–The length of the public key (RSA key) that is used for encryption when setting up an SSL session is 1024 bits, providing more complex encryption and consequently a higher level of security than the public key used in Method 1. (This longer encryption key is also used in Method 3.)

–The server certificate that you upload to the Management Card enables SSL to authenticate that data are being received from and sent to the correct Management Card. This provides an extra level of security beyond the encryption of the user name, password, and transmitted data.

–The root certificate that you install to the browser enables the browser to authenticate the Management Card’s server certificate to provide additional protection from unauthorized access.

•Disadvantage:

Because the certificates do not have the digital signature of a commercial Certificate Authority, you must load a root certificate individually into the certificate store (cache) of each user’s browser. (Browser manufacturers already provide root certificates for commercial Certificate Authorities in the certificate store within the browser. See Method 3.)
