Usage of weak hashing library on a password (Argon2)

• Rule ID: javascript_lang_weak_password_hash_argon2
• Languages: javascript
• Source: weak_password_hash_argon2.yml

Description

Choosing a weak hashing algorithm for passwords compromises security. Argon2 has three variants: Argon2i, Argon2d, and Argon2id. Argon2id is the strongest and most recommended for password hashing because of its balanced resistance against both side-channel and GPU attack vectors.

Remediations

• Do not override the Argon2 type when implementing the Argon2 hashing library. Using Argon2id ensures the highest level of security for password storage.

    const argon2 = require("argon2");
    const hash = await argon2.hash(req.params.password, { type: argon2.argon2i }) // unsafe

• Do rely on the default Argon2 type - Argon2id as it is the most secure.

    const argon2 = require("argon2");
    const hash = await argon2.hash(req.params.password);
