Des vs aes 256
Through a firmware upgrade I now have the option of using AES-256 on my VPNs instead of 3DES with essentially the same throughput. Not sure weather to use AES-128/AES-256/3DES. As much ive read (links down under) that suggest AES encryption is slightly better (and of course it replaces 3DES due to NIST saying it is a bit deprecated). A comparison of two encryption standards, 3DES and AES is presented. It may seem that DES is insecure and no longer of any use, but that is not the case since the DES and 3DES algorithms are still beyond the capability of most attacks in the present day. DES vs AES-difference between DES and AES. Both are encryption or cryptography algorithms designed mainly to provide secure communication between two parties.
Understanding the SSH Encryption and Connection Process .
In cryptography, Triple DES (3DES or TDES), officially the Triple Data Encryption Algorithm (TDEA or Triple DEA), is a symmetric-key block cipher, which applies the DES cipher algorithm three times to each data block.

For XTS decryption, we see a 30% improvement for 256-bit XTS keys over 512-bit keys.

Esto se diseñó en base a la Ley de Moore , ya que las primeras pruebas demostraron que, en un tiempo relativamente corto, la potencia de los procesadores podría romper el cifrado más débil en periodos de tiempo cada vez menores. Estrictamente hablando, AES no es precisamente Rijndael (aunque en la práctica se los llama de manera indistinta) ya que Rijndael permite un mayor rango de tamaño de bloques y longitud de claves; AES tiene un tamaño de bloque fijo de 128 bits y tamaños de llave de 128, 192 o 256 bits, mientras que Rijndael puede ser especificado por una clave que sea múltiplo de 32 bits, con un mínimo de 128 bits y un máximo de 256 bits. The three AES varieties are also distinguished by the number of rounds of encryption. AES 128 uses 10 rounds, AES 192 uses 12 rounds, and AES 256 uses 14 rounds. The more rounds, the more complex the encryption, making AES 256 the most secure AES implementation. 2. AES256SHA256 uses AES in CBC mode for encryption.

On the Other hand, AES works with 128, 192, and 256 bits key. Furthermore, this algorithm makes use of a 128-bit block that is quite convenient for both the hardware and the software.

Through a firmware upgrade I now have the option of using AES-256 on my VPNs instead of 3DES with essentially the same throughput. To take advatage of this upgrade, I need to shuffle around a few firewalls.
