@joewalker Can you provide a reproduction with ssh2 module?

import crypto from "node:crypto";
import { Buffer } from "node:buffer";

var algorithm = "aes-256-ctr",
  password = "d6F3Efeq",
  key = Buffer.from("5ebe2294ecd0e0f08eab7690d2a6ee69", "hex"),
  iv = Buffer.from("26ae5cc854e36b6bdfca366848dea6bb", "hex");

function encrypt(text) {
  const cipher = crypto.createCipheriv("aes-128-cbc", key, iv);
  var crypted = cipher.update(text, "utf8", "hex");
  crypted += cipher.final("hex");
  return crypted;
}

function decrypt(text) {
  var decipher = crypto.createDecipheriv("aes-128-cbc", key, iv);
  var dec = decipher.update(text, "hex", "utf8");
  dec += decipher.final("utf8");
  return dec;
}

var hw = encrypt("hello world");
// outputs hello world
console.log(decrypt(hw));

Seems to work with deno 1.45.5+9a83efa. Please re-open if problem still exists.

@littledivy in your example you don't ever use the algorithm variable, and instead have hard coded the algorithm in createCipveriv to "aes-128-cbc",, so does this actually show anything?

If you update the code to use aes-256-ctr then deno v2 throws error: Uncaught (in promise) TypeError: Unknown cipher aes-256-ctr

function encrypt(text) {
  const cipher = crypto.createCipheriv(algorithm, key, iv);
  var crypted = cipher.update(text, "utf8", "hex");
  crypted += cipher.final("hex");
  return crypted;
}

function decrypt(text) {
  var decipher = crypto.createDecipheriv(algorithm, key, iv);
  var dec = decipher.update(text, "hex", "utf8");
  dec += decipher.final("utf8");
  return dec;
}

Oh nice catch!

• 1 for "aes-256-ctr" support please

Support for aes-256-ctr is definitely needed.

yikes is this still not supported.

same for aes-256-cbc

Ah well 3 days into deno land and I'm turning back, fun while it lasted

Node's docs for createCipheriv state:

The algorithm is dependent on OpenSSL, examples are 'aes192', etc. On recent OpenSSL releases, openssl list -cipher-algorithms will display the available cipher algorithms.

So maybe Deno implicitly supports "aes-256-ctr" and "aes-256-cbc" (etc.) as long as they are available with the local OpenSSL? That's just an optimistic guess. I don't even use Deno, I ended up here while researching something else 🙂
