## RSACryptoServiceProvider::SignHash(ByteArrayPtr, HashAlgorithmName, SharedPtr\<RSASignaturePadding\>) method


Computes the signature for the specified hash value.

```cpp
ByteArrayPtr System::Security::Cryptography::RSACryptoServiceProvider::SignHash(ByteArrayPtr hash, HashAlgorithmName hash_algorithm, SharedPtr<RSASignaturePadding> padding) override
```


| Parameter | Type | Description |
| --- | --- | --- |
| hash | ByteArrayPtr | Hash value. |
| hash_algorithm | HashAlgorithmName | Hash algorithm. |
| padding | SharedPtr\<RSASignaturePadding\> | Padding mode. return [RSA](../../rsa/) signature for the specified hash. |

```


| Parameter | Type | Description |
| --- | --- | --- |
| rgb_hash | const ByteArrayPtr\& | Hash value of data to be signed. |
| str | const String\& | Hash algorithm identifier used to create the hash. |

### ReturnValue
