Usage of weak encryption algorithm (RSA)

• Rule ID: ruby_lang_weak_encryption_rsa
• Languages: ruby
• Source: weak_encryption_rsa.yml

Description

Using a weak encryption algorithm, specifically 1024-bit RSA, compromises data security. This vulnerability can lead to unauthorized access to sensitive information.

Remediations

• Do not use 1024-bit RSA for encryption. It is no longer considered secure.

  OpenSSL::PKey::RSA.new(1024) # unsafe

• Do use stronger encryption methods, such as bcrypt, to enhance security.

  BCrypt::Password.create('iLOVEdogs123')
