Re: How to prevent sensitive information is displayed when the extension 'exe' is modified to 'txt' on windows?

[FrankLike via Digitalmars-d-learn]

What you want is some kind of code obfuscation. The easiest 
thing for
you is to use exe compression. It is not going to stop a 
dedicated
attacker, but ordinary people will not be able to extract any
information from it.

Yes,if I can't get some tools  from dmd or ldc,then I should look 
for some kind of code obfuscation.

Thank you for your good idea.
