Descriptions
The openssl gem for Ruby uses the same initialization vector (IV) in GCM Mode (aes-*-gcm) when the IV is set before the key, which makes it easier for context-dependent attackers to bypass the encryption protection mechanism.
La openssl gem para Ruby utiliza el mismo vector de inicialización (IV) en el modo GCM (aes - * - gcm) cuando el IV se establece en versiones anteriores a la clave, lo que facilita que los atacantes dependiendo del contexto eludan el mecanismo de protección del cifrado.
