Usage of weak hashing library (MD5)

Overview

• Rule ID: javascript_lang_weak_hash_md5

• Applicable Languages: Javascript

• Weakness ID: CWE-328

Description

Using a weak hashing library such as MD5 heightens the risk of data breaches. MD5 is susceptible to collision attacks, where different inputs generate the same output, compromising data integrity and security.

Remediation Guidelines

• Avoid using MD5 for hashing or security purposes, as it is no longer deemed secure for cryptographic applications.

• Choose more robust hashing algorithms, such as SHA-256, for improved security.

  const crypto = require("crypto");
  
  const key = "secret key";
  const hash = crypto.createHmac("sha256", key).update(user.password).digest('hex');
