RSAOpenSsl.VerifyHash Method

Definition

Namespace:

System.Security.Cryptography

Assembly:

System.Security.Cryptography.OpenSsl.dll

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

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 value of the signed data.

signature

Byte[]

The signature data to be verified.

hashAlgorithm

HashAlgorithmName

The hash algorithm used to create the hash value.

padding

RSASignaturePadding

The padding mode.

Returns

Boolean

true if the signature is valid; otherwise, false.

Exceptions

ArgumentNullException

hash or padding is null.

ArgumentException

hashAlgorithm.Name is null or Empty.

CryptographicException

padding is unknown, or not supported by this implementation.
