Note: The default port number for HTTP is 80.
Setting the HTTP authentication method:
The HTTP server supports two authentication methods for security and validation of
the username-password – Basic and MD5 digest.
The Basic method utilizes Base64 encoding to encode and deliver the username-
password over the network to the HTTP server for decoding and authentication. This
basic method is supported by all web browsers and offers a minimum level of
security.
Note: The Base64 algorithm is widely-known and susceptible to packet-
sniffer attack for acquisition of the encoded username-password string.
The MD5 digest method provides stronger protection utilizing one-way encoded hash
numbers, never placing the username-password on the network. Instead, the
sending browser creates a challenge code based on the hash algorithm, provided
username-password and unique items such as the device IP address and timestamp,
which is compared against the HTTP server internal user database of valid challenge
codes. The MD5 digest method offers a higher level of security than the Basic
method but at present is not supported by all browsers.
Note: MD5 is known to be fully supported by Internet Explorer 5.0+
