ECDsa.TryHashData Method

Definition

Namespace:

System.Security.Cryptography

Assembly:

System.Security.Cryptography.dll

Source:

ECDsa.cs

Attempts to compute the hash value of the specified read-only span of bytes into the provided destination by using the specified hashing algorithm.

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

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

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

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

Parameters

data

ReadOnlySpan<Byte>

The data to be hashed.

destination

Span<Byte>

The buffer to receive the hash value.

hashAlgorithm

HashAlgorithmName

The algorithm to use to hash the data.

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 hash value.

Remarks

The default implementation of this method is to call HashData(Byte[], Int32, Int32, HashAlgorithmName) and copy the result to destination. Derived types should override this method to avoid the intermediate array creation.
