ECDsa.TrySignHashCore Method

Definition

Attempts to create the ECDSA signature for the specified hash value in the indicated format into the provided buffer.

protected:
 virtual bool TrySignHashCore(ReadOnlySpan<System::Byte> hash, Span<System::Byte> destination, System::Security::Cryptography::DSASignatureFormat signatureFormat, [Runtime::InteropServices::Out] int % bytesWritten);
protected virtual bool TrySignHashCore (ReadOnlySpan<byte> hash, Span<byte> destination, System.Security.Cryptography.DSASignatureFormat signatureFormat, out int bytesWritten);
abstract member TrySignHashCore : ReadOnlySpan<byte> * Span<byte> * System.Security.Cryptography.DSASignatureFormat * int -> bool
override this.TrySignHashCore : ReadOnlySpan<byte> * Span<byte> * System.Security.Cryptography.DSASignatureFormat * int -> bool
Protected Overridable Function TrySignHashCore (hash As ReadOnlySpan(Of Byte), destination As Span(Of Byte), signatureFormat As DSASignatureFormat, ByRef bytesWritten As Integer) As Boolean

Parameters

hash
ReadOnlySpan<Byte>

The hash value to sign.

destination
Span<Byte>

The buffer to receive the signature.

signatureFormat
DSASignatureFormat

The encoding format to use for the signature.

bytesWritten
Int32

When this method returns, contains a value that indicates the number of bytes written to destination. This parameter is treated as uninitialized.

Returns

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

Exceptions

An error occurred in the signing operation.
