Off-The-Record Email

2010-03-11 Thread erythrocyte
I'm a user of Pidgin with the off-the-record plugin:

Is there a way to be able to have off-the-record email conversations
with GPG technology? It would definitely be a terrific thing. Email is
traditionally supposed to mirror paper mail and paper mail is usually
not thought of as being off-the-record, so I guess that's probably why
no one really thinks about it.

But if the technology exists, it would be fantastic to have OTR email
conversations every now and then.

I came across some interesting articles and papers worth checking
out:

but nothing out there for users to be able to use.

I was pondering with the idea to use the WoT or an existsing OpenPGP key
for fingerprint checking.  No concrete design, though.

I'd personally prefer having a real OpenPGP plugin for gpg,...
Wouldn't that be the real solution?


Cheers,
Chris.

Not really.  OTR uses DHKEA for symmetric key negotiation.  This is an 
interactive protocol: you send some information, the other person sends some 
information back, back-and-forth a few times until a symmetric key emerges from 
the mathemagic.

Email is not an interactive protocol.  You could probably invent a way to do 
OTR via email, but it would probably be a horrible kludge.
