Weak hashing library (DSS) detected.

• Rule ID: ruby_lang_weak_hash_dss
• Languages: ruby
• Source: weak_hash_dss.yml

Description

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

Remediations

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

❌ Avoid libraries and algorithms with known weaknesses:

OpenSSL::Digest.new("dss").digest("weak")

✅ Instead, we recommend using bcrypt:

BCrypt::Password.create('iLOVEdogs123')
