I need to know if there's a readily available unpacker (official or otherwise) for the executable archiver at http://www.bitsum.com/pecompact.php . I was thinking of using it for archiving my application and also deterring crackers as much as possible. The lack of such a utility (unpacker) would make it a little bit harder to crack the program.

Also, I was reading something about making UPX unable to decompress an archive by changing some header information:

"If you delete the UPX markers from the beginning of a compressed exe the built in UPX decompressor won't work any more... basically just use a file editor like FrHed.exe to overwrite these markers...just remove any mention of UPX and the file won't decompress any more"

Is this possible to do for PECompact, so that the archive itself looks like it's been packed with another exe archiver?

Thanks for the links :)

Do you know for a fact that there is an unpacker for the latest version of PECompact 2.8x and above? I've seen a lot of conflicting information on various forums.

Also, what do you think about the other part of the question?

I can find unpackers up to 2.79 but nothing above that.

One link had another link to a 2.82 unpacker download version but didn't follow it.

You can muck up the header as long as it's not used elsewhere.

But a determined hacker may just throw all versions of unpacker at the target file and tell it to ignore the mucked up header.  They can still determine how it's compressed in one form or another by examining the code.
