ECDsaCng.TrySignHash Method

Definition

Namespace:

System.Security.Cryptography

Assembly:

System.Security.Cryptography.dll

Attempts to compute the ECDSA digital signature for the specified read-only span of bytes representing a data hash into the provided destination by using the current key.

public:
 override bool TrySignHash(ReadOnlySpan<System::Byte> source, Span<System::Byte> destination, [Runtime::InteropServices::Out] int % bytesWritten);

public override bool TrySignHash (ReadOnlySpan<byte> source, Span<byte> destination, out int bytesWritten);

override this.TrySignHash : ReadOnlySpan<byte> * Span<byte> * int -> bool

Public Overrides Function TrySignHash (source As ReadOnlySpan(Of Byte), destination As Span(Of Byte), ByRef bytesWritten As Integer) As Boolean

Parameters

source

ReadOnlySpan<Byte>

destination

Span<Byte>

The buffer to receive the signature.

bytesWritten

Int32

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

Returns

Boolean

false if destination is not long enough to receive the signature.
