Not implemented: crypto.Hmac error with Jsonwebtoken

[penberg]

Describe the bug

I am trying to use jsonwebtoken with Deno's compatibility mode, but I am seeing the following error:

Uncaught Error: Not implemented: crypto.Hmac

Steps to Reproduce

With the following webtoken.mjs file:

import jwt from 'jsonwebtoken'

const token = jwt.sign({ foo: 'bar' }, 'shhhhh');
console.log(token);

deno run (in compat mode) fails as follows:

% deno run --unstable --allow-env --allow-read --compat webtoken.mjs
error: Uncaught Error: Not implemented: crypto.Hmac
  throw new Error(message);
        ^

Expected behavior

% node webtoken.mjs

Environment

• OS: MacOS 12.4
• deno version: 1.24.3
• std version: 0.152.0

I'm taking a stab at this one!

Looks like there's some more unimplemented bits. As pointed out by @ricardodalarme, Octokit seems to use jsonwebtoken with RS256 algorith, which hits a different unimplemented path in crypto:

% cat webtoken.mjs
import jwt from 'jsonwebtoken'

const token = jwt.sign({ foo: 'bar' }, 'shhhhh', { algorithm: 'RS256' });

console.log(token);
% deno run --unstable --allow-env --allow-read --compat webtoken.mjs
error: Uncaught Error: Not implemented: crypto.Sign
  throw new Error(message);

@penberg alright! I'll take a look at it too, the HMAC implementation is kinda done, but there are still some tests missing and the type checking is not right too. I guess that I can take a look this Sunday

[ricardodalarme]

hey, @luk3skyw4lker any progress on that?

[luk3skyw4lker]

@ricardodalarme yep! I have made some progress on the PR, the tests are the only thing missing, I'll do them probably this weekend

[ricardodalarme]

okkk, thank you so much @luk3skyw4lker

This is the code:

I ran this same code in nodejs and it's worked well.
More info:

deno 1.26.1 (release, x86_64-unknown-linux-gnu)
v8 10.7.193.3
typescript 4.8.3

I know that googleapis is an npm packages and that is intended for nodejs but i wanted to try it with deno.
Is there any solution any solution for this or do I have to go back to nodejs? xd

googleapis seems to depend on gRPC, which is not yet supported in Deno, although it seems that it is being worked on denoland/deno#3326 (comment).

For the REST APIs, you may want to try the browser version: https://github.com/google/google-api-javascript-client

[josephrocca]

Maybe worth mentioning: This is also blocking npm AWS SDK usage. I wonder if there's any way to polyfill this with something like npm:node-forge in the meantime?

[iuioiua]

I'll give this a crack.

[elekram]

I'm getting error: Uncaught Error: Not implemented: crypto.Sign when trying to use Google APIs with NPM Specifiers. Is there a suggested work around for this in the meantime or should I trundle back to Node?

[cody880910]

All aliyun npm prompts: Not implemented: crypto.Hmac, is there a solution?

[WilsonNet]

I'll give this a crack.

thanks, it will help me a lot

For people stumbling here and using esm.sh to get JSON Web Token into deno; I had to force esm to use [email protected] via import jwt from "https://esm.sh/[email protected]?deno-std=0.166.0”;, else it defaults to 0.165.0

@gabobaxx @elekram Any solution found to solve this issue when trying to use with the googleapis?

[Ciscodefran]

No solutions yet?

[iuioiua]

The Standard Library no longer contains the implementation for the Node compatibility layer. If you're still having issues, please see the repo for the Deno CLI.

[elekram]

Not sure if this is of any help to anyone but I wrote a module that gets Google auth tokens and now I just use Google's REST apis/endpoints directly rather than using and relying on the googleapis package. Use it everyday for work.

[iuioiua]

To clarify, @Ciscodefran, if you still have issues, please open an issue in the Deno CLI repo.

[Ciscodefran]

Thank you so much @elekram . you are a legend :)
