subtle.sign(algorithm, key, data)


使用 algorithm 提供的方法和参数以及 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 将会被解决,并返回一个包含生成签名的 <ArrayBuffer>

【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.】

目前支持的算法包括:

【The algorithms currently supported include:】

  • 'RSASSA-PKCS1-v1_5'
  • 'RSA-PSS'
  • 'ECDSA'
  • 'Ed25519'
  • 'Ed448' 1
  • 'HMAC'
