can be used on the Internet to identify each other. A digital certificate is a file that is digitally signed by the Certificate Authority center that contains public key owner information and a public key. The simplest certificate contains a public key, a name, and a digital signature for the Certificate Authority Center. Another important feature of digital certificates is timeliness: Valid only for a specific period of time. The public key (public key) in the digita

acts like a driver's license or an identity card in everyday life. It is issued by an authority-CA agency , also known as the Certificate Authority (Certificate authority), which can be used on the Internet to identify each other's identities.A digital certificate is a file that is digitally signed by the Certificate Authority center that contains public key owner information and a public key.

We generally use AES 256 to encrypt the content, here the AES Key management there are two ways, one is to use a fixed key in the client, in order to increase the difficulty of the crack, we can do the key itself multiple encryption processing, use and then decrypt the memory in the real key. The second is that each session uses a different key, similar to the principle of Forward secrecy, even if the traffic is recorded, in the future by brute force, it can greatly increase the time cost of the

although the speed is slow, but the user almost feel, and there are many optimizations can improve speed. With HTTPS does not fully guarantee the site security, security is a multi-factor, multi-link, even if there is https, a ' short board ' can be a site, and HTTPS itself is not safe, such as the famous heart bleeding loopholes. HTTPS also does not absolutely prevent MITM, such as forgery certificate, export plaintext password and so on.

, the request or response is in transit,Attacks by attackers that intercept and tamper with content are called man-in-the-middle attacks (Man-in-the-middle attack,mitm).HTTP itself has a method to prevent tampering, commonly known as MD5 and SHA-1, and a method for verifying the file's digital signature.However, it is not possible to make sure that the results are correct by using these methods, and it is very difficult to ensure integrity by HTTP onl

this handshake is directly tcp,tls,http Triad, which is also the basic principle of Quic 0-rtt.Troubleshooting: Unable to verify the first certificateThe front #8 #5 when I was dealing with a network error, only to know some solutions, but also suspected that the problem is not HTTPS, but can not be verified. Later, after learning the knowledge of HTTPS systematically, it is very simple to explain this phenomenon from this knowledge.Refer to the above TLS handshake, the service side put its own

the key negotiated. However, the DH algorithm itself has drawbacks-it does not support authentication. In other words: Although it can fight "peeping", but cannot resist "tamper", naturally also cannot fight "middleman Xxx/mitm". In order to avoid encountering MITMXXX,DH need to cooperate with other signature algorithms (such as RSA, DSA, ECDSA)--rely on the signature algorithm to help authentication. When DH is used in conjunction with RSA, it

on the client. Now you must use the REQUIRE X509 to require a valid certificate. If this CA is used not only on MySQL server, it will not work, because other people may also get a valid certificate, You can use REQUIRE SUBJECT '/cn=myclient.example.com ' to limit the use of certificates. The certificate you set up here is issued by your CA, and you can have a lot of control over the certificate you issued, and the result is that the certificate you issued is trusted. Configuring 3:server/cl

requires the seller to provide the relevant services (firewalls, intrusion detection systems, etc.) to enhance their security. Security audits of third-party SaaS application deployments are also necessary to better identify any security issues or threats to ensure the security of your enterprise data. 4, network security. In the SaaS deployment model, traffic between the Enterprise and the SaaS provider must be protected during transmission to prevent the leakage of sensitive information. SaaS
