Secure Sockets Layer (SSL) is a protocol for transmitting private information over the Inter- net. SSL uses two keys to encrypt data: a public key known to everyone and a private or secret key known only to the recipient of the message.
SSL certificates are issued by trusted Certification Authorities (CAs). The CA digitally signs each certificate. Each client contains a list of trusted CAs. When an SSL handshake between a server and your Gateway occurs, the client verifies that the server certificate was issued by a trusted CA. If the CA is not trusted, a warning will appear. Certificates installed in your Gateway and servers to which it connects verify to each other that commu- nications between them are encrypted and private.
Certificates are purchased from an issuing Certificate Authority, usually by your corporate IT department or other service provider, and provided to users for secure communications.
You must obtain a certificate file before you can install it.
