verified a single roll? If so, I'd like to know how!
Edit3: the published server seed hash is too long to be an md5 hash. I tried various ways of combining the server seed and the secret with sha256 but none worked:
