Why is encryption strength important?

Encryption strength is determined by the browser, the web user’s operating system and the SSL Certificate. The encryption strength of the secure connection may be 40, 56, 128, or 256 bit. High-level encryption, at 128 to 256 bit means that the data cryptographically encoded during an SSL session is at the strongest level available and almost impossible to break. Compared to a 40-bit encrypted SSL Certificate, 128-bit encryption is more than 300 septillion (300,000,000,000,000,000,000,000,000) times stronger.
