@RyanTheOptimist I created this new PR after closing my previous PR, whose branch history was messed up when I tried to fix the missing sign-off issue. Sorry about the confusion.

In the future, please don't create new PRs in cases like that. We can help with the git issues, I think :) But no worries this time.

It should be 31615. Let me fix my comment. Support FIPs crypto from WASM plugin was closed with wasm: register verify_signature as foreign function #32127. It is to add the missing sign feature so that WASM can both sign and verify signatures using FIPS crypto.
