Encryption

Layer 6 is also responsible for data encryption. Data encryption protects information during its transmission. Financial transactions (e.g. credit card information) use encryption to protect sensitive information as it traverses the Internet. An encryption key is used to encrypt the data at its source and then to decrypt the data at its destination.
