So it seems obvious that PFS is not a binary property; presumanbly the keys are overwritten (seems hard with flash wear leveling) when new messages happen, but there is a perhaps-months "short term key", vs a maybe-years "long term key", and PFS or not becomes blurry. PFS is indeed not a binary property. Aside from confusion arising from the loaded word `perfect' in `perfect forward secrecy', some people argue against using the term at all in favour of `key erasure', and of stating when the relevant keys are erased. _______________________________________________ OTR-dev mailing list OTR-dev@lists.cypherpunks.ca http://lists.cypherpunks.ca/mailman/listinfo/otr-dev
