Exceptions

ArgumentNullException

source is null.

ArgumentException

source does not support reading.

HashData(ReadOnlySpan<Byte>, ReadOnlySpan<Byte>)

Source:

HMACSHA512.cs

Computes the HMAC of data using the SHA512 algorithm.

public:
 static cli::array <System::Byte> ^ HashData(ReadOnlySpan<System::Byte> key, ReadOnlySpan<System::Byte> source);

public static byte[] HashData (ReadOnlySpan<byte> key, ReadOnlySpan<byte> source);

static member HashData : ReadOnlySpan<byte> * ReadOnlySpan<byte> -> byte[]

Public Shared Function HashData (key As ReadOnlySpan(Of Byte), source As ReadOnlySpan(Of Byte)) As Byte()

Parameters

key

ReadOnlySpan<Byte>

The HMAC key.

source

ReadOnlySpan<Byte>

The data to HMAC.

Returns

Byte[]

The HMAC of the data.

HashData(ReadOnlySpan<Byte>, Stream, Span<Byte>)

Source:

HMACSHA512.cs

Computes the HMAC of a stream using the SHA512 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 SHA512 algorithm always produces a 512-bit HMAC, or 64 bytes.

-or-

source does not support reading.
