HashData(ReadOnlySpan<Byte>)

Source:
SHA256.cs
Source:
SHA256.cs
Source:
SHA256.cs
Source:
SHA256.cs
Source:
SHA256.cs

Computes the hash of data using the SHA-256 algorithm.

public:
 static cli::array <System::Byte> ^ HashData(ReadOnlySpan<System::Byte> source);
public static byte[] HashData(ReadOnlySpan<byte> source);
static member HashData : ReadOnlySpan<byte> -> byte[]
Public Shared Function HashData (source As ReadOnlySpan(Of Byte)) As Byte()

Parameters

source
ReadOnlySpan<Byte>

The data to hash.

Returns

Byte[]

The hash of the data.

Applies to

HashData(Stream, Span<Byte>)

Source:
SHA256.cs
Source:
SHA256.cs
Source:
SHA256.cs
Source:
SHA256.cs
Source:
SHA256.cs

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

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

Parameters

source
Stream

The stream to hash.

destination
Span<Byte>

The buffer to receive the hash value.

Returns

The total number of bytes written to destination.

Exceptions

source is null.

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