System::Security::Cryptography::RijndaelManaged Class Reference

Managed Rijndael algorithm. Only supports ECB and CFB modes with None padding and CBC mode with None and Zeros paddings. Objects of this class should only be allocated using System::MakeObject() function. Never create instance of this type on stack or using operator new, as it will result in runtime errors and/or assertion faults. Always wrap this class into System::SmartPtr pointer and use this pointer to pass it to functions as argument. More...
