For Rijndael, the block length and the key length can be independently specified to any multiple of 32 bits, with a minimum of 128 bits, and a maximum of 256 bits. But AES is the official standard and this standard only called for one block size 128 and those three keysizes.

Mathematical Preliminaries 3 2.1 The field GF(28) 3 AES is a subset of Rijndael ( FIPS-197 ). It's still being considered secure, if you continue reading to the bottom of the article: Even if the largest botnet ever discovered – the 30-million-computer-strong BredoLab botnet – was given the task of attacking an AES-256 implementation, the sheer number of possible combinations would make the task The S-box maps an 8-bit input, c, to an 8-bit output, s = S(c). Both the input and output are interpreted as polynomials over GF(2). First, the input is mapped to its multiplicative inverse in GF(2 8) = GF(2)[x]/(x 8 + x 4 + x 3 + x + 1), Rijndael's finite field. Zero, as the identity, is mapped to itself. Rijndael is the only AES finalist that suppor ts other block l engths than 128 bits, namely 192 bits and 256 bits.

Introducción a la criptografía: historia y actualidad

The length of the data packet must be 128 bits, and the length of the key used should be 128, 192 or 256 bits. For three AES algorithms with different key lengths, they are called "AES-128", "AES-192", "AES-256". Rijndael (pronounced rain-dahl) is the block cipher algorithm that has been selected by the U.S. National Institute of Standards and Technology (NIST) as the candidate for the Advanced Encryption Standard (AES). – Jason Sep 2 '14 at 10:17 1 Maybe you are really not a starter in VB/C++, but you are requesting us to give you an example using MS CryptoAPI, for which you are adamant that it does not support AES-256 (only in the comments).
