RSAOpenSsl.SignHash(Byte[], HashAlgorithmName, RSASignaturePadding) Method

Definition

Namespace:

System.Security.Cryptography

Assembly:

System.Security.Cryptography.OpenSsl.dll

Computes the signature for the specified hash value using the specified padding.

public:
 override cli::array <System::Byte> ^ SignHash(cli::array <System::Byte> ^ hash, System::Security::Cryptography::HashAlgorithmName hashAlgorithm, System::Security::Cryptography::RSASignaturePadding ^ padding);

public override byte[] SignHash (byte[] hash, System.Security.Cryptography.HashAlgorithmName hashAlgorithm, System.Security.Cryptography.RSASignaturePadding padding);

override this.SignHash : byte[] * System.Security.Cryptography.HashAlgorithmName * System.Security.Cryptography.RSASignaturePadding -> byte[]

Public Overrides Function SignHash (hash As Byte(), hashAlgorithm As HashAlgorithmName, padding As RSASignaturePadding) As Byte()

Parameters

hash

Byte[]

The hash value of the data to be signed.

hashAlgorithm

HashAlgorithmName

The hash algorithm used to create the hash value of the data.

padding

RSASignaturePadding

The padding.

Returns

Byte[]

The RSA signature for the specified hash value.

Exceptions

ArgumentNullException

data or padding is null.

ArgumentException

hashAlgorithm.Name is null or Empty.

CryptographicException

padding is unknown, or not supported by this implementation.

-or-

This instance represents only a public key.

-or-

An error occurred creating the signature.
