sign - node__crypto.d.ts - Node

function sign

Usage in Deno

```typescript import { sign } from "node:node__crypto.d.ts"; ```



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](../.././node__crypto.d.ts/~/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
