FileVault is the perfect solution for maintaining complete secrecy and security of those important files that you do not wish others to access.
By putting files in the Vault you can completely hide them from anyone who may search your computer when you are not present or over the network. Even system administrators would not be able to access the files in the Vault.
FileVault completely encrypts the contents of your files using differing algorithmns and levels of complexity of encryption for each file.
Vault files can be attached to emails, allowing you to send highly sensitive information over the Internet. You can even send files through filtering firewalls that would normally reject them.
Also included are tools such as "Password Manager" and "Favourites Manager" to maintain encrypted lists of passwords and Internet favourites as well as "Directory Shredder" and "File Shredder" to completely remove all traces of files so that they cannot be recovered even by unerase programs.
