It also establishes an encrypted communication channel and switches the protocol to HTTPS once installed on the server. What is SSL certificate Server certificates are the most popular type of X.509 certificate. SSL/TLS …
certificate chain is an ordered list of certificates, containing an SSL/TLS Certificate and Certificate Authority (CA) Certificates, that enable the receiver to verify that the sender and all CA’s are trustworthy. The chain or path begins with the SSL/TLS certificate, and each certificate in the chain is signed by the entity identified by the next …
