Weak encryption algorithm (RC4) detected.

• Rule ID: javascript_lang_weak_encryption_rc4
• Languages: javascript
• Source: weak_encryption_rc4.yml

Description

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

Remediations

According to OWASP, RC4 (Rivest Cipher 4) is considered a weak encryption algorithm and therefore shouldn't be used.

✅ Use stronger encryption algorithms when storing data.

const crypto = require("crypto");

const cipher = crypto.createCipheriv("aes-256-cbc", key, iv);

const encrypted = cipher.update("my secret message", "utf8");
