Off-the-Record Messaging

Privacy Levels

A conversation can have one of four privacy levels:

Alice and Bob are communicating with no cryptographic protection; they are not using OTR at all. Mallory, who is watching the network, can read everything they are saying to each other.
Not private
Alice and Bob are using OTR, and they have authenticated each other. They are assured that they are actually talking to each other, and not to an imposter. They are also confident that no one watching the network can read their messages.

Alice and Bob are using OTR, but they have not authenticated each other, which means they do not know for certain who they are talking to. It is possible that Mallory is impersonating one of them, or intercepting their conversation and reading everything they say to each other.

Alice was talking to Bob using OTR, but Bob has decided to stop using it. In this level, Alice is prevented from accidentally sending a private message without protection, by preventing her from sending any further messages to Bob at all. She must explicitly either end her side of the private conversation, or else start a new one.


  1. thanks emblack.

    looks good, is it easy to use?

  2. yes, it is indeed very easy to use, but you have to download pidgin at : http://www.pidgin.im/
    it supports many differnt im software, such as AIM/MSN messenger/Yahoo IM/ICQ…
    after you install that, you go to : http://www.cypherpunks.ca/otr/ download the ORT plug in for Pidgin, if you are using lunix, it probably will be more difficult, if so, you can email me, so i find somebody to help you figure this out.

    its good to talk on encryption, the security culture!

  3. i agree its good to talk on encryption. it gives us more convenience.
    i’ll try it out and let u know what i think about it. thanks!
