The Rijndael class is the predecessor of the Aes algorithm. You should use the Aes algorithm instead of Rijndael. For more information, see the entry The Differences Between Rijndael and AES in the .NET Security blog. Constructors

Rijndael、AES、AesManaged、AesCryptoServiceProvider類的對比 Rijndael是AES的早期版本,也就是在它被選為AES那個時候的版本。 AES 算法實質上是具有固定塊大小和迭代計數的 Rijndael 對稱算法。 Rijndael的BlockSize支持128, 160, 192, 224, 256bits。

22/2/2019 · This is a small and portable implementation of the AES ECB, CTR and CBC encryption algorithms written in C. You can override the default key-size of 128 bit with 192 or 256 bit by defining the symbols AES192 or AES256 in aes.h. You can choose to

9/10/2006 · After all, Rijndael was the winner of the NIST competition to select the algorithm that would become AES. However, there are some differences between Rijndael and the official FIPS-197 specification for AES. Namely, Rijndael allows for both key and block sizes

接下來我們來看範例 下段比較值得注意的是編碼的部份, 1.下段是用Encoding.UTF8.GetBytes(source)來取得原始資料的Byte,所以解密的時候也要用Encoding.UTF8 2.另外加密後的Byte Convert String是用Convert.ToBase64String所以解密的時候也要用相對應的方式
