RSACng.VerifyHash Method

Definition

Namespace:
System.Security.Cryptography
Assembly:
System.Core.dll

Verifies data that was signed and already hashed with the specified algorithm and padding mode.

public:
 override bool VerifyHash(cli::array <System::Byte> ^ hash, cli::array <System::Byte> ^ signature, System::Security::Cryptography::HashAlgorithmName hashAlgorithm, System::Security::Cryptography::RSASignaturePadding ^ padding);
public override bool VerifyHash(byte[] hash, byte[] signature, System.Security.Cryptography.HashAlgorithmName hashAlgorithm, System.Security.Cryptography.RSASignaturePadding padding);
override this.VerifyHash : byte[] * byte[] * System.Security.Cryptography.HashAlgorithmName * System.Security.Cryptography.RSASignaturePadding -> bool
Public Overrides Function VerifyHash (hash As Byte(), signature As Byte(), hashAlgorithm As HashAlgorithmName, padding As RSASignaturePadding) As Boolean

Parameters

hash
Byte[]

The hash to verify.

signature
Byte[]

The signature of the data.

hashAlgorithm
HashAlgorithmName

The hash algorithm name.

padding
RSASignaturePadding

The padding mode.

Returns

Boolean

true if the signature verifies for the hash; otherwise, false.

Exceptions

ArgumentNullException

hash is null.

-or-

signature is null.

-or-

padding is null.

ArgumentException

The value of the Name property of hashAlgorithm is null or Empty.

CryptographicException

padding does not equal Pkcs1 or 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.
