I would use overload::eval to get at the obfuscated Perl code. As long as your custom Perl interpreter can load modules, I can load other modules into it, which replace eval with my own code to print out the decrypted code.

    I am not using Perl's eval method to do in-memory execution .. You can't do that

      Essentially without more details it simply going to be a case of people posting potential attack vectors, and you saying they don't exist within your solution. See also Re: Code hiding in Perl.

        The encryption is done through custom C executable and the execution of encrypted binary code can only be done through another C executable (dummy Perl interpreter) and it does in-memory execution like this. 

        perl_run(my_perl);
eval_pv(buffer, TRUE);
