I am not sure what you mean by scramble but if you mean the password
protect feature then I know a little about it. There is a set of
software about which cracks pkzip passwords. Depending on the original
pasword and if you know anything about the password, decides how long
the typical crack takes ( also the speed of your PC ( I only know of a
pc version )) they quote that if the password is 10 characters long
and consists of alpha characters then the crack can take 5 hours.

I tried it on a know 8 character numeric only password and it solved
it in about 5 minutes. (on a pentium 60)
