Usage of weak hashing library (DSS)

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

Description

Using a weak hashing library like DSS increases the risk of data breaches. DSS has known security flaws and vulnerabilities, and its use is no longer recommended.

Remediations

• Do not use DSS for hashing as it is considered a weak algorithm. This can compromise data security.

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

• Do opt for stronger hashing algorithms like bcrypt to enhance security.

  BCrypt::Password.create('iLOVEdogs123')
