RSACryptoServiceProvider::VerifyHash Method (array<Byte>^, array<Byte>^, HashAlgorithmName, RSASignaturePadding^)

 

Verifies that a digital signature is valid by determining the hash value in the signature using the specified hashing algorithm and padding, and comparing it to the provided hash value.

Namespace:   System.Security.Cryptography
Assembly:  mscorlib (in mscorlib.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 value of the signed data.

signature
Type: array<System::Byte>^

The signature data to be verified.

hashAlgorithm
Type: System.Security.Cryptography::HashAlgorithmName

The hash algorithm name used to create the hash value.

padding
Type: System.Security.Cryptography::RSASignaturePadding^

The padding.

Return Value

Type: System::Boolean

true if the signature is valid; otherwise, false.

Exception Condition
ArgumentException

hashAlgorithm is null or String::Empty.

ArgumentNullException

hash is null.

-or-

padding is null.

CryptographicException

padding does not equal RSASignaturePadding::Pkcs1.
