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

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

protected virtual bool TrySignDataCore(ReadOnlySpan<byte> data, Span<byte> destination, System.Security.Cryptography.HashAlgorithmName hashAlgorithm, System.Security.Cryptography.DSASignatureFormat signatureFormat, out int bytesWritten);

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

Protected Overridable Function TrySignDataCore (data As ReadOnlySpan(Of Byte), destination As Span(Of Byte), hashAlgorithm As HashAlgorithmName, signatureFormat As DSASignatureFormat, ByRef bytesWritten As Integer) As Boolean

Parameters

data: ReadOnlySpan<Byte>

The data to hash and sign.

destination: Span<Byte>

The buffer to receive the signature.

hashAlgorithm: HashAlgorithmName

The hash algorithm to use to create the hash value.

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

Boolean

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

Exceptions

CryptographicException

An error occurred in the signing operation.
