If the browser supports 128-bit encryption, then a 128-bit session will be established if your web server supports 128 bit sessions. The same is true for 256-bit encryption.
The public key that is created on your server must be a minimum of 2048 bits, depending on your server software.
LAWtrust SSL Certificates are automatically and transparently trusted by most browsers. This trust is established because Entrust’s Root Certificate has been embedded in most major browsers.
