Question

I have written a small app in C++ consisting of a single EXE file.

I want to put in its “about” dialog the md5sum of the executable itself. It should be embedded statically into the executable (so that can be seen from hex editor), rather than computed on the fly.

Answer 1

As both @Shi & @matthewdaniel have already said, this can’t be done directly.
However a couple of workarounds are possible:

• Calculating MD5 of your application, and packaging your executable inside a container app that will simply extract it and check it’s MD5
• Compiling your code and hashing only the code segments or other segments (except the Data), and than adding the MD5 check code. This will work as the MD5 string will be stored in the Data segment keeping the validity of the precalculated hash of any other memory segment valid.
