security - Embed secure layer into .EXE using C++ -


i started project friend of me , wanted create security application windows using c++. decided create program "lock" executable.

we found useful if send program else, store safely on usb/disk , learn more executables. program imbed 'host' executable , encrypt programs binary. then, when program launched, our imbedded program asks password , unlocks/decrypts without need of original program, unlock on computer without needing original program.

here question: "how embed security layer existing program?" , "is possible?".

also, if such program exists, can possibly find it?

thanks in advance!

'hasOwnProperty' in javascript -

i use obj.hasownproperty judge whether object has property, when replaced obj[prop] !== undefined , not normal implementation, ask, why behind method can not use it? object.hasownproperty(prop); object[prop] !== undefined; obj[prop] !== undefined wrong 2 reasons: you can explicitly set property undefined , obj[prop] = undefined; . obj.hasownproperty(prop) return true in case. obj[prop] follow prototype chain, return property that's inherited. obj.hasownproperty(prop) returns true if property exists directly in object, returns false inherited properties.
