Definition

Overloads

TrySignHash(ReadOnlySpan<Byte>, Span<Byte>, DSASignatureFormat, Int32)

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

TrySignHash(ReadOnlySpan<Byte>, Span<Byte>, Int32)

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.

TrySignHash(ReadOnlySpan<Byte>, Span<Byte>, DSASignatureFormat, Int32)

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

public:
 bool TrySignHash(ReadOnlySpan<System::Byte> hash, Span<System::Byte> destination, System::Security::Cryptography::DSASignatureFormat signatureFormat, [Runtime::InteropServices::Out] int % bytesWritten);
public bool TrySignHash (ReadOnlySpan<byte> hash, Span<byte> destination, System.Security.Cryptography.DSASignatureFormat signatureFormat, out int bytesWritten);
member this.TrySignHash : ReadOnlySpan<byte> * Span<byte> * System.Security.Cryptography.DSASignatureFormat * int -> bool
Public Function TrySignHash (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

Boolean

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

Exceptions

signatureFormat is not a known format.

An error occurred in the signing operation.

override this.TrySignHash : ReadOnlySpan<byte> * Span<byte> * int -> bool
Public Overridable Function TrySignHash (hash As ReadOnlySpan(Of Byte), destination As Span(Of Byte), ByRef bytesWritten As Integer) As Boolean

Parameters

hash
ReadOnlySpan<Byte>

The hash value of the data that is being signed.

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.
