Source:

ECDsa.cs

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.
