SEF files are cryptographic archives that are used to store files in a secure manner. These files make use of the Twofish encryption algorithm with a 256-bit key. Because of the highly optimized compression and encryption routines used with the Strong Encryption Format, a seamless integration occurs with almost any kind of application. For example, suppose you have several TIFF images of faxes that you wish to remain private. Simply add them to a .sef archive and delete the originals. Any time you wish to work with your faxes, all you have to do is select the file and enter your password.
