sign - crypto - Node

function sign

Usage in Deno

import { sign } from "node:crypto";



sign(algorithm: string
 | null
 | undefined,
data: ArrayBufferView,
key: KeyLike
 | SignKeyObjectInput
 | SignPrivateKeyInput
 | SignJsonWebKeyInput,
): Buffer

Calculates and returns the signature for data using the given private key and algorithm. If algorithm is null or undefined, then the algorithm is dependent upon the key type (especially Ed25519 and Ed448).

If key is not a KeyObject, this function behaves as if key had been passed to createPrivateKey. If it is an object, the following additional properties can be passed:

If the callback function is provided this function uses libuv's threadpool.

Parameters



algorithm: string
 | null
 | undefined



data: ArrayBufferView



key: KeyLike
 | SignKeyObjectInput
 | SignPrivateKeyInput
 | SignJsonWebKeyInput

Return Type

Buffer
