//components/webcrypto plan

This document outlines the plan for the code living in this directory. The current code is more or less in maintenance mode.

Code Changes

Investigate whether CryptoThreadPool is necessary, whether it is necessary for all operations, and whether it can be use some existing more generic thread pool rather than requiring a dedicated worker thread (https://crbug.com/623700)
Fix the semantic mismatches in JWK importing with usage masks (https://crbug.com/1136147)
Make AES key scheduling more efficient by not recomputing keys all the time (https://crbug.com/1049916)
Move the entire component into blink and get rid of a bunch of abstraction layers (https://crbug.com/614385)
Remove the unnecessary “threadsafety caches” in WebCrypto keys (https://crbug.com/1180244)

Either finish the X25519 / ed25519 implementation (which will probably require standardizing it) or remove it (https://crbug.com/1032821)
Make most of the operations synchronous instead of asynchronous - they are fundamentally fast and do not need to be farmed out to worker threads, except for maybe key generation.
