How SSL Works

When an Internet user visits a secure web site, an SSL certificate provides identification information about the web server and establishes an encrypted connection. This process happens in a fraction of a second. What Happens between the Web Browser and Server

• A browser attempts to connect to a web site secured with SSL.
• The browser requests that the web server identify itself.
• The server sends the browser a copy of its SSL certificate.
• The browser checks whether it trusts the SSL certificate. If so, it sends a message to the server.
• The server sends back a digitally signed acknowledgement to start an SSL encrypted session.
• Encrypted data is shared between the browser and the server.



Nexcheck uses SSL with strong 128 bit encryption. A strong encryption at 128 bit can calculate 288 times as many combinations as 40-bit encryption. That's over a trillion times a trillion times stronger. At current computing speeds, a hacker with the time, tools, and motivation to attack using brute force would require a trillion years to break into a session protected by an SGC-enabled certificate.
