使用WebCrypto验证ECDSA签名失败

async function verifySignature(publicKey, signature, data) {
  const crypto = window.crypto.subtle;

  try {
    const verified = await crypto.verify(
      {
        name: "ECDSA",
        hash: { name: "SHA-256" },
      },
      publicKey,
      signature,
      new TextEncoder().encode(data)
    );

    return verified;
  } catch (error) {
    console.error("Signature verification failed:", error);
    return false;
  }
}

// 示例用法
(async () => {
  const publicKey = await crypto.subtle.importKey(
    "spki",
    new Uint8Array([...]), // 公钥数据
    {
      name: "ECDSA",
      namedCurve: "P-256",
    },
    false,
    ["verify"]
  );

  const signature = new Uint8Array([...]); // 签名数据
  const data = "Hello, World!"; // 待验证的数据

  const result = await verifySignature(publicKey, signature, data);
  console.log("Signature verified:", result);
})();
