¿qué es el cifrado gcm aes de 256 bits_

XIP1113B from Xiphera is a balanced Intellectual Property (IP) core implementing the Advanced Encryption Standard (AES) • 128/256 bit AES-GCM (Galois/Counter Mode) – NIST Approved * • Line rate Encryption / Decryption for both 1/10/40/100GbE interface • Replay Protection of each and every frame. AES-GCN-256-bit Total MACSEC Ports Per System. Function Description. The Advanced Encryption Standard (AES) algorithm is a new NIST data encryption standard  The GCM3 implementation fully supports the AES algorithm for 128/192/256 bit keys in Galois Counter Mode (GCM) as required by the 802.1ae IEEE AES encryption on its own doesn’t provide any integrity of the data (unless using GCM mode to provide Authenticated Encryption with Associated Data – AEAD) so it is recommended to use something like HMAC-SHA-256. Direct encryption works with any of the six standard available content encryption algorithms (set by the "enc" JWE header parameter).

Por lo tanto, necesita aproximadamente (256/6) = 43 caracteres en la contraseña para contener unos 256 bits de aleatoriedad. Si la contraseña es memorable, necesita muchos más caracteres para alcanzar los 256 bits de aleatoriedad. La ejecución de texto en inglés tiene menos de 4 bits de aleatoriedad por byte. Puede que sea mejor tomar una larga frase de paso y generar un hash de 256 bits de eso (SHA-256, tal vez).
