Hi Steve, While authenticating a user to a server, the client has to digitally sign an electronically produced document or piece of data. You will need a client certificate per client. Even if a legitimate user attempts to connect with the right username and password, if that user isn't on a client application loaded with the right client certificate, that user will not be granted access. See here, The ca-certifcates.crt file looks like this. It can also be used to authenticate the client (i.e. SSL stands for Secure Sockets Layer, a security protocol that creates an encrypted link between a web server and a web browser. An Extended Validation Certificate (EV) is a certificate used for HTTPS websites and software that proves the legal entity controlling the website or software package. As we just mentioned, before a secure connection occurs, an SSL/TLS handshake must be performed to handle authentication and to negotiate the protocol version and ciphers that will be used once the connection begins.
