I have this snippet from an old project, looks very similar to yours but uses a different package for sha1. Might be the solution, or not, idk
```ts
import sha1 from "js-sha1";
import crypto from "crypto";
import { BigInteger } from "jsbn";
export function createVerifier(username: string, password: string, salt: Buffer = null): Buffer {
// https://gist.github.com/Treeston/db44f23...cb8d66781e
const N = new BigInteger("894B645E89E1535BBDAD5B8B290650530801B18EBFBF5E8FAB3C82872A3E9BB7", 16);
const g = new BigInteger("7", 16);
salt = salt || generateSalt();
// Calculate first hash
const h1: Buffer = Buffer.from(sha1.arrayBuffer(`${username}:${password}`.toUpperCase()));
// Calculate second hash
const h2: Buffer = Buffer.from(sha1.arrayBuffer(Buffer.concat([salt, h1]))).reverse();
// Convert to integer
const h2bigint = new BigInteger(h2.toString("hex"), 16);
// g^h2 mod N
const verifierBigint = g.modPow(h2bigint, N);
// Convert back to a buffer
let verifier = Buffer.from(verifierBigint.toByteArray()).reverse();
// Pad to 32 bytes
verifier = verifier.slice(0, 32);
if (verifier.length != 32) {
verifier = Buffer.concat([verifier], 32);
}
return verifier;
};
export function generateSalt(): Buffer {
return crypto.randomBytes(32);
}
```

Precisely I was using yours before, but I switched to typescript so I tried to make an equivalent, precisely I located that sha1.ArrayBuffer is missing somewhere in relation to Javascript. Only the sha1 package does not offer this to tell the truth... I don't know how to do it
