Attempts to compute the ECDSA digital signature for the specified read-only span of bytes into the provided destination by using the specified hashing algorithm and the current key.

public:
 virtual bool TrySignData(ReadOnlySpan<System::Byte> data, Span<System::Byte> destination, System::Security::Cryptography::HashAlgorithmName hashAlgorithm, [Runtime::InteropServices::Out] int % bytesWritten);

public virtual bool TrySignData(ReadOnlySpan<byte> data, Span<byte> destination, System.Security.Cryptography.HashAlgorithmName hashAlgorithm, out int bytesWritten);

abstract member TrySignData : ReadOnlySpan<byte> * Span<byte> * System.Security.Cryptography.HashAlgorithmName * int -> bool
override this.TrySignData : ReadOnlySpan<byte> * Span<byte> * System.Security.Cryptography.HashAlgorithmName * int -> bool

Public Overridable Function TrySignData (data As ReadOnlySpan(Of Byte), destination As Span(Of Byte), hashAlgorithm As HashAlgorithmName, ByRef bytesWritten As Integer) As Boolean

Parameters

data: ReadOnlySpan<Byte>

The data to be signed.

destination: Span<Byte>

The buffer to receive the signature.

hashAlgorithm: HashAlgorithmName

The algorithm to use to hash the data for signing.

bytesWritten: Int32

When this method returns, contains 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.
