Re: A89: The logic behing signined and unsigned programs!




Oh, I'm not saying you COULD sell it to people, unless they are stupid
and haven't noticed the presence of linkports on their calcs, I'm just
saying it is LEGAL to.  And as for encrypted, piracy-protected
programs... if you have both the ROM that checks the software and the
software being checked, I don't see how you could stop a determined
hacker from figuring out the key.  It's gotta be there somewhere in one
form or another if it is checking its validity, else how would it check
it?  Or at least that's how it seems to me.
