SSL is widely used to secure the data transmission between the Web browser and servers. It is mainly applied through ecommerce and online banking. SSL mainly provides the following services: 1. Authenticate the users and the servers based on the certificates to ensure the data are transmitted to the correct users and servers; 2. Encrypt the data transmission to prevent the data being intercepted; 3. Maintain the integrality of the data to prevent the data being altered in the transmission. Adopting asymmetrical encryption technology, SSL uses key pair to encrypt/decrypt information. A key pair refers to a public key (contained in the certificate) and its corresponding private key.
