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. |

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.
public:
virtual bool TrySignHash(ReadOnlySpan<System::Byte> hash, Span<System::Byte> destination, [Runtime::InteropServices::Out] int % bytesWritten);
public virtual bool TrySignHash (ReadOnlySpan<byte> hash, Span<byte> destination, out int bytesWritten);
abstract member TrySignHash : ReadOnlySpan<byte> * Span<byte> * int -> bool
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.
- bytesWritten
- Int32
When this method returns, the total number of bytes written into destination
. This parameter is treated as uninitialized.
Returns
false
if destination
is not long enough to receive the signature.

public:
bool TrySignHash(ReadOnlySpan<System::Byte> hash, Span<System::Byte> destination, System::Security::Cryptography::DSASignatureFormat signatureFormat, [Runtime::InteropServices::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.
- 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
signatureFormat
is not a known format.
An error occurred in the signing operation.
