. This leads to the question of who a public key belongs to. It must be authenticated by an authority trusted by the public. Otherwise, a fatal security vulnerability will occur in the entire business system. At present, a common solution in the world is to establish a certificate and visa authority (CA), where ca uniformly manages the public key and distributes the public key in the form of a public key ce

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

In HTTPS learning note two, the concept of digital certificates has been clarified, composed and how the client validates the server-side certificate during the HTTPS connection process.

client, or by a CA that the client trusts. The client verifies the certificate and verifies that the server's identity is correct. After the verification is complete, the encryption is used after negotiation, and the client tells the server that all data swaps are encrypted from now on and sends an encrypted authentication "message" to the server. Server authentication is sent by the client, and "message" can be decrypted. The serve
