Definition

Namespace:

System.Security.Cryptography

Assembly:

System.Security.Cryptography.dll

Overloads

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.

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

Source:

ECDsa.cs

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.

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.

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

Source:

ECDsa.cs

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

ArgumentOutOfRangeException

signatureFormat is not a known format.

CryptographicException

An error occurred in the signing operation.
