Rijndael 128 frente a aes 256
The more rounds, the more complex the encryption, making AES 256 the most secure AES implementation. It should be noted that with a longer key and more rounds comes higher performance requirements. Estoy encriptando una comunicación entre usuarios y al desencriptar lo hace de manera parcial.

Each transformation is known as a round, and Rijndael uses a variable amount of them depending on the key or block sizes being employed.

¿Significa que está roto? AES (Advanced Encryption Standard) es en realidad el algoritmo Rijndael, que pasó a ser un estándar de cifrado aprobado por el gobierno de los Estados Unidos en 2003 para cifrar información clasificada. No existe soporte en ninguno de los proveedores de Sun JCE para nada más que Rijndael con el tamaño de bloques de 128 bits: este es el algoritmo AES. Para obtener rijndael con el tamaño de bloque de 256 bits, tendrá que ir a otro lugar. Sugiero la biblioteca de Bouncycastle java.

The following diagram provides a simplified overview of the AES process… Plain text. This is the sensitive data that you wish to encrypt O AES tem um tamanho de bloco fixo em 128 bits e uma chave com tamanho de 128, 192 ou 256 bits, enquanto o Rijndael pode ser especificado com chaves e tamanhos de bloco de qualquer múltiplo de 32 bits, com um mínimo de 128 bits e um máximo de 256 bits. A chave é expandida usando-se o escalonamento de chaves do Rijndael. AES is een subset van het Rijndael-algoritme waarbij de blokgrootte 128-bits is, en de sleutel 128, 192 of 256 bits.

q Based on a competition won by Rijmen q Rijndael allows many block sizes and key sizes. q AES restricts it to: Ø Block Size: 128 bits. Ø Key sizes: 128, 192, 256 (AES-128 AES is only the 128-bit block version of Rijndael (which can use 128-, 192-, and 256-bit keys). The following PHP class does encryption and decryption with AES-128 and uses HMAC-SHA256 for authentication. However, AES-192 and AES-256 were recently shown to be breakable by attacks which This seems to suggest AES128 is stronger than AES256.

AES-256 으로 암호화 하기위해 The Advanced Encryption Standard was originally known as Rijndael. The AES has three fixed 128-bit block ciphers with cryptographic key sizes of 128, 192 and 256 bits. Key size is unlimited, whereas the block size maximum is 256 bits.
