subtle.encrypt(algorithm, key, data)

新增于: v15.0.0

algorithm: <RsaOaepParams> | <AesCtrParams> | <AesCbcParams> | <AesGcmParams>
key: <CryptoKey>
data: <ArrayBuffer> | <TypedArray> | <DataView> | <Buffer>
返回：<Promise> 以 <ArrayBuffer> 完成

使用由 algorithm 指定的方法和参数，以及由 key 提供的密钥材料，subtle.encrypt() 尝试对 data 进行加密。如果成功，返回的 Promise 将被解析为包含加密结果的 <ArrayBuffer>。

【Using the method and parameters specified by algorithm and the keying material provided by key, subtle.encrypt() attempts to encipher data. If successful, the returned promise is resolved with an <ArrayBuffer> containing the encrypted result.】

目前支持的算法包括：

【The algorithms currently supported include:】

'RSA-OAEP'
'AES-CTR'
'AES-CBC'
'AES-GCM'
