subtle.sign(algorithm, key, data)
-
algorithm：<AlgorithmIdentifier> | <RsaPssParams> | <EcdsaParams> | <Ed448Params> -
key：<CryptoKey> -
data：<ArrayBuffer> | <TypedArray> | <DataView> | <Buffer> -
返回：<Promise> 包含 <ArrayBuffer>
¥Returns: <Promise> containing <ArrayBuffer>
使用 algorithm 给出的方法和参数以及 key 提供的密钥材料，subtle.sign() 尝试生成 data 的加密签名。如果成功，返回的 promise 将使用包含生成的签名的 <ArrayBuffer> 进行解析。
¥Using the method and parameters given by algorithm and the keying material
provided by key, subtle.sign() attempts to generate a cryptographic
signature of data. If successful, the returned promise is resolved with
an <ArrayBuffer> containing the generated signature.
