# Usage of weak encryption algorithm (DES)

## Overview

* **Rule ID**: `javascript_lang_weak_encryption_des`
* **Applicable Languages**: Javascript
* **Weakness ID**: CWE-327

## Description

Your code is vulnerable due to the use of DES (Data Encryption Standard), which is a weak encryption algorithm. This vulnerability can result in data breaches and undermine your security measures.

## Remediation Guidelines

* **Avoid using DES**, as it is outdated and susceptible to attacks. Its use can considerably compromise your application's security.
* **Choose stronger encryption algorithms**, like AES (Advanced Encryption Standard), to maintain the confidentiality and integrity of your data.

  ```javascript
  const crypto = require("crypto");

  const cipher = crypto.createCipheriv("aes-256-cbc", key, iv);
  const encrypted = cipher.update("my secret message", "utf8");
  ```
