## X509Certificate class


X.509 v.3 certificate. Encrypted certificates are not supported. Only [X509KeyStorageFlags::DefaultKeySet](../x509keystorageflags/) flag is supported. Objects of this class should only be allocated using [System::MakeObject()](../../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](../../system/smartptr/) pointer and use this pointer to pass it to functions as argument.

```cpp
class X509Certificate : public virtual System::Object,
                        public System::IDisposable
```
