Password Generator Protocol
The uniqueness of the generated words is highly dependent on the
randomness of the initial seed value used. The availability of a
single system-wide seed, updated after each access is highly
desireable. Seeds based on a time-of-day clock are unacceptable.
Seed values should be stored as values in excess of 32 bits for
best performance.
TCP Based PWDGEN Service
One PWDGEN service is defined as a connection based application on
TCP. A server listens for TCP connections on TCP port 129. Once
a connection is established, the six CRLF-delimited words are
generated and sent to the caller, and the connection is closed by
the server. No dialog is used or required.
UDP Based PWDGEN Service
Another possible PWDGEN service is defined as a datagram based
application on UDP. A server listens for UDP datagrams on UDP
port 129. When a datagram is received, the six CRLF-delimited
words are sent back in an answering datagram.
