Implement `PBKDF2` across supported API

[olegbespalov]

What?

Web Crypto API defines PBKDF2 algorithm identifier (https://www.w3.org/TR/WebCryptoAPI/#pbkdf2) for operations like:

• Derive Bits (our implementation has it)
• Derive Key (in-progress Derive Key xk6-webcrypto#83)
• Import key (our implementation has it)

Golang has an implementation in x/crypto https://pkg.go.dev/golang.org/x/crypto/pbkdf2.

We have to implement this support.

As part of the issue, probably following web platform tests (see README) should be enabled:

• WebCryptoAPI/derive_bits_keys/pbkdf2_vectors.js
• WebCryptoAPI/derive_bits_keys/pbkdf2.js
• and others test cases that could be useful for testing PBKDF2

Why?

Having support of the PBKDF2 makes our implementation compliant with web crypto API

Hi @olegbespalov , Is this something which i could possibly work on? I have a bit of development experience in go, I want to give it a try.

Thanks.

Hey @SRasaikar ! I'm no longer a k6 maintainer, but sure — it looks quite isolated and seems like a good one to start with.

There’s already an open PR (in the former xk6-webcrypto extension) that tried to address it, but it didn’t get merged. Sharing it not to suggest you should continue that work, but just FYI that it exists.

Happy contributing, and thanks!

Thanks @olegbespalov .

Hey yall,

@SRasaikar are you still working on this? I tried implementing this and think I got a working implementation ready!

Also @olegbespalov do you who I could reach out to get push access to a feature branch? currently blocked by that

Thanks!

Hi @rahulmedicharla, can not tell you if @SRasaikar is still working on this, but I can with the other part.

In general you won't get a push access to a repository until you are a maintainer. You should fork the repo and push to the fork and make a PR request from there.
Some docs and a fireship video

Hey @mstoykov sounds good, thank you!

Opening a PR for it now
