A Pidgin plugin for off-the-record conversations
"Off-the-Record Messaging plugin" (or pidgin-otr) is a Pidgin plugin for secure messaging using a protocol known as OTR. Like similar protocols, OTR allows you to hold secure (encrypted and authenticated) conversations. In addition, messages themselves are not signed (that is, they are off-the-record) and remain secure even if your private key is compromised (previous communication streams cannot be decrypted). These features are useful, for example, for journalists. Note, though, that these are technical restrictions not legal ones (a court may consider other evidence).
This plugin offers various methods of initial authentication (challenge/response, shared secret), autogenerates keys, and retains keys so that you can continue conversations with people you have previously authenticated. It does not interfere with unencrypted conversations, although you can prompt the other user to install pidgin-otr (or another OTR client) themselves.
