## RSA::VerifyData(const ByteArrayPtr\&, const ByteArrayPtr\&, const HashAlgorithmName\&, const SharedPtr\<RSASignaturePadding\>\&) method


Verifies that the signature of the specified data is valid.

```cpp
bool System::Security::Cryptography::RSA::VerifyData(const ByteArrayPtr &data, const ByteArrayPtr &signature, const HashAlgorithmName &hash_algorithm, const SharedPtr<RSASignaturePadding> &padding)
```


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