Source:

HMACSHA256.cs

Attempts to compute the HMAC of data using the SHA256 algorithm.

public:
 static bool TryHashData(ReadOnlySpan<System::Byte> key, ReadOnlySpan<System::Byte> source, Span<System::Byte> destination, [Runtime::InteropServices::Out] int % bytesWritten);

public static bool TryHashData (ReadOnlySpan<byte> key, ReadOnlySpan<byte> source, Span<byte> destination, out int bytesWritten);

static member TryHashData : ReadOnlySpan<byte> * ReadOnlySpan<byte> * Span<byte> * int -> bool

Public Shared Function TryHashData (key As ReadOnlySpan(Of Byte), source As ReadOnlySpan(Of Byte), destination As Span(Of Byte), ByRef bytesWritten As Integer) As Boolean

Parameters

key

ReadOnlySpan<Byte>

The HMAC key.

source

ReadOnlySpan<Byte>

The data to HMAC.

destination

Span<Byte>

The buffer to receive the HMAC value.

bytesWritten

Int32

When this method returns, the total number of bytes written into destination.

Returns

Boolean

false if destination is too small to hold the calculated hash, true otherwise.
