mIRC scripting is meant to be open source. If you encrypt it, people will not want to use it because it cannot be verified to be safe. There is nothing wrong with letting people edit your script so that it suits their needs. You aren't getting paid for it and even if you do encrypt it, you still won't get paid for it because others can just as easily make the same script for free. Encrypting scripts is a waste of time and effort and will just make your script unpopular.
