EA Key - Any example how to validate a key

Hi everybody!

I'm looking for some example about how can I check a key of my EA.

For exemplo:

I have in my EA a extern param (Key) and when the person get this EA, this person tell me the account number and I generate a serial key.
But the problem is how can I check this key with a webservice or some thing like that?

Any example?

Thanks a lot

I copy and paste here:

REAL CORRECT WAY TO DO IT:
For online-services, life is a bit simpler, since even with the binary file you need to authenticate with their servers to make any use of it (eg. have a WoW account). The CD-key algorithm for World of Warcraft - used, for instance, when buying playtime cards - probably looks something like this:
1. Generate a very large cryptographically-secure random number.
2. Store it in our database and print it on the card.
Then, when someone enters a playtime-card number, check if it's in the database, and if it is, associate that number with the current user so it can never be used again.

For online services, there is no reason not to use the above scheme; using anything else can lead to problems.

Very nice, thks

My recommendation is to base your EA validation system on : MQL4 + http web request + php + MySQL database. It works as follow:

1. At EA purchase your php (webhook) script generates automatically a long and random licesne key "LicKey".
2. This webhook php script also updates MySQL database with this new "LicKey" and buyers email (so you can see which LicKey belongs to what buyer)
2. The same php script mails the buyer and sends him this "LicKey"
3. Then the EA user needs to enter this LicKey as 1 of the EA parameters
4. On init() function the EA first connects with the remote database and checks if the license key is valid
5. On the first EA run the license key is paired with the users account number (so the license key, even if stolen, only works for original buyer)

I hope it make sense, if not contact me I have the whole solution implemented many times.
