RSACng.TrySignHash Method

Definition

Namespace:

System.Security.Cryptography

Assembly:

System.Security.Cryptography.dll

Attempts to sign the hash with the current key, writing the signature into a provided buffer.

public:
 override bool TrySignHash(ReadOnlySpan<System::Byte> hash, Span<System::Byte> destination, System::Security::Cryptography::HashAlgorithmName hashAlgorithm, System::Security::Cryptography::RSASignaturePadding ^ padding, [Runtime::InteropServices::Out] int % bytesWritten);

public override bool TrySignHash (ReadOnlySpan<byte> hash, Span<byte> destination, System.Security.Cryptography.HashAlgorithmName hashAlgorithm, System.Security.Cryptography.RSASignaturePadding padding, out int bytesWritten);

override this.TrySignHash : ReadOnlySpan<byte> * Span<byte> * System.Security.Cryptography.HashAlgorithmName * System.Security.Cryptography.RSASignaturePadding * int -> bool

Public Overrides Function TrySignHash (hash As ReadOnlySpan(Of Byte), destination As Span(Of Byte), hashAlgorithm As HashAlgorithmName, padding As RSASignaturePadding, ByRef bytesWritten As Integer) As Boolean

Parameters

hash

ReadOnlySpan<Byte>

The hash value of the data to be signed.

destination

Span<Byte>

The buffer to receive the RSA signature.

hashAlgorithm

HashAlgorithmName

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

padding

RSASignaturePadding

The padding.

bytesWritten

Int32

When this method returns, the total number of bytes written into destination. This parameter is treated as uninitialized.

Returns

Boolean

true if destination is long enough to receive the RSA signature; otherwise, false.
