+It has a very limited utility (if any) for real applications, as it lacks the following protocol features:
 
 - cryptographic signature verification, instead it simply compares provided "signature" with stored "public key", effectively treating them as plain text passwords.
 - there is no transport encryption
 
-These limitations make it easy to experiment with the protocol logic via telnet.
