What is a public key certificate

A public key certificate is a HTTPS certificate, or certificate for short, which is a digitally signed certificate. It proves whether the public key of the server is sent by the server, and prevents the third party from intercepting when the server communicates with the client. When the client receives the public key of the server with a digital certificate, it means that the person who sends the data is really the server, not impersonated. What is a public key certificate? the certificate includes: the digital signature of the issuer, the issuer identifier information, the validity period of the certificate, the public key value of the subject, the identifier information of the subject, etc. At this point, you know what it is about obtaining a public key for a HTTPS certificate, which is relatively secure with a digitally signed certificate.

II. Application for HTTPS Certificate

HTTPS certificate is like a person's ID card, we all know that the ID card we use can not be tampered with, even someone's forgery can be identified, and it is recognized and issued by authoritative public security organs. A person's ID card is full of personal details, which is the most effective proof of a person's identity. The same is true of the HTTPS certificate, which contains the details of the applicant, and its issuer is also an authoritative organization and is granted credit. There is a certain process for HTTPS certificate application. When applying, you should know which certificate you apply for. There are many departments in CA. Different departments issue different certificates, and the price of different certificates is also different. So before you apply for a HTTPS certificate, you should determine your needs and decide what kind of certificate you want to apply for according to your own situation. The real certificate is very expensive and is generally used on larger corporate websites.

Although the HTTPS certificate is more secure to obtain the public key, due to the price problem, many personal websites do not use the real HTTPS certificate, but use the self-signed certificate created by themselves. the self-created certificate can also be used and has a certain effect, but it is not recognized by CA institutions, but it is good value for money.
