Licensing class and script with 64bit Encryption (more Reliable)
This software component for MetaTrader 5 is built to enhance the capabilities of your trading environment. This library provides a collection of modular, reusable code. It is utilized by developers to organize common functions, allowing for the integration of complex logic across multiple Expert Advisors, indicators, or scripts without the need for code duplication.
How to Setup and Use Licensing class and script with 64bit Encryption (more Reliable)
1. Storage: Place library files in the MQL/Libraries directory to ensure they are accessible to your projects.
2. Implementation: Include the library in your code using the #import directive, ensuring you match the exact function names and parameters.
3. Compilation: Ensure the library is present in the directory before you compile your main EA or script, as the compiler links them during this phase.
4. Management: Keep libraries organized in sub-folders if you manage many custom functions to maintain a clean project structure.
Frequently Asked Questions
Q: What is a library file used for? A: Libraries store reusable code modules, allowing you to centralize common logic used by multiple EAs or indicators.
Q: Is a library executable? A: No, libraries are non-executable files containing functions; they must be imported into an EA, indicator, or script to function.
Q: Can I update a library while the platform is running? A: You should compile your EA or script after updating a library to ensure the latest code changes are integrated.
Description & Settings
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...
