Many people want to know the principle of digital authentication. In fact, digital certificates are prompted by public key cryptography. That is to say, a pair of matching keys are used for encryption and decryption. A private key held by a person. Use it for decryption and signature. It has a public key and can be made public. Used to encrypt and verify signatures, there is also a public key, and can be made public. When sending a secret file, the receiver can decrypt it with its own private key, so that the message can safely reach its destination. Even if it is intercepted by others, they cannot see it without a corresponding private key, so this is very secure. these are the principles of digital authentication, which can be understood.

What do you think of the information contained in the https certificate
