Usage of weak encryption algorithm on a password (RC4)

Description

A weak encryption library can lead to data breaches and greater security risk. Moreover, since encryption is reversible, it is possible to retrieve the plaintext value. This makes encryption a bad choice for passwords. Instead, passwords should be hashed.

Remediations

❌ Do not use encryption for passwords, wherever possible.

✅ 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")
