Cifrado aes 128 vs 256
same key is used to encrypt and decrypt data. In AES, message is divided into block-size of 128 bits(16 bytes) to perform encryption or decryption operation.

(Nr). AES-128. 4.

Surprisingly it's not true for AES. AES-128 is (at the time I write this) more secore than AES-256. Regarding the performance overhead, using AES-256 will place an upper limit on your bandwith 10-15% lower than that for AES-128. I have not yet found any information about the latency, but expect AES-128 to outperform AES-256 significantly there. (AES-128 requiere el mismo vector de inicialización para cifrado y descifrado).
aes encryption and decryption algorithms - Traducción al .
AES encrypts and decrypts data in 128-bit blocks, using 128-, 192- or 256-bit keys. AES nomenclature for the different key sizes is AES-x, where x is the key size.) The biggest strength of AES lies in the various key lengths it provides, which enables you to choose between 128-, 192-, and 256-bit keys. The use of AES 256-bit encryption is fairly standard nowadays, and generally speaking in encryption, the longer the key is, the harder it is to crack (and the more secure it is). This is where the Advanced Encryption Standard (AES) comes in.

Partiendo de una clave inicial de 16 bytes (128 bits), que también se la puede ver como un 04/05/2019 12/10/2013 Un equipo de investigadores ha encontrado la primera vulnerabilidad en el estándar de cifrado AES reduciendo la longitud efectiva de la clave en 2 bits. Esto implica que las longitudes habituales de 128, 192 y 256 bits se han visto reducidas a 126, 190 y 254 bits. ¿Significa que está roto? AES (Advanced Encryption Standard) […] In normal use, AES keys are generated by a "truly" random source and never by a simple pseudorandom generator (like C++ rand()); AES256 is "more secure" than AES128 because it has 256-bit key - that means 2^256 possible keys to bruteforce, as opposed to 2^128 (AES128).

La configuración también incluye el protocolo de entrega (por ejemplo, MPEG-DASH, HSL, Smooth Streaming o todos) y el tipo de cifrado dinámico (por ejemplo, cifrado Envelope o cifrado no dinámico). (AES-128 requires the same IV for encryption and decryption.) Aquà aes-128-cbc y aes-128. aes significa servicio de cifrado avanzado, 128 es la velocidad de bits, y CBC es el modo de encriptación. Sin embargo, esto solo se enumera y se utiliza en los formatos OPEN SSL.Antes de Open SSL, PHP usaba mcrypt_encrypt que no estaba diseñado correctamente (versiones anteriores de PHP). When looking to access a system, hackers will always go for the weakest point, which isn’t going to be the encryption whether it’s a 128 bit key or a 256 bit key.
