crypto-ISSUE-42: Flatten AlgorithmParameters [design for Web Crypto API]


Raised by: Richard Barnes
On product: design for Web Crypto API

The current spec requires that algorithm parameters be encapsulated in a "params" field within an algorithm identifier.  For example:
OLD: { name: "AES-GCM", params: { iv: [0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0], tlen: 128 } }
NEW: { name: "AES-GCM", iv: [0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0], tlen: 128 }

The only reason this extra complexity would be necessary is if we expected an algorithm to need a parameter called "name".  This does not seem very likely; I see no problem making "name" a reserved word for the purpose of algorithm parameters.

This requires the useless interface "dictionary AlgorithmParameters {};" from which individual algorithms specialize.  Proposed revisions to WebIDL:
-- Remove the AlgorithmParameters definition
-- Remove the "AlgorithmParameters params;" from the Algorithm interface
-- Change all descendants of AlgorithmParameters to instead inherit from Algorithm
