crypto: add TurboSHAKE and KangarooTwelve Web Cryptography algorithms by panva · Pull Request #62183 · nodejs/node · GitHub

Adds RFC 9861 - KangarooTwelve and TurboSHAKE digest algorithm to Web Cryptography API per WICG/webcrypto-modern-algos#41 using adapted OpenSSL's keccak1600 implementation, to be replaced when OpenSSL supports them natively at which point we'd also make them available in stable node:crypto.

Refs: https://www.rfc-editor.org/rfc/rfc9861.html
Refs: https://redirect.github.com/openssl/openssl/issues/30304

The tests for the implementation use both test vectors from the RFC as well as ones generated using PyCryptodome

Can't really review the cryptography here but the code otherwise LGTM

Is using LE part of the algorithm specification? Because Node.js does support BE platforms

It does need to produce the same digests regardless of the platforms's endianness. And it does, i had earlier failures in jenkins on those platforms and handled that.
