## ECDsaBotan::HashData(ByteArrayPtr, int32_t, int32_t, HashAlgorithmName) method


Computes the hash value of the specified data array using the specified hash algorithm.

```cpp
ByteArrayPtr System::Security::Cryptography::ECDsaBotan::HashData(ByteArrayPtr data, int32_t offset, int32_t count, HashAlgorithmName hash_algorithm) override
```


| Parameter | Type | Description |
| --- | --- | --- |
| data | ByteArrayPtr | [Data](../../../system.data/) to hash. |
| offset | int32_t | Offset in **data**. |
| count | int32_t | Number of bytes to hash. |
| hash_algorithm | HashAlgorithmName | Hash algorithm. |

### ReturnValue

Hashed data.
