method Verify.prototype.verify

Usage in Deno

import { Verify } from "node:crypto";



Verify.prototype.verify(object: KeyLike
 | VerifyKeyObjectInput
 | VerifyPublicKeyInput
 | VerifyJsonWebKeyInput,
signature: ArrayBufferView,
): boolean

Verifies the provided data using the given object and signature.

If object is not a KeyObject, this function behaves as if object 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, in the signatureEncoding. If a signatureEncoding is specified, the signature is expected to be a string; otherwise signature is expected to be a Buffer, TypedArray, or DataView.

The verify object can not be used again after verify.verify() has been called. Multiple calls to verify.verify() will result in an error being thrown.

Because public keys can be derived from private keys, a private key may be passed instead of a public key.
