Remarks

The AES algorithm is essentially the Rijndael symmetric algorithm with a fixed block size and iteration count. This class functions the same way as the RijndaelManaged class but limits blocks to 128 bits and does not allow feedback modes.

Note

If the Windows security policy setting for Federal Information Processing Standards (FIPS)-compliant algorithms is enabled, using this algorithm throws a CryptographicException.

Note

Microsoft believes that it's no longer safe to decrypt data encrypted with the Cipher-Block-Chaining (CBC) mode of symmetric encryption (which is the default value of the Mode property) when verifiable padding has been applied without first ensuring the integrity of the ciphertext, except for very specific circumstances. For more information, see Timing vulnerabilities with CBC-mode symmetric decryption using padding.
