Q: What is data encryption?

A: Data encryption “scrambles” information that is sent over the internet, so that only the intended computer can read it. A hacker could still intercept the data, but because of encryption, the information could not be read.

Q: What is 128-bit encryption?

A: SSL comes in two strengths: 128 bit and 40 bit. 128-bit sessions are trillions of times stronger than 40 bit sessions.
