Licensing class and script with 64bit Encryption (more Reliable) - libreria per MetaTrader 5

This class loads a licensing file by reading 64bit encrypted account data from a license file into an account array for the purpose of licensing.

(256 bit Encryption method I last posted, fails decryption on certain strings hence why this method more reliable)

The Class is initialised with a Filename, a Master Key (m_hkey -> can be a secret key of your choice, its hard coded here) and whether the file needs to be saved in the common folders or not.

Important Methods:

m_Write(string m_Acc  = "", string m_Broker = "") - Adds a a new account to the licensing file...

(we use this to make a simple script to add new accounts to the licence file. directly in Mt5 / Mt4)

m_LicenceFound(string m_Broker="", string m_Acc="",string m_Server="") - Checks the array of accounts from the license file to see if there is a matching and returns a bool based on it. The broker has to match, and then either the m_Acc (Account name) or the Server can match for licence found to return true...

And finally there are two public functions available for encrypting and decrypting strings using 256 bit encryption... (if needed by user)

The included sample script file creates a license file using above class.

The script will append new account licences to the specified file...
