RSA.VerifyHash Method

Definition

Overloads

VerifyHash(Byte[], Byte[], HashAlgorithmName, RSASignaturePadding)

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.

VerifyHash(ReadOnlySpan<Byte>, ReadOnlySpan<Byte>, HashAlgorithmName, RSASignaturePadding)

VerifyHash(Byte[], Byte[], HashAlgorithmName, RSASignaturePadding)

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

true if the signature is valid; otherwise, false.

Exceptions

A derived class must override this method.
