Ethereum Signing/Keccac 256/ECDSA support

Hi,

I am trying to implement something like this:

1. The k6 load test script takes as input the following: Ethereum wallet details <key pair, wallet address>
2. Signs a random message M with the private key, and sends out <M, signature, public key, wallet address> to another server

I looked at the various related possibilities:

• k6 JavaScript API
• webcrypto
• And also the xk6-ethereum, xk6-crypto extensions

But could not find anything that does quite what I need. The crypto APIs for example have HMAC based signing, but not ECDSA or Keccac256 based signing

Please let me know.
Thanks
