Bryon Support?

[timmolter]

Hi, great looking library!

Are there plans to support Bryon master seed generation?

• https://github.com/cardano-foundation/CIPs/blob/master/CIP-0003/Byron.md

And the same question for Ledger: https://github.com/cardano-foundation/CIPs/blob/master/CIP-0003/Ledger_BitBox02.md

I created a dedicated source file, master_key_generation.dart, but the crypto package I'm working with, pinenacl, has a limited set of hash functions, digests.dart. I couldn't figure out how to do the

  function hashRepeatedly(key, i) {
    (iL, iR) = HMAC
        ( hash=SHA512
        , key=key
        , message="Root Seed Chain " + UTF8NFKD(i)
        );

equivalent.

Let's leave this issue open until somebody figures this out.

This package would probably work for the HMAC step: https://pub.dev/packages/crypto.
