The concept of SSL digital certificate may seem simple, but is it only the kind of protection on the surface? In fact, it is not. When a website deploys a SSL digital certificate, it is equivalent to assigning two keys to the URL, one as the public key and the other as the private key. The public key can add a lock to the information when it is stored in the web address to prevent it from being stolen by others, and if you want to obtain the information, the lock can only be opened by the corresponding private key. Under the combined action of these two locks, our information privacy on the web site has been well protected.
