Drop Secure Pro starts by dividing up the file into small chunks. By default, those chunks are 256 bytes long. Each chunk is encrypted with a separate cipher, using a separate password that is derived from a hash of information provided by the user, from the archive, and from the data being encrypted. This password is used only once for that one chunk of data, and then discarded.
Easy to use. Drop Secure supports a drag and drop model to encrypting files and directories.
Strong, unique handling of encryption. Each file is divided into tiny peices, and can be encrypted with a separate cipher and password (Passwords are created computational using a single password provided by the user).
Compresses for smaller file sizes.
Cross Platform - runs on Linux, Mac OS X, Windows

The archive manager allows files to be added to or removed from already created archives.
The archive manager supports "Refreshing" an archive - if a newer version of a file within the archive exists on the file system, Drop Secure will add it to the archive, and remove the old one.
