# Usage of weak hashing library on a password (SHA-1)

## Overview

* **Rule ID**: `javascript_lang_weak_password_hash_sha1`
* **Applicable Languages**: Javascript
* **Weakness ID**: CWE-326

## Description

Using weak hashing algorithms like SHA-1 for password storage undermines security. These algorithms are prone to attacks, making it easier for attackers to crack passwords and access sensitive information.

## Remediation Guidelines

* **Avoid using SHA-1** for hashing passwords, as it is no longer deemed secure due to its susceptibility to various attacks.
* **Use a recommended hashing library like Argon2id** for hashing passwords. This method strengthens security by offering a more effective defense against brute-force attacks.

  ```javascript
  const argon2 = require("argon2");
  const hash = await argon2.hash(req.params.password, { type: argon2.argon2id })
  ```
