Allows you to encrypt your important data using a key file instead of a password. The key file holds the information to encrypt or decrypt your files, so there is no password to remember. Only the person who has the key file and Mastercrypt can decrypt your files. You can encrypt or decrypt a list of files and delete them after the process, as well as save that list in a text file. In addition, the program includes command-line options for all its features (to use it in a BAT file for example), and lets you compress your files before you encrypt them. You can password protect Mastercrypt so that only you can use it.
