What s the recommende way to get

What's the recommende way to get sha256 of a string nowdays? I'm trying

"use node";

import crypto from "crypto";

export function sha256(input: string): string {
  const hash = crypto.createHash("sha256").update(input).digest("hex");
  return hash;
}

"use node";

import crypto from "crypto";

export function sha256(input: string): string {
  const hash = crypto.createHash("sha256").update(input).digest("hex");
  return hash;
}

but I cannot make the this work for some reason...

Error

⠙ Preparing Convex functions...
✘ [ERROR] Could not resolve "crypto"

    convex/hash.ts:4:19:
      4 │ import crypto from "crypto";
        ╵                    ~~~~~~~~

Even after

npm i crypto

npm i crypto

ok I think solved this with adding this

  "browser": {
    "crypto": false
  }

  "browser": {
    "crypto": false
  }

to package.json

if you want to use browser crypto, which should work in queries/mutations/httpActions as well as node actions, you can do this

async function sha256(str: string) {
  const buffer = new TextEncoder().encode(str);
  const hash = await crypto.subtle.digest("SHA-256", buffer);
  // convert to hex
  return Array.from(new Uint8Array(hash)).map((b) => b.toString(16).padStart(2, "0")).join("");
}

async function sha256(str: string) {
  const buffer = new TextEncoder().encode(str);
  const hash = await crypto.subtle.digest("SHA-256", buffer);
  // convert to hex
  return Array.from(new Uint8Array(hash)).map((b) => b.toString(16).padStart(2, "0")).join("");
}

(without the "use node" or import crypto from "crypto")
