Server Gated Cryptography is a way to provide strong encryption in an SSL connection with older Web browsers that support keys only up to 64 bits in length. If the server supports server-gated cryptography (SGC), it returns an SGC digital certificate to the Web browser, known as a "SuperCert," "Global-Server-ID" or "HyperSign." The SGC certificate instructs the Web browser to perform a follow-up handshake to establish keys of 128 bits and higher.
