verify - crypto - Node

function verify

Usage in Deno

import { verify } from "node:crypto";



verify(algorithm: string
 | null
 | undefined,
data: ArrayBufferView,
key: KeyLike
 | VerifyKeyObjectInput
 | VerifyPublicKeyInput
 | VerifyJsonWebKeyInput,
signature: ArrayBufferView,
): boolean

Verifies the given signature for data using the given 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 createPublicKey. If it is an object, the following additional properties can be passed:

The signature argument is the previously calculated signature for the data.

Because public keys can be derived from private keys, a private key or a public key may be passed for key.

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