node:crypto implementation doesn't support ECDSA secp256k1

[mary-ext]

What version of Bun is running?

1.2.2+c1708ea6a

What platform is your computer?

Linux 6.13.1-2-cachyos x86_64 unknown

What steps can reproduce the bug?

import * as crypt from 'node:crypto';
crypt.generateKeyPair('ec', { namedCurve: 'secp256k1' }, console.log);

What is the expected behavior?

Generates a ECDSA secp256k1 keypair and logs it to console

What do you see instead?

Throws, unsupported by Bun.

Additional information

Used in @atcute/crypto to validate most signatures in AT Protocol, as secp256k1 is more readily available in KMS/HSMs.

Web3/cryptocurrency use cases would also benefit from this addition.

Currently, @atcute/crypto mitigates this lack of support by adding an imports condition for Bun, it would be nice if Bun actually supported this to avoid using the JS-based @noble/secp256k1 library for signing and verification.
