Deno panic on node:crypto createCipheriv with key provided as string

[jacobhaap]

Version: Deno 2.1.7

When using the createCipheriv function from node:crypto, deno panics when the key provided to the createCipheriv function with the aes-256-gcm algorithm is of type string (string provided for a key of type CipherKey, alias for BinaryLike/string).

This is reproducible in TypeScript via the following script:

import { randomBytes, createCipheriv } from "node:crypto";
import type { CipherGCMTypes, CipherKey, BinaryLike, CipherGCM } from "node:crypto";

const algorithm: CipherGCMTypes = "aes-256-gcm";
const key: CipherKey = randomBytes(32).toString('hex');
const iv: BinaryLike = randomBytes(16);

const text: string = "Greetings Fellow Humans";

const cypher: CipherGCM = createCipheriv(algorithm, key, iv);
let cyphertext: string = cypher.update(text, 'utf8', 'hex');
cyphertext += cypher.final('hex');

When the key is provided as Buffer (const key: CipherKey = randomBytes(32);), Deno does not panic and createCipheriv functions normally.

Deno panic:

Deno has panicked. This is a bug in Deno. Please report this

If you can reliably reproduce this panic, include the
reproduction steps and re-run with the RUST_BACKTRACE=1 env
var set and include the backtrace in your report.
