Symmetric algorithm using same key for encryption and decryption base class. 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....Emulates C#-style floating point comparison where two NaNs are considered...Emulates C#-style floating point comparison where two NaNs are considered...
