Interscope BlackBox makes it easy
               to secure files in Windows. It's a fast,
               effective method of file encryption
               and provides a host of features and
               options. Once the program is
               installed, several new items appear
               on the menu when you right-click on
any file or folder. Simply choose Encrypt and supply a
password to protect your selection. The file is then
transformed, using the DES algorithm with a 56-bit key
(other options are available as downloadable plug-ins),
into a secure file that cannot be read without the password.
To restore the original file, just enter the password. Files
and folders can be grouped together in a "security set" that
allows encrypting or decrypting all the objects in one easy
operation. Targets residing on different drives and folders
can be combined in the same set. BlackBox also allows
you to create self-extracting executable files and to send
encrypted files via email in a single operation. Other
options include file compression, a secure shredder, an
exclusion list, and more.
