Without data encryption, secure commerce over the Internet would be impossible. When information is sent over the Internet, it travels on public lines, potentially accessible to anyone. This means that the private and sensitive information can be intercepted and used by any hacker who knows how to do so.
Data encryption "scrambles" the information sent over the Internet so that only the computer it is intended for can read it. The hacker can still intercept your data file, but, because of the encryption, the information it contains cannot be read or used by him/her.
128-bit encryption provides a significantly greater amount of cryptographic protection than 40-bit encryption. Roughly speaking, 128-bit encryption is 309,485,009,821,345,068,724,781,056 times stronger than 40-bit encryption. 40-bit encryption is not considered "strong" security in the cryptographic community.
Accordingly, 128-bit data encryption has become the standard for securing financial information on the Internet. If we want to do business on the Internet, we and our Business Partners NEED 128-bit encryption.
