## RSACryptoServiceProvider::VerifyHash(ByteArrayPtr, ByteArrayPtr, const HashAlgorithmName\&, SharedPtr\<RSASignaturePadding\>) method


Verifies that the signature of the specified hash is valid.

```cpp
bool System::Security::Cryptography::RSACryptoServiceProvider::VerifyHash(ByteArrayPtr hash, ByteArrayPtr signature, const HashAlgorithmName &hash_algorithm, SharedPtr<RSASignaturePadding> padding) override
```


| Parameter | Type | Description |
| --- | --- | --- |
| hash | ByteArrayPtr | Hash value of the signed data. |
| signature | ByteArrayPtr | Signature data. |
| hash_algorithm | const HashAlgorithmName\& | Hash algorithm. |
| padding | SharedPtr\<RSASignaturePadding\> | Padding mode. return true if signature is valid, otherwise - false. |

## RSACryptoServiceProvider::VerifyHash(const ByteArrayPtr\&, const String\&, const ByteArrayPtr\&) method


Checks data signature.

```cpp
bool System::Security::Cryptography::RSACryptoServiceProvider::VerifyHash(const ByteArrayPtr &rgb_hash, const String &str, const ByteArrayPtr &rgb_signature)
```


| Parameter | Type | Description |
| --- | --- | --- |
| rgb_hash | const ByteArrayPtr\& | Hash calculated for received data. |
| str | const String\& | Name of hash algorithm used. |
| rgb_signature | const ByteArrayPtr\& | Signature as received. |

### ReturnValue

True if signature is valid, false otherwise.
