I haven't been here long, but that's the best question I've ever read.

Did you ever hear about algoritm MD5, which guarantees an invariance of in advance given sequence of numbers on roulette?

Yes, I've heard of MD5. There are logos displayed at the casino touting this.

I emailed support yesterday - so far, no answer back.

MD5 is a hashing function.

Basically the principle between any hashing function is that if you pass a message:

e.g.,

Hello Bryan

through that hashing function it generates a hash, in this case:

8ed03a566c82a4f5d6a06f159b813179

This is a one-way function, which means that it is impossible to go from the hash back to the message. A key characteristic of it is that it is computationally infeasible to create a message to match a given hash, and moreover that if you change a single byte in the message, the hash will change completely.

So the hash for

Hello bryan is

eece70751d52bf0e715de9c49302875a

In this case, they say that you can get the md5 hash before the cards are dealt. I had a look, I pressed the Md5 button, and got the following hash (this is on free play)

d33fbea24d3dbaf3f3731fed023204ec

I played the hand, and then went back, and it gave me the deck ordering, plus a code word

deck = s8, c6, c7, c2, dA, s6, dJ, hK, sJ, d9, h2, c7, h3, h2, d2, d7, s10, d5, sJ, d10, d9, hJ, s10, d2, cA, h4, d5, c4, d3, dJ, hK, d2, hQ, d8, h5, c3, h2, hQ, d6, s2, dK, d4, hA, c10, hA, h6, d10, c4, d6, hK, sQ, h4, s9, s3, d2, d8, s5, sQ, s5, hA, cQ, dQ, c3, d5, sJ, h9, h9, s4, s8, h8, h7, s7, d5, h8, d4, sQ, dA, cK, c8, c2, s2, cJ, c5, h5, d3, sK, hK, s3, h2, hJ, d10, cQ, s4, c10, cK, s5, s9, d9, dJ, hK, c10, s6, cK, h9, d3, h6, dK, s8, dJ, c8, cA, d3, d6, c9, c2, s4, c4, cJ, h7, s2, s8, d6, sQ, hJ, sQ, dQ, h10, s6, dK, cK, dQ, sK, c9, c6, s6, c5, h3, c9, h5, cJ, d4, h8, c8, hQ, hK, d9, h5, dK, h2, s10, c3, cA, h6, h4, dJ, h3, sA, cJ, cJ, s4, s5, d4, d4, c9, h5, cQ, h10, hQ, h4, s8, s9, s10, hA, s6, h9, s3, dQ, sK, d7, c8, d8, sK, d7, s5, h8, h2, h3, sK, c4, h8, s2, d7, d2, sJ, cQ, dA, d8, dA, d10, h4, s9, d7, s10, c7, d3, c5, sJ, c9, d9, c5, c10, cJ, s5, c5, dA, d10, h3, cK, h6, dQ, sQ, cA, c6, s2, s7, hJ, s4, dK, cK, s4, sA, h6, c8, c10, hA, dA, s7, s3, s10, cA, h8, cA, d8, c7, c6, d5, d9, c6, c3, h9, hJ, dJ, h10, s9, s7, c7, c2, dQ, c8, sA, s7, d8, h6, d5, h4, c3, c5, h7, hQ, c9, cQ, sA, h9, d10, s8, h10, d2, d7, d3, sA, sJ, hJ, d4, h5, dK, h10, h10, d6, s6, s3, hQ, h7, sK, c4, h7, c2, s3, c7, s7, c2, c10, h7, s2, c3, c6, cQ, hA, h3, d6, s9, sA, c4; server code word = FEmgGE6DZ88E56s5CEYfrJhht4Ga3tQM

(the random code word completely removes any chance of any brute force attack on the hash)

I pasted that into here: http://pajhome.org.uk/crypt/md5/

Sure enough the MD5 hash comes back: d33fbea24d3dbaf3f3731fed023204ec

as stated before the hand

What does this mean?

Well, it means that the cards were determined before the deck was shuffled. This means that the casino cannot be dealing seconds.

This does not mean that they are not cheating: for instance, you could make the player's first card disproportionately likely to be a six. In other words: if you arrange the deck in a way that is deterimental to the player, then there is no protection.

They state that you can also cut the deck, which would make this less likely; however, I could not get the software to come up in English so couldn't work out how to get this to happen (the MD5 hash did not change).

So I did not prove to myself that the cards were fair with 100% certainty, and given that it is a Russian casino, the presumption is that it is NOT fair.

Anyway, it's quite a nice idea, and it is very possible they are legit, but having spoken to some Russian guys about the casino business, I would not advise using this or any other Russian casino without extreme evidence to the contrary.

[YuraK]

thelawnet your explanation is good .
About cutting - you tell to cut 5 cards then dealing will start from card 6 of the generated deck (s6 in your example). You can also pick up cards from the deck in any order, e.g. you can tell to deal card no. 10, then 5th, 21st ,54th, 23rd etc... Initial deck and MD5 signature remains unchanged. It makes really useless non-random deck generation.
You probably talked about Russian market some time ago, it become better each year...

Thanks thelawnet for the explanation!

Email came in over the weekend:

Dear Mr. Bailey,

We appologize for the delay with the answer. The game software of hibet.ru

So I'm assuming it's in-house.

[Seneka]

Could anybody tell me - why MD5 algoritm is not popular in European and American casinos?

Are there any casinos which use MD5 except for Russia?

[SlotMonster]

It was long time ago...but it's still interesting...don't you think so?
