Weak encryption library usage detected.

• Rule ID: javascript_lang_weak_encryption
• Languages: javascript
• Source: weak_encryption.yml

Description

Sensitive data should be encrypted with strong encryption algorithms like aes-256-cbc

Remediations

According to OWASP: MD5, RC4, DES, Blowfish, SHA1. 1024-bit RSA or DSA, 160-bit ECDSA (elliptic curves), 80/112-bit 2TDEA (two key triple DES) are considered as weak hash/encryption algorithms and therefore shouldn't be used.

✅ Use stronger encryption algorithms when storing data.

const crypto = require("crypto");

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