Rendimiento aes 256 vs 128

What Is AES 256-Bit Encryption? AES was developed in response to the needs of the U.S. government. In 1977, federal agencies relied on the Data Encryption Standard (DES) as their encryption algorithm.

It has a fixed data block size of 16 bytes. Its keys can be 128, 192, or 256 bits long.

AES 256 - Traducci贸n al espa帽ol - ejemplos ingl茅s Reverso .

A 256-bit encryption key means there鈥檚 2256 possible combinations compared to 128-bit key which has 2128 possible combination a hacker would have try to break the encryption. In simple terms, 256-bit key takes 14 rounds of AES compare to 10 AES rounds of 128-bit key for each data block. Assuming you're talking about AES 128 versus AES 256, there is a known weakness in the key expansion function that affects AES256. Fundamentally, the weakness reduces the complexity of AES256 to that lower than AES128. There's a similar attack for AES192 as well, though in this case, the complexity of AES192 remains greater than AES128. AES-128 provides more than enough security margin for the foreseeable future. But if you're already using AES-256, there's no reason to change.鈥 A larger key size provides a higher safety margin against being cracked.
