1856679 - support even more derived key algorithms in crypto.subtle.deriveKey

Status: RESOLVED INVALID

(Core :: DOM: Web Crypto, enhancement)

Description

+++ This bug was initially created as a clone of Bug #1851928 +++

crypto.subtle.deriveKey still doesn't support that many derived key algorithms right now. In particular, it doesn't seem to support PBKDF2.

Unless I'm misunderstanding, it seems like Firefox does support PBKDF2. I wrote a test for the mdn-bcd-collector project (https://mdn-bcd-collector.gooborg.com/tests/api/SubtleCrypto/deriveKey/derivedKeyAlgorithm_option_pbkdf2), and it's reporting that support was introduced in Firefox 119. Note that I wrote this test with minimal knowledge of the Web Crpyto API, so please let me know if this test code is incorrect!

Hi, Firefox indeed has started supporting PBKDF2, you can check here: https://wpt.fyi/results/WebCryptoAPI/derive_bits_keys?label=experimental&label=master&aligned. These are the tests each browser passes.

The test seems correct

https://searchfox.org/mozilla-central/source/testing/web-platform/tests/WebCryptoAPI/derive_bits_keys/pbkdf2.js might help to write tests

I guess so!

Thank you! Vinyl has already updated compatibility data for this.
