Although we must voice some minor complaints, this simple-to-use encryption utility hits most of the right notes. Strangely enough, when you install PrivateFiles, you'll see a desktop shortcut for its file shredder, but not one for the actual encryption tool. The program's main window couldn't be more straightforward; you simply browse your machine for files, enter a password, and hit the Encrypt button. The utility makes quick work of securing smaller files, though in some tests, it froze when we tried to lock a large, 1GB document. After PrivateFiles encrypts your data, it automatically gives you an option for attaching it to an e-mail. We're glad the application can create self-decrypting executable files, but neither the encryptor nor the file shredder lets you choose from multiple secure algorithms, restricting you to AES. Therefore, PrivateFiles makes a suitable choice for most home users, but those who work professionally with very sensitive documents may want a more versatile solution.
PrivateFile is an easy-to-use file-and-e-mail-encryption application based on the AES standard. Encrypt your confidential e-mail attachments to protect them from prying eyes as they travel across the Internet. Features include a self-decrypting option so recipients do not have to have a copy of PrivateFile to decrypt attachments. Use the secure KeyStore to hold your frequently used encryption keys. Version 5.5 improved Vista support.
