Ethereum Signing/Keccac 256/ECDSA support

Grafana k6 Extensions

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:

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

Hi @rahulksnv,

ECDSA should be now supported, it has been introduced by k6 v0.51.0. Where did you get this information? So we can update the documentation.

Unfortunately, as far as Iā€™m aware, Keccak is not officially supported yet by JavaScript WebCrypto API which is the reference tracked by k6ā€™s module.
