Yeah I&#x27;ve never seen an implementation of OTR that blocked archival—in the journalistic sense, it&#x27;s still <i>on</i> the record so to speak. (That being said, OTR&#x27;s deniable authentication means I can use my plaintext archive to recall the conversation but I can&#x27;t prove to a third party that it&#x27;s from who I say it was—nor would I be able to if I was storing the encrypted conversation.)<p>With the above considered, I&#x27;m curious to hear another argument for OpenPGP over XMPP rather than OTR.<p>(Edit: Should say that there likely are OTR implementations that archive the ciphertext, or don&#x27;t automatically archive at all. However, having used OTR in Jitsi and Adium, both I believe keep regular old plaintext logs.)
