## HashAlgorithm::ComputeHash(SharedPtr\<IO::Stream\> const\&) method


Reads stream until end and calculates hash for the data read.

```cpp
ArrayPtr<uint8_t> System::Security::Cryptography::HashAlgorithm::ComputeHash(SharedPtr<IO::Stream> const &inputStream)
```


| Parameter | Type | Description |
| --- | --- | --- |
| inputStream | SharedPtr\<IO::Stream\> const\& | Stream to read data from. |

### ReturnValue

Calculated hash value for the whole stream data.
