This has been constantly mentioned in the past. While submissions from non-members are valuable and considered, it may be more fruitful to consider formally joining the WG (including IPR policy agreements) and making a formal member submission (eg: a spec) that provides a practical API, rather than describing the high-level objectives without any implementation guidance or concerns. However, as has been mentioned several times, the focus and priority of this WG has been to resolve the low-level API issues. For practical comments, I feel that the current doc is full of hand-wavey ideas that provide no guidance or actual APIs that show how many of these concepts are to work or be used. I also think that, absent formal membership, the IPR policies likely prevent this being something that the WG could adopt. > > I have updated the document with a privacy consideration section. > > The scheme offers no privacy silver bullet but maybe a "workable solution". > > A generic Web Crypto issue seems to be that either you end-up with a standardized "key-picker" (probably pretty difficult to define) which would mark the selected key as usable by the application to use with the Web Crypto API, or you leave this responsibility to the [presumably well-written] application. The described solution bets on the latter because this is much more flexible and may even turn out to be a prerequisite for market acceptance. However, this introduces a potential privacy risk, since there's no platform-provided protection against key "misuse". > > BTW, I have recently been experimenting with the extension-scheme used by for example Google to access the Android Play-store which is based on stand-alone handlers for unique protocols like "market://". This is a strong challenger to Web Crypto solutions for pre-provisioned keys. This scheme also fits quite nicely with the described solution. > > -- Anders > >
