The SubtleCrypto.sign() method returns a Promise containing the signature corresponding to the text, algorithm and key given as parameters.
var signature = crypto.subtle.sign(algo, key, text2sign);
algo is a DOMString defining the signature function to use. Supported values are: HMAC, RSASSA-PKCS1-v1_5, and ECDSA.CryptoKey containing the private key to be used for signing.text2sign is a ArrayBuffer or an ArrayBufferView containing the data to be signed.signature is a Promise that returns the signature on success.The promise is rejected when the following exception is encountered:
InvalidAccessError when the signing key is not a key for the request signing algorithm or when trying to use an algorithm that is either unknown or isn't suitable for signing.| Specification | Status | Comment |
