webcrypto.SubtleCrypto.sign - crypto - Node

method webcrypto.SubtleCrypto.sign

Usage in Deno

import { type webcrypto } from "node:crypto";



SubtleCrypto.sign(algorithm: AlgorithmIdentifier
 | RsaPssParams
 | EcdsaParams
 | Ed448Params,
key: CryptoKey,
data: BufferSource,
): Promise<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.

The algorithms currently supported include:

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

Parameters



algorithm: AlgorithmIdentifier
 | RsaPssParams
 | EcdsaParams
 | Ed448Params



key: CryptoKey



data: BufferSource

Return Type

Promise<ArrayBuffer>
