//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)

Behavior / Spec Changes (will require spec work)

• 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.
