Absolutely. When an SSL handshake occurs between a client and server, a level of encryption is determined by the browser, the client computer operating system, and in certain situations the SSL Certificate. Low-level encryption, 40- or 56-bits, is acceptable for sites with low-value information. However, a hacker with the time, tools, and motivation can crack the code in a matter of minutes. High-level encryption, at 128-bits, can calculate 288 times as many combinations as 40-bit encryption. That?s over a trillion times a trillion times stronger. That same hacker with the same tools would require a trillion years to break into a session protected by an SGC-enabled certificate.
