Digital certificate refers to a kind of digital authentication that identifies the identity information of all parties in Internet communication, and people can use it to identify each other's identity on the Internet. Therefore, digital certificates are also called digital identity certificates. Digital certificate ensures the integrity and security of information and data by encrypting or decrypting the information and data of network users in computer network communication.

The basic architecture of digital certificate is public key PKI, which uses a pair of keys to encrypt and decrypt. The key includes a private key and a public key. The private key is mainly used for signing and decrypting. It is customized by the user and only known by the user. The public key is used for signature verification and encryption and can be shared by multiple users.

Before sending information, the sender needs to contact the receiver and encrypt the information with the public key. The information is always in the ciphertext state during transmission, including the encrypted information received by the receiver, which ensures the uniqueness of information transmission. If the information is stolen or intercepted, only the private key of the receiver can be used to interpret the data, but the data cannot be changed.
