Description:

this page claims
'If you are at all concerned about password "sniffing" attacks then md5 is
preferred. '
but how does this really help? If an md5 hash is enough to get access, then
sniffing an md5has is actually the same as sniffing the password?'

There is random salt added to the network md5 hash. Please read the
docs on this.
