下面是Armadillo对Secured Sections的说明：
For a long time, shareware developers have considered it safest to distribute "demo" versions of their programs, and ship separate, "full" versions when customers purchased. When programs were distributed only on disk, by mail, this made sense; there was no point in shipping the full version when someone could "crack" it and steal the program. Now the Internet has changed all that -- customers want to have the full version instantly, and they don't want to spend the time downloading another copy of your program when it's almost the same as the demo version they already have.
With the Secured Sections feature of SoftwarePassport/Armadillo, you can now have the security of a separate demo version, and still provide your customers with instant access to the features of the full version! The Secured Sections are encrypted separately, each with its own unique encryption key. Even if someone manages to strip the SoftwarePassport/Armadillo shell off of the program, your Secured Sections won't be included without a key that permits access to them.
