But potentially an attack on 1024 bit DH or AES-CTR?
OTR uses 1536-bit DH, not 1024-bit DH. It's possible the transcript on the second page of that PDF shows protocol messages (OTR Query, key exchange, etc.) messages. But I don't have a similar explanation for the ones after the undecryptable OTR messages on the first page. - Ian _______________________________________________ OTR-dev mailing list OTR-dev@lists.cypherpunks.ca http://lists.cypherpunks.ca/mailman/listinfo/otr-dev
