19:12:18 <ddahl> ... if implementors have a preferred format for additional key types, feedback is very welcome based on the template provided in the spec

19:13:43 <markw> q+
19:13:47 <ddahl> rbarnes: key storage stuff looks good, is there a richer way to label the keys? metadata- > name, etc?
19:14:39 <ddahl> rsleevi: perhaps raise an issue on this - numeric getters and symbolic names are used in localStorage, perhaps we do the same?

19:15:22 <sdurbha> sdurbha has joined #crypto
19:15:36 <ddahl> rbarnes: meta question: can I refer to a key in a persistent way? not clear if these indexes are persistent?
19:15:55 <ddahl> rsleevi: key object has a keyID and this is fully persistent
19:16:30 <vgb> q-
19:16:33 <ddahl> ... symbolic name vs numeric index? does this matter?
19:16:50 <rsleevi> http://www.w3.org/2012/webcrypto/WebCryptoAPI/#key-interface-members
19:17:11 <ddahl> virginie: did you specify the persistence of each key?
19:17:23 <ddahl> rsleevi: still need to do that - add language to clarify
19:17:36 <selfissued> q+
19:17:49 <rsleevi> ACTION: sleevi to add explicit language to clarify that Key object attributes are persistent to keys. the key.id is consistent between browsing contexts
19:17:49 <trackbot> Created ACTION-34 - Add explicit language to clarify that Key object attributes are persistent to keys. the key.id is consistent between browsing contexts [on Ryan Sleevi - due 2012-08-27].
19:17:54 <ddahl> asad: followup: can we indicate a source once we have the key ID?
19:18:21 <ddahl> ... certain operations would be tied to a specific provider
19:18:49 <ddahl> ... is the binding of the key ID to the corresponding source known to the web app?
19:19:16 <ddahl> rsleevi: if an implementation is going to expose providers, it is an implementation detail
19:19:38 <hhalpin> i.e. "custom attribute"
19:20:21 <ddahl> asad: if a user selects a key, it is up to the browser to make sure the operations are executed within the specific source?
19:20:59 <ddahl> rsleevi: yes, but there will be additional discussions on this - [reference to a recently closed issue]
19:21:04 <virginie> q?
19:21:16 <virginie> ack asad
19:21:22 <ddahl> ... this provider issue is in the secondary use cases
19:22:01 <ddahl> markw: where would we put the global Id for a pre-provisioned sym key?
19:22:59 <ddahl> rsleevi: there should be some kind of foreknowledge of the key's meta data that might be stored in localStorage, etc
19:23:08 <ddahl> ... need to raise an issue here
19:23:40 <ddahl> markw: do we need a couple of key IDs to help locate symmetric keys?
19:23:57 <ddahl> ... one global and one in the origin
19:24:52 <ddahl> rsleevi: pre-provisioned attrs should help here  
19:25:45 <rsleevi> ddahl: The (closed) query issue was ACTION-16
19:26:24 <ddahl> markw: most of the attributes are user attributes seem to carry less weight than needed for unique IDs for symmetric keys
19:26:58 <ddahl> (ddahl note: that last bit was hard to scribe)
19:27:17 <ddahl> __markw: was that accurate?
19:27:56 <virginie> q?
19:28:05 <ddahl> rsleevi: there have been a few actions that did not have a wide consensus before closing them
19:28:12 <virginie> ack markw
19:28:30 <ddahl> markw: the GUID for sym keys issue needs more discussion
19:29:11 <hhalpin> either way of dealing with it is actually fine!
19:29:16 <hhalpin> perhaps its more of an open ISSUE
19:29:19 <hhalpin> than an action.
19:29:28 <hhalpin> q?
19:29:31 <hhalpin> q+
19:29:38 <ddahl> virginie:  action 16 was closed, but probably needs postponement instead
19:30:02 <markw> just to be clear, a globally unique identifier for pre-provisioned symmetric keys needs more discussion (it's been suggested that the id field on the key - which is a local identifier - might actually be a GUID)
19:30:14 <ddahl> rsleevi: need to build better consensus on mailing list
19:30:55 <ddahl> selfissued: Need to touch on the relationship between JOSE and W3 web crypto - and how we will use JOSE
19:31:00 <rsleevi> http://www.w3.org/2012/webcrypto/WebCryptoAPI/#use-cases
19:31:25 <ddahl> selfissued: need to have new paragraph on this topic in the spec
19:31:37 <ddahl> virginie: there is something in the draft
19:31:43 <ddahl> ... to that effect
19:32:12 <ddahl> hhalpin: if someone has taken an action and cannot fullfil it - we need to open an issue to help keep track of it
19:32:25 <rsleevi> https://www.w3.org/2012/webcrypto/track/issues/17 / ISSUE-17 is tracking the discussion on attributes
19:32:31 <ddahl> ... or if consuensus cannot be reached
19:33:08 <markw> q+
19:33:17 <ddahl> hhalpin: JOSE was only being referenced in key import/export 
19:33:21 <virginie> ack selfissued
19:33:35 <hhalpin> ack hhalpin
19:34:02 <ddahl> ... we are working on a lower-level API that may not support JOSE directly, however, later a high-level design may better support JOSE directly
19:34:28 <ddahl> selfissued: are you looking to get these new JOSE formats created?
19:34:53 <rsleevi> http://www.w3.org/2012/webcrypto/WebCryptoAPI/#dfn-KeyFormat
19:34:59 <ddahl> hhalpin: does the working group feel that it is something to discuss now 
19:35:03 <ddahl> ...?
19:35:44 <ddahl> selfissued: we need to understand the use cases to make sure it makes sense to support JOSE, some use cases seem to exists just to support JOSE 
19:35:58 <rsleevi> q+ to respond about JOSE
19:36:11 <ddahl> virginie: if we ask JOSE for new formats - private keys, etc, how long will it take to spec?
19:36:42 <ddahl> selfissued: we could have a draft in weeks, making it part of the spec may not happen until IETF ATL in 3 months
19:36:48 <arunranga> I don't think we need a "spec benediction" to start using it.
19:36:50 <hhalpin> I think the use-case is "key import/export" in the secondary features of the charter, http://www.w3.org/2011/11/webcryptography-charter.html.
19:37:14 <hhalpin> We have about a year to reach total stability on our spec, so timing should be relatively easy here
19:37:57 <rsleevi> virginie: There's an ISSUE ;)
19:38:00 <ddahl> markw: unique ID thing is functional and may need a separate issue
19:38:11 <virginie> q?
19:38:12 <ddahl> virginie: let it be so!
19:38:23 <virginie> ack markw
19:38:45 <ddahl> rsleevi: importing og JWK public keys seems like a very useful thing
19:39:20 <ddahl> ... exporting private keys may require some custom operations with polyfills etc in mind
19:39:38 <ddahl> ... exposing this kind of thing for RSA with OEAP will be tricky
19:39:58 <ddahl> ... is there a WEBIDL or JWK format that will allow this
19:40:01 <ddahl> ...?
19:40:42 <ddahl> ... we could create a WebIDL for this operation
19:41:16 <ddahl> selfissued: we should see if we can get IETF to also spec this format 
19:41:38 <rsleevi> ack rsleevi
19:41:38 <Zakim> rsleevi, you wanted to respond about JOSE
19:41:45 <ddahl> rsleevi: the overhead of ASN.1 parser is part of this ongoing issue 
19:41:53 <markw> q+
19:42:11 <ddahl> markw: want to understand how the DH will work?
19:42:22 <rsleevi> http://www.w3.org/2012/webcrypto/WebCryptoAPI/#dh
19:42:36 <ddahl> ... 2 operations, KeyGen and KD - do you use the KD to derive the key?
19:43:38 <ddahl> rsleevi: yes, 3 phases, 1. key gen, export key so we can get either side of key, then KD operation. Phase 2: derive shared secret
19:43:53 <ddahl> ... can an application polyfill? maybe, or we should specify this
19:43:55 <virginie> q+
19:44:07 <virginie> ack markw
19:44:15 <ddahl> markw: we might have a generic key exchange API that makes the algorithm an argument
19:44:29 <ddahl> rsleevi: strong case to keep this operations spearate
19:45:05 <ddahl> rsleevi: fairly common to separate these ops in most crypto APIs
19:45:20 <ddahl> markw: would like to have less specific key exchange API
19:45:29 <ddahl> ... less specific to alg
19:46:06 <ddahl> rsleevi: where do we draw the boundry between low and high level apis 
19:46:30 <ddahl> ... looking for input for the preferred form here
19:46:59 <hhalpin> +1 re slipperly slope, we do have time limits!
19:46:59 <ddahl> virginie: markw: can you provide an example here?
19:47:06 <ddahl> markw: yes
19:48:04 <ddahl> virginie: we have some issues in the draft that do not appear in our issue tracker, should we add them?
19:48:23 <ddahl> rsleevi: yes, the intent was to get more input from WG members
19:48:36 <ddahl> rsleevi: we will convert them all over to real issues
19:49:37 <ddahl> virginie: there is still some heavy debate on the mailing list on various issues
19:50:01 <ddahl> vgb: the import export has made it into the draft, still need more feedback 
19:50:15 <virginie> http://www.w3.org/2012/webcrypto/track/actions/open

19:53:04 <ddahl> wtc: discussed this with ifette, just copied this from the whatwg site
19:54:13 <ddahl> hhalpin: unclear to me about each implementation
19:54:23 <ddahl> wtc: implemented in Chrome and Firefox
19:54:43 <ddahl> hhalpin: will the IE team be interested in implementing it
19:55:34 <ddahl> NOTE: the Firefox implementation is not landed in Firefox nightly yet, waiting on some DOM hackers to look at it. it is implemented in patches:)
19:56:01 <ddahl> vgb: IE team COULD easily implement this, however I do not speak for them:)
19:56:30 <ddahl> hhalpin: changes to the verbiage to make it more clear how this ended up in the spec
19:56:36 <ddahl> wtc: i can clarify this

19:58:15 <ddahl> virginie: need to go find the participants we may not have heard from to get feedback from them
19:58:18 <arunranga> Notes that the synchronous question is an important one which we didn't really discuss.
19:58:40 <hhalpin> thus the editors get a well-deserved vacation!
19:58:47 <ddahl> arunranga: i think the synch version should follow other existing DOM apis that do this
19:58:50 <hhalpin> as people get a week for comments
19:59:07 <ddahl> virginie: try to get as much feedback in by this Friday
19:59:31 <hhalpin> q+

19:59:41 <virginie> ack virginie
20:00:14 <ddahl> rsleevi: some specs are barebones, some are fully spec'd with implementations, we have a number of open issues and actions yet, how far do we wnat to go before we feel like we have a publishable spec?
20:00:30 <ddahl> virginie: we can have many open issue before we publish FPWD
20:01:14 <hhalpin> ack hhalpin
20:02:05 <ddahl> hhalpin: some APIs just document what browsers already do, the nature of this API does want each issue to be well-documented
20:02:23 <ddahl> ... current draft is in good shape
20:02:55 <ddahl> markw: before FPWD we need each functional piece documented in the spec or in an open issue
20:03:20 <ddahl> markw: the identity piece is not well defined
20:03:21 <hhalpin> q+
20:03:34 <hhalpin> ack hhalpin
20:03:41 <ddahl> virginie: propose comments until next monday instead
20:04:26 <ddahl> rsleevi: comments may just be "here is an issue..."
20:04:29 <hhalpin> please send *exact* text if possible to the editors on the mailing list!
