XRamp Technologies claims to be the first certificate authority to offer 256-bit SSL encryption certificates. The new certificates, which cost $128US for one year, are based on AES-256 encryption.
Support for 256-bit SSL encryption isn't exactly wide spread. Microsoft has not implemented the encryption standard in Internet Information Server (IIS) and Internet Explorer (IE) yet but some Linux-based Web servers such as Apache already offer such support, as does the popular multi-platform Firefox Web browser.
A spokesperson for XRamp said that, "businesses and organizations who currently have a SSL certificate from another provider and wish to switch to XRamp's 256-bit certificate can do so and all remaining time they have left on their existing certificate (up to a full year) will be added to their new 256-bit SSL certificate from XRamp."
