Usage of weak encryption algorithm (RSA)

Description

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

Remediations

According to OWASP, 1024-bit RSA (Rivest-Shamir-Adleman) is considered a weak encryption algorithm and therefore shouldn't be used.

❌ Avoid libraries and algorithms with known weaknesses:

OpenSSL::PKey::RSA.new 1024

✅ Instead, we recommend using bcrypt:

BCrypt::Password.create('iLOVEdogs123')
