you won't be lost if you already know these clients.  Configuration can be

the correspondent is who you think it is.  (3) Deniability: The messages you
send do not have digital signatures that are checkable by a third party.  Anyone
can forge messages after a conversation to make them look like they came from
you.  However, during a conversation, your correspondent is assured the messages
he sees are authentic and unmodified.  (4) Perfect forward secrecy: If you lose
control of your private keys, no previous conversation is compromised.")
