Weak password hashing (SHA) detected.

• Rule ID: ruby_lang_weak_password_hash_sha
• Languages: ruby
• Source: weak_password_hash_sha.yml

Description

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

Remediations

According to OWASP, SHA and SHA1 are considered weak hash algorithms and therefore shouldn't be used.

✅ Use a recommended hashing library such as bcrypt or Argon2id for passwords

BCrypt::Password.create("password_123")

hasher = Argon2::Password.new()
hasher.create("password_123")
