wycheproof2blb: secp256k1 with P1363 format #1092

parsing ecdsa_secp256k1_sha256_p1363_test.json

I guess these are vectors for the IEEE P1363, which unless it also goes by some other name (which I can't verify because I don't have access to the document) we don't support.

From Wikipedia:

The IEEE Standard Association withdrew all of the 1363 standards except 1363.3-2013 on 7 November 2019.

From what I can tell this is some other form of message encoding beyond the existing ones we support.

The legacy IEEE 1363 has a very simple signature format with only r + s, totaling 64 bytes. I’ve searched some P1363 signatures in the test cases, and they are unique, not just copied from other cases.

Aah, never heard it referred to that way. It's what we call just ecdsa::Signature or a "fixed" signature
