Encryption is the process of converting plain text into scrambled code to help to safeguard the transmission of confidential data. Most browsers use 40-bit encryption. Encryption at 128-bit strength provides a significantly greater amount of cryptographic protection.
The numbers "128" and "40" refer to the size of the key used to encrypt the message. With hackers gaining increasing computing power, it is necessary to employ larger keys than has been needed in the past. To compare the two, 128-bit encryption is approximately 309,485,009,821,345,068,724,781,056 times stronger than 40-bit encryption.
