Source:
HMACSHA256.cs
Source:
HMACSHA256.cs
Source:
HMACSHA256.cs
Source:
HMACSHA256.cs

Computes the HMAC of a stream using the SHA-256 algorithm.

public:
 static int HashData(ReadOnlySpan<System::Byte> key, System::IO::Stream ^ source, Span<System::Byte> destination);
public static int HashData(ReadOnlySpan<byte> key, System.IO.Stream source, Span<byte> destination);
static member HashData : ReadOnlySpan<byte> * System.IO.Stream * Span<byte> -> int
Public Shared Function HashData (key As ReadOnlySpan(Of Byte), source As Stream, destination As Span(Of Byte)) As Integer

Parameters

key
ReadOnlySpan<Byte>

The HMAC key.

source
Stream

The stream to HMAC.

destination
Span<Byte>

The buffer to receive the HMAC value.

Returns

Int32

The total number of bytes written to destination.

Exceptions

ArgumentNullException

source is null.

ArgumentException

The buffer in destination is too small to hold the calculated HMAC size. The SHA-256 algorithm always produces a 256-bit HMAC, or 32 bytes.

-or-

source does not support reading.
