Topic: How can I create server seed for a gamble game? (Read 1280 times)
If you have to ask this question, this probably means you shouldn't be running a game like dice. I get low-level hacking attempts everyday towards my server, just a warning if you can't defend this attacks you will be run down very fast.
Generate random values using Node.js crypto module
Alternative to the above mentioned options might be generation of random values using crypto.randomBytes(size, [callback]) method from crypto Node.js module. randomBytes returns a buffer with randomly generated bytes. It can work asynchronously (when callback function is provided) or synchronously (only size parameter is provided). Returned buffer can be transformed using different encodings to get required format.

Thanks friends. I'm not using php so that link is not for me. I will go with sha512 I guess.
Yes, but what random number generator are you using?
Some can allow hackers to gain advantage above house edge.

How are you generating the server seed? I really hope that you are using something that is server sided.

I have run a casino and sell scripts to many people. If you want a provably fair system with an automatic secret generating script, pm me. I could help you out.
You need crytpographically secure random func, many standard rand funcs are not.
If using PHP server side then take a look at this:
http://php.net/manual/en/function.openssl-random-pseudo-bytes.php
Then hash it, if you want to be really tight (maybe overkill for gambling with low max bets) then use multiple hashes of whirlpool.

Normally the way I have seen it done is take a random alphanumeric string.
Then hash it in SHA512 or equivalent and show it to users.

Fixed.
