Verifies that a digital signature is valid for the provided hash.

public:
 bool VerifyHash(cli::array <System::Byte> ^ hash, cli::array <System::Byte> ^ signature, System::Security::Cryptography::DSASignatureFormat signatureFormat);
public bool VerifyHash (byte[] hash, byte[] signature, System.Security.Cryptography.DSASignatureFormat signatureFormat);
member this.VerifyHash : byte[] * byte[] * System.Security.Cryptography.DSASignatureFormat -> bool
Public Function VerifyHash (hash As Byte(), signature As Byte(), signatureFormat As DSASignatureFormat) As Boolean

Parameters

hash
Byte[]

The signed hash.

signature
Byte[]

The signature to verify.

signatureFormat

The encoding format for signature.

Returns

true if the digital signature is valid for the provided data; otherwise, false.

Exceptions

hash or signature is null.

signatureFormat is not a known format.
