Hi all,

testing the lovely slowness of a pure scrypt implementation in
javascript running into the browser, i was wondering anyone ever tried
to think/design an cryptosystem for key stretching purposes that
leverage only existing webcrypto API
(https://www.chromium.org/blink/webcrypto) with the goal to use let's
say 80% of cpu time on native-crypto-code rather than JS code?

In the browser native crypto code trough WebCrypto API works obviously
much faster than JS crypto code (how much?)!
