## RSACryptoServiceProvider::SignData(const ByteArrayPtr\&, const SharedPtr\<Object\>\&) method


Computes the signature of specified input value.

```cpp
ByteArrayPtr System::Security::Cryptography::RSACryptoServiceProvider::SignData(const ByteArrayPtr &buffer, const SharedPtr<Object> &halg)
```


| Parameter | Type | Description |
| --- | --- | --- |
| buffer | const ByteArrayPtr\& | [Buffer](../../../system/buffer/) to read input data from. |
| halg | const SharedPtr\<Object\>\& | Hash algorithm to use. |

### ReturnValue

[RSA](../../rsa/) signature for specified data.
