Happy New Year to All,
I am basically considering making a BPL my license file.
I have some questions regarding hacking a BPL.
Is it as hackable as an EXE file?
If I put license information in a BPL, would it be just as vulnerable as an
EXE?
There are commercial licensing/software protection products out there, like
WinLicense www.oreans.com, but can you protect BPLs as well? I see Oreans
has a WinLicense DLL Control version which may be more along the lines of
what I am looking for but I am not sure.
This topic area is new to me, so bear with me, while I ask dumb questions.

Downloaded it. Tried it. Looks like these guys have figured it out at
great depth.

A BPL is nothing other than a dll. In addition to a dll it has an
initalization and finalization procedure called
'@YourBplName@initialization$qqrv' (and the same for the finalization
proc). The classes are encoded via exported function calls these
function calls are encoded such that the loading mechanism can construct
delphi classes out of it.
You can try it out yourself by opening a bpl in the Dependecy Walker tool.
kind regards
Mike

specific exported functions that the VCL looks for at run-time. Otherwise,
it is a normal executable file like any other, and can be debugged and
disassembled just as easily.

by regular methods I used for dlls.
