Can i got private key which derived by Nist256p1 ?

[weixuefeng]

public static DeterministicKey createMasterPrivateKeyNist(byte[] seed) throws HDDerivationException {
        return createMasterPrivateKeyWithKeys(seed, "Nist256p1 seed".getBytes());
    }

i want to create a wallet snap, but my crypto coin used Nist256p1 algorithm. can i got the private key by metamask?

Hey @weixuefeng, thank you for creating this issue! Could you tell us a bit more about your use case? Specifically, why do you need to use the NIST curve? Is it because your protocol requires it?

[weixuefeng]

yes, i want to add "NEW" coin by snap, newton, NEO, ONT used NIST algorithm. could you help me @rekmarks thanks for you reply!

@weixuefeng we are currently blocked on adding this capability due to the lack of a good JavaScript implementation of this curve. We could maybe make do with WebAssembly, but we do not have the capacity to research the matter at this time.

I will keep this issue open since it is a legitimate use case that we want to support.

After doing some digging, the web crypto APIs (window.crypto and window.SubtleCrypto) do actually implement this curve. However, these APIs are low-level and we currently don't have any applied cryptographers available to implement what we need using them. This issue will be in limbo until we do.

Edit: But they don't provide a way to just do multiplication on said curves so we're not actually helped by those either.

ok

I would argue against this. This would make key-tree bigger...the use case is not defined/popular enough
