[GoLANG] SimpleLicense Go Based Licensing System - SIM-297877 - Apr 15, 2017
SimpleLicensing; https://github.com/SaturnsVoid/SimpleLicensing
A VERY BASIC Go Based Licensing System for Digital Rights Management
Included is a simple Server i built to handle the backend things, a database.sql file (you need to import into MySQL), the main package (License.go), and a example client show you how it could be used.
This is something i put together fast, but it works. Feel free to use it as you please.
How it Works
Server creates a table for license email, license, experation date, and ip
Server generates a license key (XXXX-XXXX-XXXX)
Server encrypts it using your Servers key (Generated on setup) and server gives you it
You give client to buyer/user with license.dat file that contains the encrypted license
Client connects to license server, sending its license.dat
Server trys to decrypt liscense.dat and comapire with any in database
If Server finds the key it check to see if the license is expiered and update last IP
If not expired client runs, else it will tell them its expiered and closes
NOTE: The client must have an internet connection to the license server!
Licensing.go
Licensing can be called at anytime in your program, Just import and select to settings for it. Its a simple one line command.
Code
Licensing.CheckLicense("{LICESNESSERVER}", {USESSL}, {SILENT}){LICESNESSERVER} = http://127.0.0.1:8080
{USESSL} = true or false to use SSL (Your server will need this setting too).
{SILENT} = Show messages or not.
Server:
Ability to add new licenses to database
Config Setup Tool
Ability to remove liceses from database

Nice contribution, I like it, shame the server isn't in PHP so I don't have to buy a VPS ðŸ˜

You have plenty of options when it comes to hosting Go applications. Heroku free tier is plenty enough. Loads of cheap VPS options
