Aes 256 o 128
La encripción de DES de las aplicaciones del Estándar de triple cifrado de datos (3DES) tres veces pero ahora es un algoritmo de la herencia. AES-128 has the lowest level of data security compared to AES 192 and AES 256, but AES 128 has the fastest data encryption and description process compared to AES 192 and AES 256 [10]. 11/02/2017 What is AES 256 bit-encryption?

The only supported ciphers are AES-128-CBC and AES-256-CBC with the correct key lengths. This is because you haven't created the APP_KEY in the .env file.

AES was designed to be efficient in both hardware and software, and supports a block length of 128 bits and key lengths of 128, 192, and 256 bits. From a paper via Schneier on Security's Another AES Attack (emphasis mine): In the case of AES-128, there is no known attack which is faster than the 2 128 complexity of exhaustive search. However, AES-192 and AES-256 were recently shown to be breakable by attacks which require 2176 and 2119 time, respectively. So for AES-128 the attack time becomes reduced to 2^64 (not very secure), while AES-256 becomes reduced to 2^128 which is still considered very secure. A Caveat. It is important to remember that 256-bit keys derived from passwords actually can have less than 256-bits of entropy. If the owner of the key generated it from a weak password an A key is just a number, and AES can work with keys of three different sizes, 128 bits, 192 bits, and 256 bits.

By contrast, Rijndael per se is specified with block and key sizes that may be any multiple of 32 bits, with a minimum of 128 and a maximum of 256 bits. AES operates on a 4 × 4 column-major order array of bytes, termed the state. El Advanced Encryption Standard, abreviado AES, se usa con el fin de cifrar datos y de protegerlos contra cualquier acceso ilícito. El método criptográfico emplea para este objetivo una clave de longitud variada y se denomina según la longitud de clave usada AES-128, AES-192 o AES-256. Esta clave puede ser de 128, 192 o 256 bits de tamaño. AES-256 – la versión clave de 256 bits de AES – es el estándar de cifrado utilizado por Le VPN. Es la forma más avanzada del cifrado y consiste en 14 rondas de sustitución, transposición y mezcla para un nivel de seguridad excepcionalmente alto.
Advanced Encryption Standard - Wikipedia, la enciclopedia libre
Intel Advanced Encryption Standard (AES) New Instructions Set. Round Keys AES-128, AES192, and AES-256 algorithms expand the cipher key to 10, 12, and 14 round keys, respectively. The length of each round key is 128 bits. I read recently that Fedora only offers AES 128 LUKS encryption. This just isn't secure enough for me. I want 256 or stronger for my Though here: How secure is Ubuntu's default full-disk encryption? it says that LUKS uses 256 - bit, or is this for Ubuntu only.

Let’s wrap this up… 256-bit encryption is fairly standard in 2019, but every mention of 256-bit AES stands for Advanced Encryption Standard.
