RSACng::VerifyHash Method (array<Byte>^, array<Byte>^, HashAlgorithmName, RSASignaturePadding^)
Verifies data that was signed and already hashed with the specified algorithm and padding mode.
Assembly: System.Core (in System.Core.dll)
public: virtual bool VerifyHash( array<unsigned char>^ hash, array<unsigned char>^ signature, HashAlgorithmName hashAlgorithm, RSASignaturePadding^ padding ) override
Parameters
- hash
-
Type:
array<System::Byte>^
The hash to verify.
- signature
-
Type:
array<System::Byte>^
The signature of the data.
- hashAlgorithm
-
Type:
System.Security.Cryptography::HashAlgorithmName
The hash algorithm name.
- padding
-
Type:
System.Security.Cryptography::RSASignaturePadding^
The padding mode.
| Exception | Condition |
|---|---|
| ArgumentNullException | hash is null. -or- signature is null. -or- padding is null. |
| ArgumentException | The value of the HashAlgorithmName::Name property of hashAlgorithm is null or String::Empty. |
| CryptographicException | padding does not equal RSASignaturePadding::Pkcs1 or RSASignaturePadding::Pss. -or- The signature is badly formatted. (In the .NET Framework 4.6 and 4.6.1 only; starting with the .NET Framework 4.6.2, the method returns false if a signature is badly formatted. |
