Usage of weak hashing library (SHA)

• Rule ID: ruby_lang_weak_hash_sha
• Languages: ruby
• Source: weak_hash_sha.yml

Description

Using a weak hashing library, such as SHA or SHA-1, compromises data security. These algorithms are no longer considered secure due to vulnerabilities that can lead to data breaches.

Remediations

• Do not use SHA or SHA-1 for hashing. These algorithms are outdated and vulnerable to attacks.

  Digest::SHA.hexdigest('weak hash')
  Digest::SHA1.hexdigest('weak hash')

• Do use stronger hashing algorithms like bcrypt for enhanced security.

  BCrypt::Password.create('iLOVEdogs123')
