What is the problem with HMAC-SHA512? If there is no problem with it, why use a weaker alternative?

Speed? (No seriously.) You know what, maybe it was just a dumb question, who is going to notice the speed difference even when you have a few thousand players online at the same time on one server. But I had to ask it anyway. I did some quick research, and I think I won't go with MD5 or SHA1 at least.

Someone else made this speed test on the hash functions:

Code:
MD5     10.275190830230713, 10.155328989028931, 10.250311136245728
SHA1    11.985718965530396, 11.976419925689697, 11.86873197555542
SHA256  16.662450075149536, 21.551337003707886, 17.016510963439941
SHA512  18.339390993118286, 18.11187481880188,  18.085782051086426

atodorov.org/blog/2013/02/05/performance-test-md5-sha1-sha256-sha512/

And there's an older one here: http://www.cryptopp.com/benchmarks.html

The HMAC, if I understand it correctly, does two hashing calculations. So if MD5 = 20, and SHA512 = 36 ... (Okay okay, maybe it's a really dumb question.)

Quote
The main statement hashes all 10000 entries one by one. This statement is executed 1000 times in a loop, which is repeated 3 times.

So if I understand it correct it takes 18 seconds to make 30,000,000 SHA512 hashes according to that test? That's like 0.000006 second/hash? Sure MD5/SHA1 is 2x faster, but still it's basically nothing.

Better make sure your server, database, code (including client-side), etc. are all good than fixing non-issues :p

Dicebitco.in? its not safe after the issues. I would rather stay away from it

I dont think this thread was saying anything about the safety of the site, just what it's coded in..

I think a simple PHP-MySQL dice site may run fine on amazon cloud with real time update achieved by Ajax. All those node.js, socket.io seems redundant !!!

No, AJAX would be terrible, you would have A LOT of requests, basically every second. You really should use a socket for that.

However, you can definitely make a socket server in PHP. There are some libraries for it too: Ratchet, React, Wrench, PHudBase, PHPws, etc.

A socket is an open connection between the client (browser) and server with bidirectional communication. If you make a bet, you send the info through the socket (and you get the result) and if others bet you get the bets from there. So it's all real-time, you only connect once. There are different libraries/servers for this, Socket.io is a popular one made in node.js. Perfect for a dice site.

An alternative is indeed getting new data with AJAX requests. With that, the browser would make a connection/request every x seconds to see if there are new bets. Obviously for a dice site this would be pretty terrible and give big lag and other problems. However AJAX is useful for other purposes.

I was checking the All Bets section of www.onedice.me ...is not this data refreshing is done through Ajax ?

Any ideas on where the most gambling sites are hosted? Most of them use CloudFlare so you can't easily find the actual hosting provider.

The other question is, what servers are these sites using? Where are those located? How much? What's a good domain name? (I mean, maybe, the extension.)

Obviously, some of them are on a dot com, but is that really a good idea or would something else be better. (This is to avoid certain governments from seizing the domain names.)

Well, for example pocketdice.io sends a PHPSESSID cookie, so it's safe to say they use PHP ( https://pocketdice.io/index.php works too Wink). Besides that, you can easily see the socket.io socket.


A socket is an open connection between the client (browser) and server with bidirectional communication. If you make a bet, you send the info through the socket (and you get the result) and if others bet you get the bets from there. So it's all real-time, you only connect once. There are different libraries/servers for this, Socket.io is a popular one made in node.js. Perfect for a dice site.

An alternative is indeed getting new data with AJAX requests. With that, the browser would make a connection/request every x seconds to see if there are new bets. Obviously for a dice site this would be pretty terrible and give big lag and other problems. However AJAX is useful for other purposes.

If the site is coded in Java, can the use of Java threading solve the problem of real time update ?

Busy gambling sites need to provide high security as well as serve high traffic. In which language today's top sites are coded ? Which DB are they using ?

I'm listing a few sites below. Please post if u know about their configuration. If u know about a site which is not in the list, please post that too...

Oops... that was my editing mistake. I forgot to change the first column while editing the table for PocketDice.io.

@dogedice.me It is nice to see U here. Care to tell us the column values for dogedice.me/bitdice.me ?

I use tubesock to hijack rack and implement WebSockets in RoR, client code is my own with re-connection and error handling.

I do not have any front-end as it's single page app, JavaScript is written with CoffeScript and its pure jQuery with Bootstrap.

Hey, why there's second BitDice.me with PHP settings? That's ain't true Smiley

Oops... that was my editing mistake. I forgot to change the first column while editing the table for PocketDice.io.

@dogedice.me It is nice to see U here. Care to tell us the column values for dogedice.me/bitdice.me ?
Thanks Smiley

I use tubesock to hijack rack and implement WebSockets in RoR, client code is my own with re-connection and error handling.

I do not have any front-end as it's single page app, JavaScript is written with CoffeScript and its pure jQuery with Bootstrap.

I'm not very familiar with some of the technologies U r talking about. I have updated your row with what I understood. Please let me know if those are fine...

It'd be great to know which DB U r using here...

Busy gambling sites need to provide high security as well as serve high traffic. In which language today's top sites are coded ? Which DB are they using ?

I'm listing a few sites below. Please post if u know about their configuration. If u know about a site which is not in the list, please post that too...

Following table is updated as per latest data found in this thread...

BitDice.me & bitdice.me are the same Smiley

As main storage I use MySQL, Redis is being used to all realtime data & caching.

a lot of high end scripts are compiled to protect the companies IP work

so they say what they use, but inside can have a hybrid of languages and often due if you actually get to the source

Do u hav experience in running a real gambling site ? If yes, can u plz tell us the concurrent connections it experiences on an average ? By concurrent connections here I mean the real time visitors shown by Google analytics.
