OpenPGP Design Team 2021-08-13 present: dkg stephen justus werner jeffrey paul ## https://gitlab.com/openpgp-wg/rfc4880bis/-/merge_requests/59 We're aiming to break the back of this tricky one today if we can. chunk size seems to be a main bone of contention. - is limit of 56 the right choice? - what does "MUST support" mean? - how does chunk size relate to a streaming interface? - what are the downsides of small chunks? - what are the downsides of large chunks? - how much needs to be stored in memory? - should there be a configurable chunk size? wk: larger buffers make decryption faster because of parallelization justus: really large buffers fail to fit in memory on some machines wk & justus: we cannot presume that the overall size of the packet is known in advance paul: we need to ensure that some implementations do not generate packets that others cannot decrypt. wk: i would be fine with a 4MiB upper limit on chunks (chunk size: 16) paul: what about smartcards? (answer: smartcards are reserved for asymmetric, this is symmetric) wk: i'd be fine with 16 justus: chunk size octet value of 16 is fine with me. sftcd: propose: your implmentation SHOULD be able to emit or receive/process a packet with chunk size 16 werner proposes MUST NOT support a value larger than 16 ACTION: Paul to propose wording for that. ## https://gitlab.com/openpgp-wg/rfc4880bis/-/merge_requests/55 Intended Recipient seems to have consensus of everyone present Editor hit merge during call
