Assume I created an archiving tool and a user wants to extract some
files from an archive into a directory one hasn't got write

alert sheet informing the user of "permission denied" error. But
imagine that instead of that, a standard Mac OS X authentication
dialog appears, asking for admin password in order to complete the
operation (with prior explanation of why that is necessary). Of
course, if the user is suspicious, he/she can click "Cancel", in
which case the "permission denied" error would appear as intended.
Do you think this is a good idea?
Why not? Finder already does this if you try to copy something into a
folder and you don't have write permission in that folder.
On the other (negative) side, I'm aware many people wouldn't trust
giving admin password to my application,
Really? It's been my experience that, even with the additional
requirement of entering a password, most users do not think critically
about multiple choice alert panels. People tend to go onto auto-pilot
and just click "OK" on all of them without reading or thinking about
them. They're better than nothing, though.
some may think that I faked authentication panel,
This is a possibility, though highly unlikely. I have yet to see
someone even try making a phishing panel on Mac OS X, and when it does
happen, then you can expect a security update to fix it within a month.
some may wonder "why in the world do I need to enter admin password
to extract files?!".
Again, this is not very likely to happen. Most users will just pass
through, and the few that think about it will probably be technically
inclined enough to know that the reason why it's asking is because
they don't have permission.
And for the small percentage in between, it is possible to customize
the title of the authorization panel, so you can explain it there if
you wish.
