ocsp

The online revocation service is a new component introduced in Windows Server 2008. Is the Microsoft deployment of the OCSP protocol. This feature, coupled with the new OCSP answering service, is a big boost compared to CRL based revocation. The client's OCSP client has been redesigned for the schema, plus an OCSP resp

Session ticket need to maintain a global key to decrypt, need to consider key security and deployment efficiency. Generally speaking, the function of session ticket is obviously superior to session cache. The client implementation is preferred to support session ticket. 2.4 OCSP sta

process 302 redirection. 3. Three-way handshake to re-establish the TCP connection. The time consumed is one RTT. A) After 302 is redirected to the HTTPS server, because the port is different from the server, you need to complete three new handshakes to establish a TCP connection. 4. TLS full handshake Phase 1. At least one RTT is consumed. A) At this stage, the cipher suite negotiation and certificate identity authentication are completed. B) the server and the browser negotiate the same key e

Time consuming at least one RTT.A) This phase is primarily the completion of cryptographic suite negotiation and certification of authentication.b) The server and browser will negotiate the same key exchange algorithm, symmetric encryption algorithm, content consistency check algorithm, certificate signature algorithm, Elliptic curve (non-ECC algorithm does not need) and so on.c) The validity of the certificate required by the browser after obtaining it, such as

Time consuming a RTT.A) 302 after jumping to the HTTPS server, due to different ports and servers, a three-time handshake is required to establish a TCP connection.4. TLS full handshake phase one.

Have you already used tree-shaking and code-splitting two tools in react and angular? Have you used compression techniques such as Brotli, Zofli, and Hpack, or the OCSP Protocol (online Certificate status protocol)? Do you know about resource reminders, client reminders, and CSS contain

the user with a certificate verification service, the PKI system.The basic principle is that the CA is responsible for auditing the information, then "signing" the key information with the private key, exposing the corresponding public key, and the client can use the public key to verify the signature. CAS can also revoke certificates that have already been issued, including two types of CRL files and OCSP in the basic way. The specific process for C

Ra accepts and reviews users' certificate applications, such as certificate cancellation and restoration applications; KMC is responsible for the generation, storage, management, backup, and recovery of encryption keys. The certificate publishing and query system generally uses the OCSP (Online Certificate Status Protocol, Online Certificate Status Protocol) Protocol to query User Certificates, the backup and recovery system is responsible for backi
