Add UMAs about the usage of the WebCrypto deriveBits operation We are discussing [1] a backwards-incompatible change in the Web Cryptography API spec to modify the length parameter of the deriveBits operation. This CL adds counters to measure the usage of this operation with 2 different values. The first one is to detect '0', which cam be passed explicitly or coercer due to 'undefined' or 'null' values. The other counter wants to evalue values that may cause the derived bits to be truncated; this affects the ECDH and X2519 algorithms.

Chromium is an open-source browser project that aims to build a safer, faster, and more stable way for all users to experience the web.
The project's web site is https://www.chromium.org.
To check out the source code locally, don't use git clone
! Instead, follow the instructions on how to get the code.
Documentation in the source is rooted in docs/README.md.
Learn how to Get Around the Chromium Source Code Directory Structure .
For historical reasons, there are some small top level directories. Now the guidance is that new top level directories are for product (e.g. Chrome, Android WebView, Ash). Even if these products have multiple executables, the code should be in subdirectories of the product.
