Weak hashing library (SHA1) detected.

• Rule ID: javascript_lang_weak_hash_sha1
• Languages: javascript
• Source: weak_hash_sha1.yml

Description

A weak hashing library can lead to data breaches and greater security risk.

Remediations

According to OWASP, SHA1 is considered a weak hash algorithm and therefore shouldn't be used.

✅ Use stronger hashing algorithms when storing data.

const crypto = require("crypto");

const key = "secret key";
const hash = crypto.createHmac("es-256-cbc", key).update(user.password);
