clientCredentialType certificate Validation mode----chaintrust Authentication mode The Chaintrust authentication mode uses a certificate chain to verify that the X.509 certificate is valid and is issued by a trusted issuer. It specifies that each certificate must exist in a certificate hierarchy that ends with the root certification authority at the top of the certificate chain. It verifies that the X.509

. openssl features both OCSP and CRL functionality, but the introduction of these features is beyond the scope of this article. the current standard for digital certificates is X.509, which is defined in RFC 3280. openssl has a library dedicated to digital certificates. The source code for this library is located in the crypto/x509 and Crypto/x509v3 directories. source code defines several OpenSSL structures related to X.

website's certificate signed by an authority. When a user accesses your website through HTTPS, the browser will verify the certificate.1.3 Download CertificateCertificates are classified into many formats, such as X.509 (. crt file) and PKCS #7 (. p7s file. Different website servers may require certificates in different formats. Most of the time, the certificate is signed by a secondary certificate authority, which also has a root certificate authori

SSL/TLS Protocol version, and the compression algorithm. ServerHello also contains a random number of 4 + 28 bytes, which is generated by the server. Certificate: both the client and the server can send a Certificate message to prove their identity, but the client Certificate is usually not used. Generally, the server receives a Certificate message after ServerHello. The Certificate message contains a Certificate chain, starting from the server Certificate to the Certificate authority (CA) or

operation in the X.509 section. Digital SignatureDigital signature is another application of the public key system. A needs to send A packet to B. First, A uses A specific Hash algorithm to obtain A Hash value of A certain length (such as 128 bits) for the packet to be sent, this Hash value is called a Digital Digest ). The Hash algorithm tries to ensure that the digest generated by different packets is different. That is, if the sent packet is modi
