You linked to the RijndaelManaged class. The AesCryptoServiceProvider class (which uses the Rijndael algorithm for block encryption) uses the Windows' Cryptographic Service Provider API. This class is mostly just a .NET shell that passes the data onto one of various Windows DLLs written in C/C++ to do the actual encryption. // Create a new instance of the AesCryptoServiceProvider // class. This generates a new key and initialization // vector (IV). using (AesCryptoServiceProvider myAes = new AesCryptoServiceProvider()) { // Encrypt the string to an array of bytes. Examples. The following example demonstrates how to encrypt and decrypt sample data using the RijndaelManaged class..

For AES, NIST selected three members of the Rijndael family, each with a block size of 128 bits, but three different key lengths: 128, 192 and 256 bits. AES has been adopted by the U.S. government. It supersedes the Data Encryption Standard (DES), which was published in 1977. Advanced Encryption Standard (or for short AES, also known as Rijndael) is a powerful symmetric block cypher approved by NIST. It uses 128-bit blocks and keys at the size of 128, 192 and 256 bits. AES uses a transformation schema, where it first using a substitution table, then shifts data rows, then mixes columns to finally do a simple XOR It first creates round keys by expanding the original key using the Rijndael key scheduler algorithm. It then encrypts the block by substituting bytes using the Rijndael S-box, shifting bytes, diffusing bytes using a Galois field, and adding the round key.
