However, we want to be a little more perfect, get an SSL certificate, so I do not have to fear the national treasure to see my mail, but also not afraid of my password leakage, also not afraid of 007. Because no SSL mail is transmitted in clear text, get an SSL encryption bar, and the same thing as the bank site, you can do high-end. First, we'll start with the IMAP certificate, which is a collection, so you can a

Ca is the authority responsible for issuing certificates, certification certificates, and managing issued certificates. It requires policies and specific steps to verify and identify user identities, and sign user certificates to ensure the identity andPublic Key. For example, Alice communicates with Bob. In the event of intercommunication being monitored by hacker C, im
