256-bit SSL Encryption
The Advanced Encryption Standard (AES) enables 256-bit encryption, much stronger than 128-bit. If your server operating system and your site visitor’s browser support 256-bit encryption, then all VeriSign SSL Certificates deliver this higher level of protection.
When Browsers Fail to Step Up to Strong Encryption
Even though an SSL Certificate is capable of 128-bit or 256-bit encryption, many millions still use older computer systems that are incapable of strong encryption. These legacy browsers and operating systems fail to step up to strong encryption without an SGC-enabled SSL Certificate:

- [FONT='Helvetica','Arial']Certain Netscape browser versions from 4.07 to 4.72 [/font]
- [FONT='Helvetica','Arial']Many Windows 2000 systems using Internet Explorer [/font]
Internet Explorer browser versions prior to 3.02 and Netscape browser versions prior to 4.02 are not capable of 128-bit encryption with any SSL Certificate.
