is it possible to crack HASP protected program without the dongle?

[jonwil]

Firstly, looking at the exe in hex editor shows that its probobly encrypted or compressed or both (I dont see strings I know should be there, like filenames for data files)

Secondly, it appears to use nasty code that jumps everywhere, unpacks more code and jumps to more places.

And thirdly, I dont have the origonal dongle and the person who gave me the exe file isnt around anymore and he probobly dosent have it anyway.

If it is encrypted, would it be possible to brute-force the key? (i.e. try every possible key untill you find the one that works) How large is the key (which I assume is on the dongle) for this stuff?
