// This file contains known answers for ECDSA verify() testing.
// The tests include successful and unsuccessful verifications.
//
// These are the possible fields for each test:
//   "key_format" -- The format of the key data. Can be one of: {"jwk", "spki", "nist".
//   "key" -- The public key data. Either a dictionary JWK, or hex encoded bytes (for SPKI)
//   "msg" -- The hex-encoded message to be verified
//   "sig" -- The hex-encoded ECDSA signature as a concatenation of "r" and "s".
//   "error" -- Optional. If provided, verify() is expected to fail with the indicated error.
//   "verify_result" -- Expected boolean result from verify().
[
