The encryption process use by digital certificate is known as Public Key Infrastructure (PKI). This involves the use of two keys, a public key and a private key. The public key is use to encrypt the data, while the private key is use to decrypt it. This means that any data transmit between the web server and the web browser is encrypt and can only be decrypt by the intend recipient.
