To check that all newtypes (SecretKeys, Poly1305, etc.) implement the correct traits, new testing functions are needed.

For example fn test_traits_secret_key<Secret: Debug + Drop + PartialEq>() {} could be used to check that a secret key implements the needed traits in a test like so:

fn test_traits_secret_key<Secret: Debug + Drop + PartialEq>() {}

#[test]
fn test_implemen

The gem is presently not packaged in such a way it will build on non-x86 architectures.

It shouldn't be too hard as it already packages the portable ref10 implementation, but some work will be required in e.g. extconf.rb

While there are a number of build tags to try to force the no assembly and 32-bit backends to be build and exercised this really should build and test with an actual 32-bit toolchain/system so that stupid errors can be caught.

As we don't care about performance, QEMU or something should be sufficient here.

publicKeyJwkFromPublicKeyBase58 method is present for Ed25519 suite but is missing for secp256k1 .

Suggested method:

const publicKeyJwkFromPublicKeyBase58 = value => {
  const publicKeyHex = publicKeyUInt8ArrayFromPublicKeyBase58(value).toString('hex')
  const publicKeyJwk = publicKeyJwkFromPublicKeyHex(publicKeyHex)

  return publicKeyJwk
}
