Why do people come up with the same discussions every week on the same thread? The random number generation used in just-dice is secure. it takes entropy from OpenSSL's
RAND_bytes function which is as secure as you can get without resorting to custom hardware - if you're worried about OpenSSL's RAND_bytes function then be worried about the ephemeral keys used to secure the SSL you use to talk to your bank.
Once it has these random bytes (the seed) it then uses HMAC_512 to generate all the random numbers for the player. This is predictable because the game has to be provably fair, but it is not possible to determine or predict anything about the output of the function without knowing the server seed (see above).
Thanks for the information, finally a useful post.
On the page it says
Your client seed for that server seed was
Does anyone know if it actually means that the client seed is used as a seed for the server seed or if its just a mistakable formulation.
Also I'd like to know how the server seed for each user is saved. There's still the possibility of an SQL injection for example.
