Support Ed25519 and Ed25519ph #2

Open zamicol opened 1 year ago

zamicol commented 1 year ago

Paul currently supports Ed25519. We're hoping Paul will implement Ed25519ph soon: https://github.com/paulmillr/noble-ed25519/issues/63

The W3C Web Cryptography API recommendation also omits Ed25519, so an external package that implements the Ed25519 primitive is used. The upcoming update FIPS 186-5 specifies Ed25519 support. (https://nvlpubs.nist.gov/nistpubs/FIPS/NIST.FIPS.186-5-draft.pdf, section 7.8) Hopefully this will motivate Javascript to include Ed25519.

Also consider https://stackoverflow.com/questions/75008138/can-subtlecrypto-verify-use-a-digest-instead-of-the-original-message/75008139#75008139

May be reason enough to move to noble-curves fully after release.

We may have multiple "back end" support as well, but SubtleCrypto will be limited in capability.

Also, we'll preserve the current style somewhere so that we have a SubtleCrypto backend that can be used.
