RBackup allows you to use various Encryption Standards. Depending on the country you are in, some of these standards may not be available to you. They are all available in the United States and Canada.
The old US Federal Standard. "8.2 Compatible" is the legacy RBackup (pre-1995) version, and "8.3 Standard" is the legacy RBackup (pre-1998) version.
A much more secure form of DES
Probably the most secure of all. It uses a key length that is variable from four bits to 448 bits.
The latest US Federal Standard. RBackup supports three levels of AES from 128 bits to 256 bits. 256 bit AES is very secure, but it is also slow.
